A large and significant target for porphyry copper-gold mineralisation has been identified at Impact Minerals Limited’s (ASX:IPT) 100% owned Arkun Project located 150 km east of Perth in the emerging mineral province of southwest Western Australia (Figure 1).
- A large and significant target for porphyry copper mineralisation has been identified in soil geochemistry data and Mobile Magneto-Telluric (MMT) data at the Caligula Prospect.
- A 5 km by 1 km soil geochemistry anomaly contains the key metal assemblage of copper- silver-cobalt+/-tellurium-bismuth-molybdenum, all indicators of porphyry copper mineralisation such as is found at Boddington and Calingiri in the same region of Western Australia. Gold assays are expected in February.
- The geochemistry anomaly coincides with numerous conductors identified in the MMT data that may represent disseminated or massive sulphides.
- Infill and extensional soil geochemistry surveys, together with a detailed interpretation of the MMT data, are underway to define the extent of Caligula and identify specific drill targets more fully.
- A follow-up aircore drill programme is to be undertaken as soon as practicable, which will also include the recently discovered Hyperion and Swordfish REE prospects.
The newly named Caligula prospect, initially identified in roadside and subsequent follow-up soil geochemistry surveys (Anomaly D: ASX Release 9th August 2023), has been significantly enhanced by the presence of several significant conductors within the geochemistry anomaly that may represent disseminated or massive sulphides.
The conductors were identified in recently acquired helicopter-borne Mobile Magneto-Telluric (MMT) data from one of the first surveys of this cutting-edge technology to be flown in Australia.
Caligula adds to Impact’s previously reported large Rare Earth Element soil geochemistry anomalies identified at Hyperion, located 15 km to the west, and Horseshoe, located 20 km to the east, and emphasises the significant exploration potential for a range of battery and strategic metals at the Arkun project (Figure 4 and ASX Releases 4th January 2024 and 1st June 2023).
Impact Minerals’ Managing Director, Dr Mike Jones, said, “The discovery of the Caligula Prospect is yet another significant and exciting breakthrough in our exploration at Arkun following the recent discovery of the Hyperion and Swordfish Rare Earth Element Prospects. It is one of the first of the many geochemical and geophysical targets we have at the project where we have actually been able to define the size and scale of the anomalies more fully and, given we have at least a dozen more similar areas to follow up, I am confident of more significant anomalies to come at Arkun. We are working towards a maiden drill programme as quickly as possible, and we will aim to cover as many targets as possible, including Hyperion and Swordfish. We are very encouraged by our results so far.”

Soil Geochemistry Results
The soil geochemistry results have defined an area of anomalous copper-in-soils that extends over about 5,000 metres north-south and up to at least 2,000 metres east-west. It is open to the east and the southwest (Figure 2 and Figure 4). The copper is associated with anomalous silver and cobalt and, in the southern part of the anomaly, also has a strong association with bismuth, tellurium and lesser molybdenum (Figure 2). Maximum and minimum values for the metals are given in Table 1.
This metal assemblage is characteristic of metals associated with porphyry copper deposits and this is encouraging for future exploration.

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.

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.
Gold price, Q2 2024.
Chart via Trading Economics.
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.
Gold price, Q3 2024.
Chart via Trading Economics.
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.
