High Resolution Ground Magnetics Commences at 100% - Owned Kiabye Gold Project, Western Australia
HIGHLIGHTS
- Survey has launched today in the northern Kiabye area – an area which has previously reported anomalous gold-in-soil
- Kiabye Gold Project covers 23km2 of strike and remains underexplored – providing considerable upside potential for RMX
- The survey will target structures amenable to gold bearing fluids with target areas to be followed up with detailed pXRF assaying
- The program will take approximately 12 days, covering to 10km2 – results of the magnetic survey are anticipated in mid to late March
- Defined anomalous areas will be targeted for wet chemistry sampling with lab results expected in late March.
The program is focused on the most northern section of the Kiabye licence (E59/2893), which is one of the four exploration licenses that make up the project area. This straddles the Kiabye Greenstone Belt in the Yilgarn‘s Murchison Domain, southeast of Mount Magnet. The survey will total 10km2 and will be split into three areas of focus, based on priority (see Figure 1).
The program is expected to take 12 days, with coverage to depend on the rate of surveying, across both magnetics and pXRF assay follow-up. This will assist the Company in defining the three target areas, based on sample results (see Figure 2). A summary of each area is as follows:
- Area 1 covers a number of anomalous gold in soil samples, hosts two NNE (North- North-East) striking faults and is located in an area of unverified alluvial and insitu gold.
- Area 2 contains numerous gold in soil samples with several samples of >20ppb to 47ppb Au. The block is also cut by two faults striking NNE and NS. The area also contains RMX rock sample KPR020 which assayed at 96ppbAu and 2.6ppm Ag.
- Area 3 contains two areas with samples of >20ppb Au. The west is cut by a major NNW to NS faults marking the boundary between the Kiabye Greenstone Belt and Granites to the west. The second fault strikes NNE and is believed to extend north into Area 2.
Significance of Gold-in soils
In consideration of the highly diluting soil profile in the area, any soil sample with ≥20ppB Au is considered anomalous therefore Area 2 and 3 contain several areas with anomalous gold-in-soils.
Ground Magnetic Survey
The Red Mountain Mining team and contractors will conduct the geophysical survey initially at 100m east - west line spacing and 20m reading intervals. The data will be processed and interpreted in the field and where structures of interest are identifying these areas will be infilled to 50m line spacing. The main targets for gold mineralisation include shear zones and faults interpreted in the data. The surveys will collect data from 110 to 213-line kilometers depending on the number of infill lines conducted.

Lahontan Gold Corp.
Investor Insight
Lahontan Gold is on track to become a leading gold developer in Nevada’s Walker Lane district, presenting a compelling investment opportunity by combining a high-quality resource base with a clear path to production in Nevada’s premier mining jurisdiction — all in a rising gold price environment.
Overview
Lahontan Gold (TSXV:LG,OTCQB:LGCXF) is focused on advancing its portfolio of high-quality gold and silver projects in Nevada. The company’s flagship Santa Fe mine was a past producer that operated from 1988 to 1992, yielding 356,000 ounces of gold and 784,000 ounces of silver. Lahontan aims to unlock the mine’s full potential by expanding its resources and pushing forward on permitting.
The company recently completed a robust preliminary economic assessment( PEA) outlining a clear pathway to production. Permitting efforts are progressing with the Bureau of Land Management, and Lahontan anticipates being in a position to break ground by 2026.
Additionally, strategic drilling campaigns are planned to further expand the existing resource base.
The company's strategy to unlock shareholder value is to advance the Santa Fe mine toward production by derisking the project through permitting and feasibility studies, while optimizing heap leach processing for maximum recoveries and economic efficiency. Concurrently, it is unlocking value from satellite deposits, including West Santa Fe, which has high-grade oxide potential, and Moho, an early-stage project with promising historic gold and silver intercepts.
Positioned as a low-cost developer in a top-tier jurisdiction, the company maintains strong institutional support with minimal dilution risk, ensuring capital efficiency and sustainable growth.
Company Highlights
- Flagship Santa Fe Project: 100 percent owned, past-producing open-pit heap leach mine with a current MRE of 1.95 Moz gold equivalent at a grade of ~0.9 g/t.
- Strategic Nevada Location: Situated in Walker Lane, one of the world’s best mining jurisdictions, with excellent infrastructure, water access, and a mining-friendly regulatory environment.
- Strong Resource Growth Potential: The Santa Fe Mine and its satellite projects, West Santa Fe and Moho, offer exploration upside, with further drilling planned to expand resources.
- Advancing Toward Production: With a positive Preliminary Economic Assessment (PEA) completed in late 2024, Lahontan is aggressively moving toward permitting and development.
- Experienced Leadership: The company is led by an experienced management team with a proven track record in mine development, permitting, and value creation for investors.
Key Projects
Santa Fe Mine
The Santa Fe mine, located in Mineral County, Nevada, spans 26.4 sq km and represents Lahontan Gold’s flagship development project. With an updated mineral resource estimate of 1.95 Moz gold equivalent, the project hosts multiple oxide and sulfide zones that remain open for expansion.
Historical production from the Santa Fe mine yielded 356,000 oz gold and 784,000 oz silver from an open-pit heap leach operation. Modern exploration and metallurgical testing have identified additional high-grade mineralization that could support an expanded operation.
The recently completed PEA indicates strong economic potential, with favorable heap leach recoveries and low operating costs. Lahontan is actively working with the Bureau of Land Management to advance the permitting process, with the goal of achieving production readiness by 2026.
West Santa Fe
The West Santa Fe project, situated just 13 km from the Santa Fe mine, is a highly prospective satellite project that could serve as an extension of the main operation. Historic drill data suggest the presence of a shallow oxide deposit, with early resource modeling indicating a potential gold equivalent resource of 0.5 to 1 Moz.
West Santa Fe’s excellent resource growth potential
Lahontan is preparing for an extensive drill program in 2025 to validate and expand this resource. Geophysical surveys and geochemical sampling have identified strong structural controls on mineralization, further supporting the potential for economic extraction. Given its proximity to Santa Fe, West Santa Fe offers a compelling low-cost, high-margin opportunity for future production.
Moho Project
The Moho project is another 100 percent owned asset within the Walker Lane district in Nevada, presenting a longer-term growth opportunity for Lahontan. The project is characterized by historic high-grade gold and silver intercepts from past drilling, with reported grades exceeding 20 g/t gold and 300 g/t silver. Initial exploration has confirmed the presence of oxidized tertiary epithermal vein systems, which are ideal for conventional heap leach processing. Core drilling in 2019 further validated the high-grade nature of Moho’s mineralization, with significant intercepts occurring at relatively shallow depths. Lahontan plans to conduct additional exploration drilling to refine resource estimates and assess potential economic viability.

Key Projects
Kpali Gold Project
The Kpali gold project, a cornerstone of Castle Minerals' exploration efforts, is strategically located approximately 30 kilometers west of the regional town of Sawla in Ghana's Upper West region. Encompassing the Kpali and Bundi prospects, along with several satellite discoveries, the project area lies within the 170 sq km Degbiwu prospecting license (PL 10/26), which is encircled by the 1,033 sq km Gbiniyiri retention license (RL 8/27). Notably, the western boundaries of these licenses are delineated by the Black Volta River, marking the border with Burkina Faso.
Geologically, Kpali is situated at the convergence of two significant greenstone belts — the Bole-Bolgatanga and Wa-Lawra/Boromo belts — and three regional-scale structures. This unique positioning is associated with several major Birimian-hosted gold deposits in the region, enhancing the project's potential for substantial gold mineralization.
Recent exploration activities have yielded promising results. In February 2025, an eight-hole reverse circulation (RC) drilling program intersected shallow, high-grade mineralization in all holes. Notable intercepts include 12 meters at 8.29 grams per ton (g/t) gold from 25 meters, including 6 meters at 11.60 g/t gold from 31 meters, with a peak 1-meter intercept of 20.43 g/t gold at 36 meters. These findings have significantly upgraded the status of the Kpali gold prospect, suggesting the presence of multiple sub-parallel lodes with high-grade gold mineralization.
The broader district encompassing Kpali contains several other high-conviction prospects, reinforcing its potential as an emerging new exploration frontier. Castle Minerals plans to undertake further drilling programs, including step-out drilling, to delineate the extent of mineralization and assess the project's viability for future development.
In summary, the Kpali Gold Project's strategic location, favorable geology, and recent high-grade drilling results position it as a significant asset within Castle Minerals' portfolio, with the potential to evolve into a major gold production site in Ghana.
Kandia Gold Project
The Kandia gold project is situated in Ghana's Upper West Region. Discovered in 2010 during reconnaissance field mapping, the project encompasses a 16-kilometer-long corridor along a significant granite-sediment contact within Birimian greenstone terrain. This geological setting is known for hosting substantial gold mineralization, with the Kandia prospect itself identified through previously unknown artisanal workings spread over approximately 600 meters of strike.
Initial exploration efforts included extensive soil sampling, airborne geophysical surveys and RC drilling, totaling 264 holes over 19,541 meters. These activities led to the identification of two primary mineralized zones: the "4,000 Zone" and the "8,000 Zone."
Strategically, the Kandia project benefits from its proximity to major gold deposits. The 5.1-million-ounce Namdini gold project lies to the northeast on the same Bole-Bolgatanga greenstone belt, while the 2.8-million-ounce Black Volta gold project's Julie deposit is immediately along strike from the Kandia mineralized trend. This favorable location enhances Kandia's economic attractiveness and potential for development synergies.
Future exploration plans for Kandia involve extensional drilling at the "4,000 Zone" and targeted drilling in other areas with historically wide-spaced shallow drilling, such as the "8,000 Zone," where artisanal mining activities are also present. The primary objective is to delineate multiple near-surface, open-pitable deposits along the 16-kilometer prospective contact, advancing the project toward potential development.
