supplies such as pacemakers, ventilators, CAT scans and even the hospitals themselves, or consumer goods like computers and televisions, or the phosphate fertilizers used to grow our food and feed the world’s population. Historically these minerals have been the backbone of our society’s daily needs and they will be the base of electric vehicles and renewable energy technologies going into the future. Here in Idaho we have one of the most diverse sets of mineral deposits and assets in the nation. Silver, gold, copper, phosphorous, molybdenum, and critical minerals such as cobalt, antimony, and rare earths are scattered in abundance throughout our state. Without these minerals, the batteries, wind turbines, solar panels, and grid infrastructure could not be built. The daily demand for these and other minerals continues to rise. As the world population grows and we transition to more renewable energy sources, this demand will go up. The massive increases we will have to see in mineral production to fill all the technological needs of making our nation 100 percent reliant on solar, wind, and battery power are astronomical. This doesn’t include the continued increase in demand for smart phones, computers, tablets, TVs, electric cars, and fertilizers, among other things. Throughout the last year, we have heard policymakers’ continued calls for renewable and green energy and rebuilding infrastructure, while in the next breath calling for mining bans across

the country. These promises and policies are well-meaning, but they fail to connect the dots on how our nation can achieve these clean energy, infrastructure, and manufacturing goals without mining. In fact, these goals will require an increase in production and supply of critical and non-critical minerals exponentially. All said, it seems as if there are now folks on both sides of the aisle starting to recognize the threat that a disrupted supply chain can mean to our economy. It is encouraging to see bi-partisan support for permitting reform and acknowledgment that securing critical minerals should be a priority. A current example of this can be seen in the infrastructure package recently passed out of the Senate. The time seems right for our industry to remind citizens and policymakers alike of the role that mining plays on their daily lives. As policymakers continue to work toward investing in infrastructure and alternative energy sources, we must continue to help them connect the dots. Mining has always been an essential contributor to our nation’s commerce. The time is right to remind people that while providing the materials at the front of most supply chains, we are also creating high-paying, safe jobs in a place with some of the most stringent environmental and labor standards in the world. Mined materials are the foundation in which virtually everything is manufactured or built and the Idaho Mining Association members are ready to help lead in this effort. s

EVENTS

RECAP

18 Mine Idaho

e had another busy year at the Idaho Mining Association. With the ongoing COVID-19 pandemic, we once again had to be flexible with many of our scheduled events. Sadly, it also meant we were unable to hold some of our favorite gatherings, but we look forward to next year in the hopes that we can begin to add some of our events and mine tours back to our calendars. IMA continued to be the voice of mining on the regulatory front as we helped usher H. 239 on the design and construc-

tion of phosphogypsum stacks through the process. The bill created design and construction standards where none were previously in place. It was met with overwhelming support as policymakers agreed with the importance of the environmental protections provided in the legislation. In mid-June, we were up north for a wonderful membership reception in Hayden. We had a packed house at the Bees Knees whiskey bar and a great evening of networking. Thank you to those who helped sponsor that event and the folks at Bees Knees. It is becoming a membership favorite and a must-attend event. In August, we were honored to, once again, host our Federal Congressional Delegation and their staff at our annual Delegation Reception. We had over 80 members and congressional representatives at the Coeur d’Alene Cellars in Coeur d’Alene. Thank you to all those who sponsored and attended this fun annual event. We had the opportunity to sponsor the Lowe Family Farmstead mining sluice and corn maze this fall as well. They estimated that over 100,000 visitors had the opportunity to mine for gems and fossils, as well as trying to find their way through the mining themed corn maze. Another successful day for the industry in Idaho as our event grew substantially

in year two. Over 350 industry representatives filled the Boise Centre in November for our fourth-annual Idaho Mining Conference. I want to thank Governor Little for kicking the day off, and both our outgoing and incoming presidents Luke Russell and Mark Kirby for closing the day out. A huge thank you goes out to our speakers, sponsors, and vendors who help fund a wonderful day, as well as fund the great education initiatives that IMA support. We look forward to an even bigger and better 2022 and hope to see all of you at one or all of these events next year! s

Our mission is to be the leader in safe, productive, and innovative mining solutions.

Information on current and historic mines and exploration can be found on the Mines and Minerals page of the Idaho Geological Survey’s (IGS) newly redesigned website: https://www. idahogeology.org/geologic-resources/ mines-minerals. This year, the IGS updated total historic production for the famous Coeur d’Alene district (Figure 1). From 1884 to 2020, the Silver Valley mines are credited with 1,256,612,343 troy ounces (39,085 metric tons) of silver metal along with 7.8 million metric tons of lead, three million metric tons of zinc, 191,000 metric tons of copper, and significant antimony. Two deep underground mines were active. Hecla’s Lucky Friday mine at Mullan recovered from its two-and-a-half year labor strike and was at full production mining the Gold Hunter vein system from their new No. 4 shaft. The mine implemented new mining techniques and longhole blasting methods and expected to produce about 3.5 million ounces of silver in 2021. At Americas Gold and Silver Corporation’s Galena mine the emphasis was on exploration, funded by last year’s investment by Eric Sprott. Phase 1 ended after

a 120,000-foot drill program, plus ongoing rehabilitation and drift development work. The effort added over 35 percent to the resource and fully replaced reserves. Numerous high-grade intercepts were drilled, with several exploring the productive tetrahedrite-rich Silver Vein below the 5,500-level of the mine. For example, drill hole 55-175A intersected nine feet of 215 oz/ton Ag and 6.4 percent Cu. Legacy mine waste issues in the Silver Valley continue to be addressed through state and federal efforts overseen by the Idaho Department of Environmental Quality (Figure 2). At Murray, New Jersey Mining was drilling additional gold-quartz veins at the Golden Chest mine and planning to increase production. They were also permitting to drill rare earth properties

The year was extremely active for exploration of both precious and base metals as well as critical metals, notably cobalt (Figure 1). The gold price hovered around $1,800 per troy ounce and silver was at $24 per troy ounce for most of the year. There was renewed interest in underground mining and new generative areas and models, as well as processing options. In the Silver Valley, Bunker Hill Mining Corporation evaluated a rapid restart plan for the historic Pb-Zn-Ag mine and conducted a 16-hole drill program along with IP/resistivity surveys. A new entry, Silver Valley Metals, acquired the Ranger-Page project just west of the Bunker Hill, and Silver Hammer Mining Corporation conducted underground drilling at the Silver Strand Au-Ag vein mine near Coeur d’Alene in October. The Stibnite Gold Project in Valley County advanced in the permitting queue, which was extended to allow a supplemental EIS, expected to be out in early 2022. Midas Gold, the owner, changed their name to Perpetua Resources and moved the corporate headquarters to Boise. The Stibnite reserve includes 4.8 million ounces of Au and 148 million pounds of antimony, a critical mineral. Revival Gold drilled 20 diamond

federal level, the current administration has been reviewing the previous administration’s executive orders and putting their stamp on environmental regulations, many of which affect the mining industry. Here at home, in the past year, we have seen the continuation of some rulemaking, rulemaking that has been vacated and rulemaking that may be on the horizon.

In addition, many areas of Idaho have elevated levels of arsenic that occur naturally in the geology, which makes the promulgation of reasonable and enforceable arsenic criteria challenging. At the time of this publication, rulemaking is still underway, with a final deadline for EPA to approve or promulgate criteria by November 2023. IDEQ has introduced proposed draft criteria during recent public meetings. One of the proposed Human Health criteria values would continue the 10 μg/L criterion for Water and Fish Consumption, while the other would comprise an inorganic arsenic criterion of eight micrograms per kilogram (μg/kg) in fish tissue limit for Fish Only Consumption, with an associated water column value of 4.3 μg/L when fish tissue data are not available.

SVL ANALYTICAL CELEBRATES 50 YEARS OF SCIENCE, FAMILY AND MINING

rom geology exploration to mining environmental research compliance, SVL attributes their longevity to hard work and an adaptive mentality. The laboratory may be an unrecognized partner in mine

operations — until something goes wrong. Mining operators count on data of known quality created by scientists who recognize the importance and worth of each individual sample. For 50 years, SVL Analytical (SVL), through tailings breaches, new permit requirements, and remediation plans, has shown up ready to perform in this space. It is that consistency that makes their work trustworthy to the company’s mining clients, says SVL CEO Nan Wilson. SVL started out as an assay lab, serving geologists on large ex-

ploration projects by processing drill core samples and returning timely assay data. By the mid-‘90s, however, the exploration work all but disappeared. “At the time, SVL had 100 employees on staff putting in double shifts to keep up with the workload,” says Wilson.

30 Mine Idaho

“We faced an inevitable crossroad: pivot our focus, or close our doors.” Fortunately, SVL had a strong work relationship with geologists, who found themselves consulting, leading and working in environmental departments at mines around the west. SVL was able to answer needs for permit support, waste rock characterization studies, and groundwater and surface water monitoring. “We expanded the laboratory model to support mining operations in all phases, including pre-permit application, operations, closure, and remediation,” says Wilson. “Recognizing the need for defensible data, we developed a robust data quality system.” In order to stay out front, SVL remains committed to keeping up with the pace of technology. “Today’s scientific process doesn’t look like it used to. In 1972, laboratory work was completely manual, a pen and a notebook, glass pipettes and volumetric glassware, similar to what you likely experienced in chemistry lab in school. Data handling was a chore and validation was difficult,” says Wilson.

IN FOR THE LONG HAUL:

UNIQUE PARTNERSHIP CELEBRATES PROGRESS IN REBUILDING UPPER BLACKFOOT RIVER CUTTHROAT TROUT By William Whelan

en years ago, three phosphate mining companies and two conservation groups looked beyond their history of conflict and launched a bold experiment in collaboration. They committed to work together to develop and fund river restoration projects that benefit Yellowstone cutthroat trout in the watershed of the Upper Blackfoot River in southeast Idaho. They named their group the Upper Blackfoot Confluence (UBC) to highlight the value they placed joining forces for a common goal. The Upper Blackfoot is wild trout country. Cold, nutrient-rich headwater streams flow from forested ridges and high valleys to form the meandering Upper Blackfoot River in the north of Soda Springs. The river is one of the last major strongholds for Yellowstone cutthroat trout in the American West. Unfortunately, the basin’s trout populations have declined in recent decades due to a variety of causes, ranging from bird predation to habitat loss. The Upper Blackfoot is also one of the most important sources of ore for the phosphate mining industry, a source of good jobs and a key driver of the southeast Idaho economy. The region’s mineral reserves are large enough to support the phosphate industry for decades to come. UBC’s mining companies – currently the J.R. Simplot Company, Bayer, and Nutrien – have provided over $2 million in restoration funding over the years. The Trout Unlimited and Idaho Conserva-

tion League have helped develop the restoration projects and advised on priorities. They select projects and review results together. This year, Itafos, which operates mines and the Conda processing facility, joined UBC. Tim Vedder, Conda general manager for Itafos said, “Itafos is pleased to join the Upper Blackfoot Confluence (UBC) group. Since acquiring Conda’s phosphate operations in early 2018, Itafos has been involved in a variety of efforts benefitting both the Upper Blackfoot River and Yellowstone cutthroat trout. Itafos’ affiliation with UBC is an additional positive step towards its goals of protecting the environment and wildlife native to Southeast Idaho.” Over the last decade, the UBC’s partnerships have extended beyond its original members to include landowners, local government and a range of agencies such as the Idaho Department of Fish and Game and the U.S. Forest Service. These partners have far more than doubled UBC’s investments. The partners have now completed a host of projects to create the cold, complex and connected habitat that trout need to survive. They’ve worked with irrigators to improve old irrigation diversions, adding fish passage to historic spawning tributaries. They’ve replaced outdated road culverts that had long been barriers for spawning trout. They’ve restored stream banks to make river channels narrower and deeper to lower water temperature, and

they’ve restored other sections of stream to their original channels. They’ve also planted hundreds of willow trees to shade the water and provide cover for the trout. This year, the UBC partners celebrated signs that the trout are making a strong comeback. The Idaho Department of Fish and Game (IDFG) counted more than 1,800 cutthroat migrating from Blackfoot Reservoir to the headwater streams where they spawn. For the second year in a row, the run far exceeded the fewer than 20 fish that were observed in 2005 to 2006. As recently as 2016, only 204 fish were observed making the migration. Spawning ground surveys confirmed the good news. In June, Trout Unlimited and IDFG found over 250 redds (fish nests) distributed among the historically important spawning tributaries in the Upper Blackfoot, including within several reaches that have undergone recent UBC-funded habitat restoration projects. But the adverse conditions brought on by this year’s long, hot summer brought home the reality that large river restoration requires a sustained effort. By early July, stream flows in the Upper Blackfoot River were about one-third of normal levels. Elevated water temperatures and low flows challenged cutthroat trout, which need cold water to survive. Conditions were particularly hard for this year’s juvenile trout, which will emerge from their gravel bed nests in mid-summer. The summer 2021 underscored the need for UBC’s work. Warren Colyer, Trout Unlimited fish biologist and UBC member, explained,

Alan Prouty of J.R. Simplot Co. and Justin Hayes of Idaho Conservation League explain the origins and goals of the Upper Blackfoot Confluence.

“Our projects build resilience for native Yellowstone cutthroat trout by providing healthy habitats and a way for fish to move within and among them. As stream flows drop and water temperatures increase, the fish become increasingly dependent on healthy habitat refuge areas where they find cool water and cover.” UBC’s largest investment this year is in an ambitious, multi-year project at the Blackfoot River Wildlife Management Area led by the Idaho Department of Fish and Game. The project is designed to help cutthroat trout cope with challenging conditions. New riffles and streambank restoration completed in the last two years are expected to raise the water table in restored reaches. This higher water table means more cool, upwelling water in the streambed, giving trout a break from the heat. IDFG biologist Carson Watkins explained, “Ultimately, the goal is to promote landscape-level resiliency to drought and warmer temperatures by increasing the capacity of the river system to retain water and moderate water temperatures. For cutthroat trout, this will help provide the type of cool thermal refuge they need to survive and complete their life cycle in the face of stressful conditions.” Ten years of collaboration have taught UBC’s members the value of patience, sound science, broad partnerships and building trust over time. The UBC looks forward to more years of working together to make the Upper Blackfoot River a place where trout thrive and where people can continue to make a living from the land. s

SILVER TAKES THE GOLD

ilver Hammer Mining Corp. is proving that Idaho is the place to be for silver exploration. Aiming to become a multimine silver producer, Silver Hammer Mining is a junior resource company with three past-producing mines: the Silver Strand Mine in Idaho and the Eliza Silver Project and Silverton Silver Mine, both in Nevada. According to Morgan Lekstrom, president and CEO, the company employs a three-pronged approach to building value in the company: meaningful acquisitions with resource growth and near-term production potential. Currently, Silver Hammer Mining is focusing on exploring and expanding the Silver Strand Mine located in the Coeur d’Alene Mining District of Idaho, within the same geological rock formation, along the same trend as numerous multi-hundred million ounce silver deposits, including the Sunshine and Lucky Friday Mines. “Those mines extend to depths of 1,800-plus meters, so there’s lots of potential there, given Silver Strand has only ever been mined to depths of 90 meters,” Lekstrom says.

34 Mine Idaho

Lekstrom has worked in the mining industry for nearly 15 years, spending time with companies such as FreeportMcMoRan in Indonesia and Rio Tinto in Mongolia, as well as building a mine in Ghana with Golden Star Resources. With a background in electrical automation, project management and engineering management, in addition to running mining metallurgical projects in the steel industry, Lekstrom confidently took on the role of CEO and president, where he is utilizing his growing team of industry experts in exploration and capital market, while leveraging his extensive mine-building background in executing his vision to create a silver production company. “As someone who has traveled all over the world, I am happy to be working with a company focused on the Western United States, especially in Idaho, given there is a plethora of talent here,” Lekstrom says. “It’s a mine-centric community. Coeur d’Alene has folks that are generational miners, which I find encouraging as someone who has built mines before. There seems to be a lot of support for mining.”

The Silver Strand Mine has tremendous discovery potential, considering the location, the neighbors and the types of rocks. The mine is past-producing down to 90 metres depth, and the historic drill results show that it is not just high-grade silver grade, but also high-grade gold. “Having this gold credit is unique to our site,” Lekstrom says. “It’s not common along the Silver Valley, so being in that Revett formation – the same geological formation as Lucky Friday and Sunshine – suggests to us the potential for significant mineralization both at depth as well as laterally along the 5.5-kilometer strike.” Silver Hammer Mining is the first company ever to consolidate the 5.5-kilometer land package, and the company plans to explore the mineralized zones all the way up to the Burnt Cabin Mine, endeavoring to expand Silver Strand from one single vein that only extended down 90 meters to possibly multiple paralleling veins extending to much greater depths.

“It’s underexplored because of the history of that land package being held by multiple different owners and never being looked at from a holistic perspective,” Lekstrom adds. The company recently initiated its first drilling program at the project using modern technology for an environmentally friendly approach, working with a local contractor who introduced new drilling technology from Canadian company Odessey, which aided in accelerating the permitting process, all while following US Forest Service guidelines and laws. “When we looked at this new drilling technology, we were able to make it so it doesn’t touch the ground; there is no surface disturbance,” Lekstrom explains, adding they were granted drilling permissions within two weeks.

EXCELLON IDAHO GOLD: COMMITTED TO THE GEM STATE By Phil Bandy, Senior Project Manager at Excellon Resources Inc.

Drilling at Oakley.

xcellon Idaho Gold is proud to be an Idaho company. We’re excited to be moving the Kilgore Gold Exploration Project forward in Clark County. We place the highest value on being a responsible member of the communities in which we operate, focusing on the long-term benefits for all stakeholders, including our neighbors in East Idaho. We have a deep curiosity in the natural world and a fascination with the search for metals needed for our future. Our exploration is intensely scientific – we analyze before we act – and we rely on the latest in remote sensing and geophysical techniques. This approach allows us to find and define big deposits in a minimally invasive manner. We want to minimize waste while still creating maximum value. Most importantly, we strive to be better by seeking and accepting new innovations, ideas, and perspectives. In other words, we never say “no” without asking “how.” Kilgore Let’s start in Clark County. Kilgore is a caldera-related, lowsulfidation epithermal gold deposit, geologically comparable to Kinross Gold’s Round Mountain with a sizeable, near surface gold resource of almost one million ounces. We have also identified high-grade, near-surface mineralization in Tertiary volcanics

and the underlying late Cretaceous Aspen formation is open for expansion for additional high-grade gold mineralization. We’re learning more about the deposit setting on a local and regional scale every day in a variety of ways. Re-logging historically drilled core is a key step in enhancing the underlying structural and lithologic framework. We’re also sampling and assaying previously unsampled or unassayed core and using screen metallic assaying to better categorize the distribution and presence of coarse gold – hopefully resulting in higher grades throughout the deposit. We’re currently planning to explore the Kilgore Project for the next three to five years. We’ll drill for higher-grade gold based on new geological modelling from our developing understanding of historical data. While the near surface potential at Kilgore is promising, we’re also looking to define underground resource potential. Our exploration thesis is to demonstrate potential for a three- to fivemillion ounce gold opportunity. As such, in addition to drilling, we’re also planning a regional exploration program, including geophysics, mapping, prospecting, soil geochemistry, and modeling. Once we complete exploration, our goal is to advance Kilgore toward development in the coming years through collaboration with regulators, stakeholders, and the community.

Scree slope at Kilgore.

Oakley We’re also exploring the Oakley gold project in Cassia County in collaboration with Centerra Gold, a mid-tier gold producer, which has an option to buy a 70 percent interest in the project from us. Oakley hosts gold-silver, epithermal hot spring-type mineralization at two targets: Blue Hill Creek and Cold Creek, along with detachment-related gold-silver mineralization at Matrix Creek. Extensive IP/RES geophysics have been conducted and diamond core drilling commenced at the Cold Creek target this year.

Our commitment to Idaho is founded upon the respect, patience and curiosity necessary to sustain a balance of economic development and natural resources stewardship. That commitment guides our progress and inherently relies on open and transparent communication with all interested parties as Kilgore and Oakley progress. Great projects require patience and discipline to advance them at the right pace. In Idaho, we are focused on a responsible step-by-step process that can deliver value to all stakeholders. s

TECHNOLOGY AND THE FUTURE OF FLEET MANAGEMENT By Joe Shoen, Connected Asset Specialist

he influence of technology as it relates to the heavy equipment industry is undeniable, even to the point that these technology advancements are included straight from the OEM. Disruptive influences now become standard options, which can lead to more material moved with greater accuracy and less effort. Who would have thought that flying a drone to measure material movement could also add to a machine’s total lifespan? While technology takes human performance to greater heights, the assets also need to be at peak performance. Many of the decisions made in the past to keep an asset running will not suffice as additional sensors, tolerances, and algorithms demand a different approach. The benefit, of course, is we no longer have to be present on the machine to understand what is happening and what will happen. The downside is we now have to know how a PPPC hydraulic system works along with pulse width sensors, software files, and communication channels such as CANBUSS or J1939. The introduction of technology adds another layer to the already complex landscape of our industry. To properly manage and facilitate these growing production dynamics, we must also address the machine health aspect as well. We are now expected to diagnose, predict, and analyze data in addition to maintaining the responsibilities that come with keeping a fleet moving. This can range from recognizing what is generating and transmitting the data all the way to understanding who and how that data is

consumed. The scenario of needing to understand software and networking along with asset environmental impacts is critical to the success of the next generation of site comprehension. If you have already developed a robust and inclusive PM (preventative maintenance) program you may be head of the curve. Allowing your people and processes to be adaptive to the changing equipment and environment(s) will enable different approaches to stay ahead of certain failures. Items such as a pragmatic inspection program and detailed work order history can prove invaluable when trending failures and focus areas. These are starting points for gaining additional understanding and insights to your fleet and are benchmarks for performance. As you start to introduce technologies, you can trend performance, become focused on what needs attention and make those adjustments before they have a negative impact. The not-so-distant technology future for our industry includes vast advancements in autonomous vehicles and safer operations. The bridge between now and then is already being created with production technologies already in place. Our job as fleet managers is to ensure that the assets are available to meet those increasing needs. The days of being able to ignore an indication of failure are waning, thus the need for more advanced health technologies in combination with an increased focus on prevention of failures. s

INTEGRA DELAMAR: RAISING THE BAR FOR MODERN MINING

By Mark Stockton, Vice President Corporate Affairs & Sustainability at Integra Resources

or generations, the legacy of past mining practices has pitted environmental organizations and mining companies against one another. And that is not without reason – as the follies of historic mining have had large impacts. The sins of mining’s past are a reality that modern miners own. Many in the industry are working hard to build trust, acknowledging that it may take time and proven effort. From day one, our team of dedicated staff began working to advance the Integra DeLamar Project with a serious commitment to environmental stewardship, seeking out opportunities to go beyond what is required. Idahoans have a strong tie to the land. As stewards of a large project, we share that tie and take the responsibility seriously. Where in the past, miners and environmentalists have not seen eye to eye, modern miners aim to learn from history so that future projects are ones that all Idahoans can be proud of. At Integra we firmly commit to raise the bar for modern mining practices. Some of the ways we are currently doing that is by partnering with groups that push us to raise our awareness and performance in sustainable & environmental practice. In 2021, Integra signed a memorandum of understanding (MOU) with Trout Unlimited, a non-profit organization dedicated to the conservation of freshwater fish habitat. Through our partnership, we are evaluating potential future habitat reclamation

40 Mine Idaho

projects surrounding the project area, particularly within the Jordan Creek watershed in Owyhee County. Integra’s partnership will seek to improve some of the damage from antiquated mining practices that impacted Jordan Creek during the late 1800s and early 1900s. Our hope is to find ways to enhance habitat for species like the redband trout. As we continue to advance the DeLamar Project, we are committed to minimizing unnecessary impacts within the project boundaries. Where there are impacts, we will seek opportunities to offset them with positive habitat improvements in surrounding areas. These potential habitat projects could include road crossing improvements, aquatic organism and fish passage barrier identification, reclamation, and revegetation of mining impacted lands, source reduction of mercury from historic mills, and in-stream habitat improvements. Meanwhile, Idaho-based Warm Springs Consulting, a sustainability consulting firm of scientists, engineers, and analysts, committed to finding innovative technologies and sustainable practices that reduce overall environmental impact and improve the bottom line, is working closely alongside our engineering team. Together, they have produced a prefeasibility study (PFS) that looks much different than those of the past. This PFS looks beyond what is required for regulatory compliance and includes technology and renewable energy options that will have the In-

REVIVAL GOLD IS FOR RESPONSIBLE ECONOMIC DEVELOPMENT

odern exploration and development companies such as Revival Gold are increasingly leading the way in responsible economic development, according to Hugh Agro, Revival Gold’s president and CEO. While the public calls for greater employment equality and diversity, coupled with increasing care for environmental considerations such as decarbonization, clean water and a biodiverse environment, mining companies are at the vanguard proving that industry can achieve these goals in addition to delivering the necessary economic benefits derived from modern mining. Revival Gold’s Beartrack-Arnett gold project near Salmon in Lemhi County is an example of this modern and responsible approach to exploration and mining with diversity in employment including female directors and executives, a “safety first” culture and a track record of award-winning reclamation of previous mining activity. Salmon is a small and remote community within which Revival Gold will provide a significant economic impact when BeartrackArnett resumes gold production. With many past and current Beartrack-Arnett employees living in Salmon, the company takes its position within the community seriously. Whenever possible, Revival Gold seeks to engage local businesses and hire locally to provide desirable employment to Salmon’s residents, particularly those who might otherwise have to migrate to larger cities for their livelihood. This approach assists the town of Salmon in maintaining a vibrant community. 44 Mine Idaho

As an example, Salmon resident Lexie Adams-Lett, who previously worked as a flight attendant, returned to school to obtain a geology degree, and was subsequently employed by Revival Gold. Earlier this year, Idaho regional economist Steven Peterson, a long-term associate clinical professor at the University of Idaho, Moscow, Idaho, completed an independent economic study on the potential impact of the Beartrack-Arnett project on the local community of Lemhi County and the State of Idaho. His analysis concluded that the project would provide the following: • $1.2 billion in cumulative contributions to the Idaho State gross domestic product over an eight-year period; • 858 average annual full-time jobs supported during operations including – direct employment of 267 personnel at site – an additional 506 full-time jobs supported during construction; and • $87 million and $121 million of cumulative contribution to state of Idaho and federal tax revenues. “The project could have a substantial positive impact on employment, skills development and overall economic activity that would bring a much needed economic boost directly and indirectly to hundreds of families and local businesses in Idaho. Beartrack-Arnett has the potential to support a peak of more than 1,300 high-wage, full-time jobs representing almost $100 million a year in total compensation, largely in a region that suf-

Revival Gold is not solely focused on economic impacts. The company recognizes there are multiple uses for the public lands on which it operates, and that Revival Gold has a responsibility to conduct its activities safely and with care and consideration for the environment and other users. The Beartrack-Arnett project benefits from considerable existing infrastructure including roads, hydro powerlines and buildings. The company is reusing an idled plant-site, in effect, recycling existing infrastructure, which might otherwise be put to waste. The project benefits from the availability of hydroelectric power in Idaho. Hydropower will allow Revival Gold to produce gold with a lower carbon footprint and lower emissions than other gold mining projects in the U.S. The company will continue with Beartrack-Arnett’s award-winning track record of reclamation, to return any areas disturbed by mining to a natural state for future generations to enjoy. The company also supports local initiatives including the Salmon Hockey Association, the Lemhi County Fair, 4-H Youth Development and food banks. Revival Gold’s goal is to bring Beartrack-Arnett back into production, as it was Idaho’s largest gold producer when it operated

in the 1990s. The mine was shut down in the early 2000s when the gold price was below $300 per ounce. In November 2020, the company released a preliminary economic assessment that would result in an average of 72,000 ounces of gold production annually for an initial mine life of seven years. Currently the company is conducting an extensive exploration program to discover additional resources and potentially extend the mine life. An extension of the project life would result in further economic and social benefits for Lemhi County, Idaho and its residents. With three and a half miles of favourable mineralized structure across Revival Gold’s 14,300-acre land position, the Company has tremendous exploration upside beyond its current three-million ounces of gold in resource. The Joss target at Beartrack-Arnett is an exciting aspect because it contains higher grades of gold. The Company is also drilling to upgrade and expand resources at its Haidee target area. “The next 12 months promise to be exciting ones for our team and the community of Salmon, Idaho, as we release results from exploration drilling, additional metallurgical test work and optimization efforts focused on responsibly guiding Beartrack-Arnett back into production,” said Agro.

This makes recovering antimony from site economically feasible and provides Perpetua Resources the funds necessary to restore what is currently an abandoned brownfields site. The U.S. Forest Service is currently evaluating the Stibnite Gold Project under the National Environmental Policy Act (NEPA). The Forest Service is expected to release a Supplemental Draft Environmental Impact Statement (SDEIS) for public review in Q1 of 2022, after the company submitted additional improvements to its plan in December 2020. After listening to stakeholder feedback and collecting more data, Perpetua Resources found new ways to reduce the project footprint and improve water quality and temperature on site, while still responsibly producing the critical mineral antimony American’s so desperately need. A final record of decision on the project is expected in the first half of 2023. s

IDAHO MINING CONFERENCE SUMMARY By D. Kerner

n November 1 and 2, 2021, in Boise, Idaho, 350-plus representatives from Idaho’s mining and related industries

breathed a collective sigh of relief at the reinstatement of the in-person format for the Idaho Mining Association’s fourthannual Idaho Mining Conference. The latest iteration of this ever-growing event returned to its original platform this year and boasted a larger and more accessible downtown venue, an added day for registration, vendor set-up and meetings, and an expanded suite of technical sessions. Individuals from all corners of the state gathered at the Boise Center to share information, engage in camaraderie, and re-calibrate an industry that, like other areas of essential services, doesn’t have the luxury of taking days off during the COVID pandemic. The robust response from everyone that sponsored, attended and engaged in the IMC sent a resounding message: the people of this industry are what matter, and their coming together is an important part of the mission to conduct responsible mining in Idaho. Together with its growing membership and event participants, the Idaho Mining Association’s annual flagship event is charting the course for Idaho’s miners, explorers, and would-be operators; positioning itself as a leader for the state’s mineral industry; and a source for encouraging broader understanding of what’s to come. And the timing is right. The future seems now to be more complicated than ever: How will ever-changing regulatory frameworks impact our capability to provide the minerals that the United States and global economies demand?

54 Mine Idaho

What can we, as an industry and a nation, do to continue to lead in the areas of environmental responsibility and social governance? How do we effectively communicate our industry’s integral role in national security when looked at through the broader lens of domestic mineral production and the foreign import reliance? The Idaho Mining Conference certainly is effective in stoking enthusiasm and energy, and it also challenges us all by bringing these hard-hitting questions and topics to the fore and encouraging us to find solutions. To set the tone of the conference, Idaho Governor Brad Little’s opening statements included an endorsement of Idaho mining’s contributions to the Gem State’s overall business climate, “We’re partners in creating this incredible miracle that’s taking place here in Idaho. I am very bullish. If I had the opportunity to buy stock in any of the 50 states, I’d really go long on buying stock in Idaho, because of what all of you have done.” High praise from the Governor, and what’s not to love? In a 2020 annual survey conducted by the Fraser Institute in Canada, mining and exploration companies’ ratings of 77 mining jurisdictions ranked Idaho first for policy perception and ninth when mineral potential was considered. As the technical sessions got underway, important updates on operations, permitting, exploration, and environmental issues were punctuated by the addition of new topics and panel discussions that are likely to become perennial mainstays. The Critical Minerals session will become increasingly pertinent in coming years as two critical mineral resource projects in Idaho (Iron Creek – First Cobalt [cobalt] and Stibnite – Perpetua Resources [antimony]) advance toward production. With current U.S. import reliance at 76 percent for cobalt and 81 percent for antimony, the implications of developing these resources in Idaho would be a boon for national supply-chain security, not to mention the

ronment, social, and governance (ESG) principles, or understand how quickly they are becoming necessary principles to attract investment in this modern age, you’d do well to become acquainted. The Net Impact Panel, moderated by Josh Serfass (Integra Resources Corp.) with participating panelists Amber Bieg (Sprout Energy & Warm Springs Consulting), Jason Willis (Trout Unlimited), Kevin Carter (Cormark Securities) and Mckinsey Lyon (Perpetua Resources), provided a nice primer on the topic.

We’re Hecla Mining Company. More than a third of all the silver produced in the United States today comes from Hecla. The same company that holds the nation’s largest silver reserve and resource. The same company whose innovative mining practices are protecting both the environment and the safety of its workers. The same company that got its start 130 years ago — right here in North Idaho’s fabled Silver Valley. hecla-mining.com

THE FUTURE STARTS HERE. Responsible production of critical resources begins right here at home. At Perpetua Resources, we are proud to be developing the nation's only source of mined antimony.
