Investor Insight
With a mining lease application underway and a scoping study that shows excellent economics, Impact Minerals’ game-changing, advanced Lake Hope high-purity alumina project makes for a compelling investment case.
Overview
Impact Minerals (ASX:IPT) is an exploration and development mining company focused on discovering and developing new resource projects within Australia. Lake Hope, a transformational acquisition by the company and its current flagship asset, is a high-purity alumina (HPA) project in Impact’s home territory of Western Australia, a tier-one jurisdiction.
This advanced-stage project allows the company to fast-track the asset toward development, firmly establishing the company on the road to production and increasing shareholder value.
HPA is a high-value product with various uses in several industries that are key to the transition to a low-carbon world. It is mainly used in LED lighting, micro-LED screens, and ceramic-coated separators in lithium-ion batteries. Both these markets are forecast to grow dramatically over the next decade, and a looming supply shortage is predicted for 2026.
HPA is also necessary for producing synthetic sapphire and scratch-resistant glass. With these ever-widening applications for HPA, demand for this resource is expected to grow from US$3.18 billion to US$12.21 billion by 2030 with a compounded annual growth rate of about 20 percent.
Lake Hope is the company’s current focus as it moves towards production, and where a very shallow, high-grade resource of HPA precursor material has been identified in the top two meters of a dry salt lake. The deposit has unique physical and chemical properties that will allow for inexpensive digging and mining, with transportation to a processing facility off-site in an established industrial area. This will accelerate the approvals processes required to get into production.
With a mining lease application pending, Impact aims to bring Lake Hope, which contains almost 1 million tons of potential HPA, into production when the forecast average price for 4N HPA (99.99 percent Al2O3) and related products is about US$20,000 per ton. The ‘4N’ designation indicates the purity grade, making it suitable for high-tech end uses.
Outstanding economics from the latest scoping study released by the company shows Lake Hope’s potential to be the lowest-cost producer of HPA globally by up to 50 percent.
Lake Hope has a maiden mineral resource estimate (MRE) of 3.5 million tons at 25.1 percent alumina (Al2O3) for a contained 880,000 tons of alumina. The company also received heritage clearances for the entire Lake Hope deposit further de-risking the project and providing another critical component in the company’s application for a mining lease.
Impact completed a bulk sampling and test pits program at the Lake Hope project in December 2023, and later reached a key milestone by producing HPA greater than 99.99 percent (4N) purity from the metallurgical processing of lake clays acquired from Lake Hope.
In February 2024, a new proprietary metallurgical process for producing HPA from the lake clays was identified. Impact produced 99.99 percent (4N) Al2O3 from a low-temperature leach (LTL) process. The LTL process may lower the capital and operating costs to produce HPA compared to the sulphate process which underpinned the recent scoping study. The LTL process will be included in the ongoing pre-feasibility study in parallel with the sulphate process at marginal extra cost to determine the best processing route to HPA. The PFS is due to be completed in late 2024.
A comparison of the LTL process and the sulphate process
The company is well funded to finance the pre-feasibility study at the Lake Hope High Purity Alumina project and exploration activities at the Arkun battery minerals project.
Impact Minerals has been awarded a $2.87 million grant for the commercialisation of its innovative process to produce High Purity Alumina (HPA) from the Lake Hope deposit. The grant is under the Federal Government’s Cooperative Research Centres Projects (CRC-P) program which fosters short-term, industry-led research collaborations. The grant is part of an estimated $6.4 million research and development project to be completed within three years and designed to provide Impact with the relevant information required to complete a definitive feasibility. A key component of the grant funding will be to construct a pilot plant, which is a key goal for 2025, and this will provide consistent material for off-take and qualification trials.
Impact Minerals was also one of the inaugural cohort of seven companies selected to be part of the prestigious BHP Xplor program. BHP Xplor, an accelerator program introduced by BHP in August 2022, is designed to help provide participants with the opportunity to accelerate their growth and the potential to establish a long-term partnership with BHP and its global network of partners.
The BHP Xplor funding was used to identify new target areas for copper and other energy metals around the Broken Hill area in New South Wales, eastern Australia, where Impact has been quietly adding to its ground position for several years.
Additionally, the company is exploring its large Arkun battery metals project, also in Western Australia which covers nearly 2,900 square kilometres. Three new exploration licence applications were submitted recently immediately north of the Arkun project along trend from the recently discovered REE soil geochemistry anomalies at Hyperion, Swordfish and Horseshoe, and the Caligula copper anomaly. These anomalies require drill testing which will occur in 2024 and is an exciting development in the emerging mineral province of southwest WA.
A strong management team with over 50 years of combined industry experience leads the company. With a mining and exploration geology degree, Dr. Mike Jones, managing director, launched a long career consulting and leading mining organizations. Peter Unsworth, the non-executive chairman, has more than 35 years of experience in multiple financial sectors, such as securities industries and wealth management. Paul Ingram, a non-executive director, has led several mining companies since 2003. Impact Minerals has the experience and expertise to lead the company to success.

Key Projects
Lake Hope HPA Project
Impact Minerals’ Lake Hope HPA project is in Western Australia, a tier-one mining jurisdiction. HPA is a crucial component in many new and emerging technologies, creating ongoing demand for high-grade sources. The Lake Hope project is the company’s flagship as it moves toward production.
Project Highlights:
- Maiden Mineral Resource Estimate: A maiden mineral resource of 3.5 million tonnes at 25.1 percent alumina (Al2O3) for a contained 880,000 tonnes of alumina has been defined at the Lake Hope HPA Project. About 88 percent of the resource, or 775,000 tonnes of alumina, is in the higher confidence indicated resource category.
- Amenable to Open-pit Mining: The Lake Hope project is a unique HPA asset amenable to shallow, open-pit mining. The deposit is soft and shallow, allowing for cheap digging and minimal infrastructure requirements. This type of deposit also lowers the environmental footprint of the operation.
- Fast-tracked to Production: A mining lease application is currently underway. Once granted, the company will begin working towards a pre-feasibility study and mini pilot plant. Impact Minerals plans to reach a complete pilot plant by 2026.
- Impressive Results of the 2023 Scoping Study: Outstanding economics show Lake Hope to potentially be the lowest-cost producer of High Purity Alumina (HPA) globally by up to 50 percent. Key outcomes from the scoping study include:
- Annual production of 10,000 tpa of 4N HPA with an initial 25-year mine life
- Annual EBITDA of A$174 million.
- 2 years construction period with 5,000 tonnes of production during the first year, 8,000 tonnes in the second year and 10,000 tonnes of production thereafter.
- US$934 million post-tax NPV8 at an IRR of 55 percent.
- Mining Lease Application: Amining lease application was lodged in mid-2024 over the West Lake resource while a miscellaneous licence application (L63/99) was lodged to cover mine infrastructure and haulage road.
The scoping study was underpinned by a sulphuric acid process allowing the company to achieve a new milestone by producing HPA with purity of more than than 99.99 percent (4N) from the metallurgical processing of lake clays acquired from Lake Hope. The company further identified a new proprietary metallurgical process for producing HPA from the lake clays. Known as the low-temperature leach (LTL) process, this also produced 99.99 percent (4N) Al2O3 and has the potential to lower even further the capital and operating costs to produce HPA compared to the sulphate process. The LTL process will be included in the ongoing pre-feasibility study along with the sulphate process to determine the best processing route to HPA. The PFS is due to be completed in late 2024.
Broken Hill Copper Project
The Broken Hill project has a significant land position of 815 square kilometers and hosts multiple targets with the potential for high-grade copper. Broken Hill is located in New South Wales, Australia, an area known for its prolific silver-lead-zinc mining operations and the giant Broken Hill deposit.
Project Highlights:
- Participant in the BHP Xplor Program: Impact was selected for the BHP Xplor program in 2023 based on its Broken Hill project. The program is designed to allow participants to accelerate growth and establish a long-term partnership with BHP.
- Potential for Additional Minerals and Deposits: As well as copper, the project has significant exploration potential for magmatic nickel-copper-PGE sulphides, and at the time the host rocks were formed, Broken Hill was located close to the world-class nickel-copper-PGE deposit of Jinchuan and the significant Lengquisheng deposit. The project area also has the potential to contain zinc-lead-silver deposits, providing even more value.
Arkun Nickel-Copper-Gold-Lithium-REE Project
The Arkun project is a 2,900-square-kilometer nickel, copper and gold project located in the emerging Ni-Cu-PGE province near the world-class Julimar Ni-Cu-PGE deposit and surrounded by Anglo American Corporation, which secured its ground holding shortly after Impact secured its asset. Anglo-American is one of the world’s top ten mining companies, and their presence in the region brings confidence in the project’s potential.
Project Highlights:
- Additional Exploration Underway: Impact plans follow-up work programs, including drilling, at its priority targets.
- Significant Targets Identified: Recent soil sampling identified two new prospects:
- Hyperion prospect - Located in the northwestern part of the project area returned with rare earth element anomalism of up to 5,880 ppm (0.59 percent) total rare earth oxide (TREO+Y) and neodymium and praseodymium (Nd+Pr) of up to 21 percent.
- Caligula prospect - Initially identified on the roadside, the Caligula prospect is a large and significant target for porphyry copper mineralisation.
- Three New Exploration Licences: Impact applied for three new exploration licences expanding Arkun project along trend from the recently discovered REE soil geochemistry anomalies at Hyperion, Swordfish and Horseshoe as well as the Caligula copper anomaly.

Lahontan Gold Announces Positive Preliminary Economic Assessment for Santa Fe
Lahontan Gold Corp. (TSXV:LG)(OTCQB:LGCXF)(the "Company" or "Lahontan") is pleased to announce results from a positive Preliminary Economic Assessment(" PEA") on its flagship Santa Fe Mine gold-silver project located in Nevada's prolific Walker Lane Trend. The PEA was prepared by Kappes, Cassiday & Associates ("KCA") of Reno, Nevada with mine planning and production scheduling contributions from RESPEC Company LLC ("Respec"), Reno, Nevada and mineral resource estimation by Equity Exploration Consultants Ltd. ("Equity"), of Vancouver, British Columbia, in accordance with Canadian National Instrument 43-101, Standards of Disclosure for Mineral Projects ("NI 43-101").
PEA Highlights:
- Pre-tax Net Present Value at a 5% discount rate ("NPV5") of US$265.1 M with a 41.0% IRRwith an After-tax NPV5 of US$200.0 M with a 34.2% IRR utilizing a $2,705/oz gold price and a $32.60/oz silver price ("spot metal prices") (see spot metal price to base case metal price comparison in Table 1).
- Total Life-of-Mine ("LOM") Pre-tax net cash flow of US$373.3 M and After-tax net cash flow of US$288.9 M over a nine-year project life using spot metal prices.
- Total projected LOM revenue of US$930.8 M over a nine-year project life using spot metal prices.
- LOM strip ratio of only 1.54 (waste to mineralized material ratio).
- Estimated pre-production capital costs of US$135.1 M including a 20% contingency, with a payback of 2.9 years using spot metal prices.
Kimberly Ann, Lahontan Gold Corp Executive Chair, CEO, President, and Founder commented: "Lahontan is very excited about the results of the PEA: a low-capex, highly profitable mining project with a quick payback certainly bodes well for the future of Lahontan and all stakeholders. There is considerable potential to expand gold and silver resources, therefore this is just the first step in restarting mining operations at Santa Fe. With mine permitting well under-way, targeting a 2026 mine ground-breaking, the potential for the Company to realize the economic outcomes outlined in the PEA is very real, especially given current trends in gold and silver prices. Continued optimization of the mine plan, resource expansion drilling, and refining the metallurgical flow sheet are planned for 2025, in parallel with our permitting activities."
The PEA is preliminary in nature, includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The Company has not defined any Mineral Reserves at the Santa Fe Mine project.

Mine Production Schedule
The PEA mine production schedule includes mining of leach material and waste for the Santa Fe, Calvada, Slab, and York deposits. Leach material was assumed to be sent to a centralized crushing plant and then stacked on a leach pad and the waste material was sent to designed waste rock storage facilities (WRSF) or used as partial backfill into the Calvada pit.
Because the Santa Fe Mine is a brown-field project, minimal pre-stripping is required to develop sufficient stockpiles to feed the crusher. The mine production schedule requires 2 months of preproduction which begins in the Santa Fe deposit. The Calvada deposit is started in year 2 and mined concurrently with Santa Fe. Calvada mining is followed by mining of Slab and York deposits.
The process schedule was developed with a ramp up of production from year 1 through year 3 to a full 4.56 million tonnes per year. Table 4 shows the process production schedule.

Mining and Processing
The mineralized material will be mined by standard open-pit mining methods using a contractor-owned and operated mining fleet consisting of 92-tonne haul trucks and 11.5-m3 loading units and transported to the crushing circuit for processing.
Mineralized material from the Santa Fe, Calvada, Slab and York deposits will be processed by conventional heap leaching methods. The nominal processing rate will be 4.6 million tonnes per annum or 12,500 tonnes per day. Three-stage crushing of the material to 12.7 mm, will be followed by conveyor stacking on to a multi-lift heap leach pad. Dilute sodium cyanide solution will be applied to the heap, with the pregnant gold and silver-bearing solution effluent from the heap being processed in a carbon adsorption-desorption-recovery (ADR) plant. Gold and silver will be produced in the form of doré bars from the on-site smelting process.
Mineral Resource Estimation
The mineral resource estimate ("MRE") was prepared in accordance with the CIM Definition Standards and Canadian National Instrument NI-43-101. The effective date of the MRE prepared by Equity is October 9, 2024. The MRE is shown in Table 6.
Table 6: Project-wide Resources, Santa Fe Mine, Mineral County, Nevada
Notes to Table 6:
- Mineral Resources have an effective date of October 9, 2024. The Mineral Resource Estimate for the Santa Fe Mine was prepared by Trevor Rabb, P.Geo., of Equity Exploration Consultants Ltd., an independent Qualified Person as defined by NI 43-101.
- Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Inferred Resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be classified as Mineral Reserves. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
- Resources are reported in accordance with NI43-101 Standards of Disclosure for Mineral Projects (BCSC, 2016) and the CIM Definition Standards for Mineral Resources and Mineral Reserves (CIM, 2014).
- Mineral Resources were estimated for gold, silver, and gold equivalent (Au Eq) using a combination of ordinary kriging and inverse distance cubed within grade shell domains.
- Mineral resources are reported using a cut-off grade of 0.15 g/t Au Eq for oxide resources and 0.60 g/t Au Eq for non-oxide resources. Au Eq for the purpose of cut-off grade and reporting the Mineral Resources is based on the following assumptions gold price of US$1,950/oz gold, silver price of US$23.50/oz silver, and oxide gold recoveries ranging from 45% to 79%, oxide silver recoveries ranging from 10% to 30%, and non-oxide gold and silver recoveries of 71%, mining costs for resource and waste of US$2.50/t, processing cost (oxide) US$3.49/t, processing cost (non-oxide) US$25/t.
- An optimized open-pit shell was used to constrain the Mineral Resource and was generated using Lerchs-Grossman algorithm utilizing the following parameters: gold price of US$1,950/oz gold, silver price of US$23.50/oz silver, and selling costs of US$29.25/oz gold. Mining costs for resource and waste of US$2.50/t, processing cost (oxide) US$3.49/t, processing cost (non-oxide) US$25/t, G&A cost US$1.06/t. Royalties for the Slab, York and Calvada deposits are 1.25%, and maximum pit slope angles of 50 degrees.
- Totals may not sum due to rounding.
Estimation Approach: Lithology and gold and silver bearing domains were modelled using Leapfrog 2024. These domains are mainly defined by logged jasperoid and limestone-breccia lithologies and continuity of gold grades above 0.1 g/t gold. Metallurgical domains for oxide, transition and non-oxide were modelled based on ratio of cyanide leachable gold assay values to fire assay gold values in addition to drillhole logs recording abundance of pyrite and oxidation intensity. Transition material represents approximately 35% of oxide tonnes and comes almost entirely from the Santa Fe deposit. Transition domain material is included in the oxide resource. Domains representing lithology, weathering and mineralization models were assigned to a block model with a block size of 5 m x 5 m x 6 m. Average bulk densities representative of the mineralization and lithology models were assigned to the block model and vary from 2.4 t/m3 to 2.6 t/m3.
Grade capping and outlier restrictions were applied to gold and silver values and interpolation parameters respectively. Top cut values for gold and silver were evaluated for each domain independently prior to compositing to 1.52 m lengths that honor domain boundaries. Estimation was completed using Micromine Origin with Ordinary Kriging (OK) and Inverse Distance cubed (ID3) interpolants. Blocks were classified in accordance with the 2014 CIM Definition Standards. The nominal drillhole spacing for Indicated Mineral Resources is 50 m or less. The nominal drillhole spacing for Inferred Mineral Resources is 100 m or less.
Prospects for eventual economic extraction were evaluated by performing pit optimization using Lerchs-Grossman algorithm with the following parameters: gold price of US$1,950/oz gold, silver price of US$23.50/oz silver, selling costs of US$29.25/oz gold. Mining costs for resource and waste of US$2.50/t, processing cost (oxide) US$3.49/t, processing cost (non-oxide) US$25/t, G&A cost US$1.06/t. Royalties for the Slab, York and Calvada deposits are 1.25%. Maximum pit slope is 50 degrees. Processing recoveries range from 45% to 79% for oxide, silver recoveries range from 10% to 30% for oxide and non-oxide gold and silver recoveries are 71%.

Gold Price 2024 Year-End Review
Read on for more on what factors moved the gold price in Q4, followed by a look back at the entire year.
Gold price in Q4
The gold price began Q4 at US$2,660.30, but quickly saw a retraction to US$2,608.40 on October 9. However, the decline didn't last, and gold again rose, setting a new record high of US$2,785.40 on October 30.
The surge upward was fueled by a weaker-than-expected September US consumer price index report, which showed annual inflation of 2.4 percent and monthly inflation of 0.2 percent. These numbers were higher than analysts' forecasts of 2.3 and 0.1 percent, raising expectations that the Fed would cut rates at its November meeting.
Gold was in retreat to start November, dropping to US$2,664 on November 6 after Trump’s victory. The next day, it briefly surged above the US$2,700 mark as the Fed cut interest rates by 25 basis points on November 7.
By November 15, the price of gold had fallen to its quarterly low of US$2,562.50.
The end of the month saw gold leap to US$2,715.80 on November 22. Following this peak, gold entered December below the US$2,700 mark, closing at US$2,660.50 on December 9.

Geopolitical impacts have been important to gold in Q4.
In addition to Trump's re-election, which has caused turmoil in various forms, on November 17 the US authorized Ukraine to use ATACMS long-range missiles to attack targets deeper into Russian territory. The UK and France mirrored this move, giving Ukraine the green light to use long-range missiles in the ongoing conflict.
Tensions continued to ratchet up in the days following as Russia announced it was lowering the threshold for nuclear retaliation to include conventional attacks from countries backed by nuclear nations. In a demonstration of its capabilities, Russia launched an intermediate-range ballistic missile for the first time on November 21. While the missile appeared only to carry inert warheads, it is capable of delivering both conventional and nuclear armaments.
The threat of a significant escalation has bolstered gold’s appeal as a safe-haven asset and store of value.
How did gold perform for the rest of the year?
Gold price in Q1
Gold set its first record price of the year at US$2,251.37 on March 31.
Central bank buying, notably China's purchase of 22 metric tons of gold in the first two months of the year, supported the price. Turkey, Kazakhstan and India also significantly increased their holdings at the start of the year.
Further momentum came from Chinese wholesale demand, which jumped to 271 metric tons in January, the strongest ever recorded. Investors were turning to the yellow metal as a defense against falling real estate and stock prices. At that time, the country's stocks had lost nearly US$5 trillion in value over the past three years.

“As central banks continue to be significant buyers and geopolitical risks and global uncertainties drive investors towards the perceived safety of gold, the current environment underscores gold’s importance as a strategic asset for portfolio diversification and risk mitigation. Therefore, while there may have been a perception of western disinterest in gold, recent developments indicate a sustained and broad-based demand for the precious metal,” Joe Cavatoni, market strategist, Americas, told the Investing News Network (INN) in an email at the time.
Gold price in Q2
The gold price saw increasing momentum in Q2, setting a new all-time of US$2,450.05 on May 20.
Gains through the quarter were influenced by strong central bank demand. Investor sentiment toward the yellow metal also shifted, with outflows from western exchange-traded funds starting to slow.
Although European funds still saw significant declines, it wasn’t all bad news — the US-based SPDR Gold Shares (NYSE:GLD), the Sprott Physical Gold Trust (NYSE:PHYS), Ireland’s Royal Mint Responsibly Sourced Physical Gold ETC (LSE:RMAU) and Switzerland’s UBS ETF Gold (SWX:AUUSI) all saw increases.

In a May interview with INN, Jeff Clark, editor of Paydirt Prospector, noted several other market dynamics that caused the price of gold to rise dramatically. He said the real starting point for the precious metal's gains was the end of February, when the Fed indicated it was expecting three or four rate cuts in 2024.
“All of a sudden, gold was off to the races. It jumped so high that suddenly, you had some short covering that needed to happen then as well. So you had short covering, which means they’re buying. And then you had momentum chasers and traders jumping all in. That was a pretty good spike ... that's what kind of started all of this,” he said.
Gold price in Q3
Gold set another record price during the third quarter, reaching US$2,672.51 on September 26.
The high came just a week after the conclusion of the Fed's September meeting, when it announced a jumbo 50 basis point cut to the federal funds rate. While the People’s Bank of China maintained its pause on gold purchases in the third quarter, it granted several regional banks new import quotas in August.

David Barrett, CEO of the UK division of global brokerage firm EBC Financial Group, suggested at the time that Fed rate cuts were less of a factor for gold than central bank buying. “I still see the global central bank buying as the main driver — as it has been over the last 15 years. This demand removes supply from the market. They are the ultimate buy-and-hold participants and have been buying massive amounts,” he told INN via email.
The quarter also saw significant merger and acquisition activity, with South Africa-based Gold Fields (NYSE:GFI,JSE:GFI) announcing plans to acquire Canada’s Osisko Mining (TSX:OSK) for C$2.16 billion, and South African gold miner AngloGold Ashanti (NYSE:AU) agreeing to purchase UK-based Centamin (TSX:CEE,LSE:CEY) for US$2.5 billion.
Investor takeaway
Overall, uncertainty has been a key driver for gold in 2024.
Central banks have continued to increase their physical holdings against an increasingly polarized political landscape. The most recent data from the World Gold Council shows that they added 186 metric tons of gold to their coffers during the third quarter, with the National Bank of Poland leading the way with 42 metric tons.
The World Gold Council notes that on a rolling four-quarter basis, central bank buying has slowed to 909 metric tons — that's compared to 1,215 metric tons one year ago.
Investors also began returning to the precious metal throughout 2024 as geopolitical tensions and fragile economies pushed them toward gold as a safe haven to help shield their portfolios from volatility.
With the world’s largest economy set to welcome Trump back to the White House in 2025, there are many unknowns. His economic policies could cause inflation to begin creeping up. In contrast, his foreign policies could create new ripples through global trade and financial markets given that he campaigned on more protectionist policies.
