Metal Hawk Limited (ASX: MHK, “Metal Hawk” or the “Company”) is pleased to provide an exploration update for its 100% owned Leinster South project, located 30km south of Leinster in the Western Australian goldfields. Since the Company returned high-grade gold results from rockchip sampling at the Siberian Tiger prospect (see ASX announcement 5 August 2024), further exploration activities have commenced and Metal Hawk is progressing towards a maiden drilling program at the prospect as soon as possible.
- High resolution UAV (drone) magnetic survey underway at Leinster South, covering the majority of western tenement E 36/1068 which includes the Siberian Tiger gold prospect.
- New detailed geophysical data will significantly enhance the geological and structural understanding of the project area and will further assist Metal Hawk with identifying targets for drilling.
- Reconnaissance rockchip samples at Siberian Tiger returned high grade gold up to 20.2g/t from outcropping quartz veining. Additional samples of outcropping quartz veins along strike from Siberian Tiger have been delivered to the laboratory for gold and multi-element analysis.
- New tenement applications expand the Leinster South project area to over 430km2.
- Heritage negotiations and drilling approvals are underway.
The Company recently applied for two new exploration licenses to the east of Siberian Tiger, increasing the Leinster South project area to more than 430km2. This is a significant landholding in one of the most well-endowed gold regions of WA. The Siberian Tiger gold discovery is located along the southern limb of the Lawlers anticline and only 15km from the Lawlers mining centre (Figure 1). Past production from the Agnew - Lawlers deposits is > 5 million oz @ 5gt Au1.

A high-resolution UAV (drone) magnetic survey has commenced, with 50m spaced east-west lines at a flying height of 25m conducted over the majority of Leinster South tenement E36/1068, which includes the Siberian Tiger gold prospect. The Pegasus Airborne UAV system is able to quickly and efficiently provide high quality, detailed magnetic data which can be used to identify important structures and geological features of gold deposits. The magnetic survey will assist Metal Hawk geologists with targeting at Siberian Tiger and other regional prospect areas. Processing and interpretation of geophysical data will be carried out immediately following completion of the survey, which is expected to take 3-4 days.
Metal Hawk’s Managing Director Will Belbin commented: “We are collecting important geochemical, structural and geophysical data to better understand the controls and potential characteristics of gold mineralisation in the area. The drone magnetic survey will enable better interpretation of the subsurface geology and ultimately help us to determine the best possible target locations for the maiden drilling program at Siberian Tiger.”
“Whilst the historical geophysical dataset over the Leinster South tenure is poor, we expect that the new magnetic survey will show excellent detail and key structural features of the pronounced southeast trending greenstone belt.”

Key Projects
El Potrero Gold-Silver Project
El Potrero is a high-grade, past-producing gold-silver project located in the prolific Sierra Madre Belt in Mexico, within 35 km of four operating mines, including Fresnillo’s 4,000 tpd Ciénega Mine. The project comprises two concession blocks totaling 1,074 hectares, which include the historic mines and a 100 tpd on-site processing plant.
Recent Developments (as of July 2025):
- Over 600 rock samples have been collected from underground and surface sources for geochemical analysis.
- Channel sampling at the Pinos Cuates mine returned assays of up to 85.1 g/t gold and 520 g/t silver over 0.5 m, and composite intervals of 50.3 g/t gold and 269 g/t silver over 1.7 m.
- Geological interpretation highlights a significant quartz-feldspar porphyry dyke as a structural control on gold-silver mineralization.
- The Dos de Mayo vein system has been mapped over 1.6 km with trench and underground samples showing high-grade mineralization, including 13.2 g/t gold and 2,280 g/t silver from surface grab samples.
- Work is underway to design an underground and surface drill program to define continuity and guide future mine development.
- A site inspection of the 100 tpd plant confirmed that the base infrastructure is sound. Refurbishment of key equipment (crusher, mill, Merrill Crowe circuit) is being planned.
- Permitting efforts are progressing efficiently, aided by the site's historical disturbance. Baseline studies and formal permitting proposals are underway.
Pinnacle can earn an initial 50 percent interest upon production and increase its ownership of El Potrero to 100 percent subject to a 2 percent NSR, primarily through cash flow-funded payments, offering a low-dilution path to full ownership.

Sun Summit Provides Exploration Update from the JD Project in BC's Toodoggone District; Over 3,100 Meters of Drilling Completed at the Creek Zone
- Drilling nearly complete at the Creek zone: Over 3,100 meters of drilling have been completed across ten holes at the Creek zone, with additional drill holes planned. The holes investigated the extent and continuity of near-surface, high-grade and bulk-tonnage gold mineralization. Historical and recent highlight intercepts from 2024 drilling at the Creek zone include:
- 122.53 m of 2.11 g/t Au including 1.5 of 121.0 g/t Au (CZ-24-0047)
- 54.95 m of 2.69 g/t Au including 19.50 m of 7.31 g/t Au (CZ-24-0058)
- 22.0 m of 11.7 g/t Au including 4.0 m of 61.2 g/t Au (CZ97-0085)
- Drilling to follow at the Finn zone where up to 2,000 meters are planned: Holes are designed to evaluate the extent and continuity of high-grade and bulk-tonnage gold-silver mineralization. Historical highlight intercepts (Figure 4) include:
- 35.7 m of 7.26 g/t Au, 94 g/t Ag including 1.0 m of 215.4 g/t Au, 308 g/t Ag (JD95-0472)
- 45.0 m of 3.02 g/t Au, 143 g/t Ag including 5.0 m of 8.18 g/t Au, 918 g/t Ag (JD95-0762)
- 20.85 m of 8.76 g/t Au, 68 g/t Ag including 11.0 m of 15.1 g/t Au,108 g/t Ag (JD95-0972)
- 22.0 m of 6.32 g/t Au, 46 g/t Ag including 12.6 m of 10.8 g/t Au, 66 g/t Ag (JD12-0033)
- Project-wide exploration activities focused on drill target refinement are ongoing, including:
- Over 20 line-km of induced polarization (IP) geophysics has been completed along the JD Porphyry Trend. Infill surveying across the Finn to Creek corridor is set to commence in the coming weeks.
- Over 1,600 soil samples have now been collected across the Belle South grid, the southern extent of the JD Porphyry trend, and the Kadah grid near the Finn to Creek corridor.
- Geological mapping and prospecting are ongoing with a current focus on McClair Creek which transects the JD Porphyry Trend as well as the McClair East area.
"Our fully funded $6 million exploration program designed to systematically advance and expand the gold-silver targets at JD is progressing nicely," said Niel Marotta, CEO of Sun Summit Minerals. "We have made terrific progress at Creek Zone. We are excited about the upcoming drilling at the Finn Zone, where we plan to test the extent of gold mineralization while also investigating a zone of strong silver mineralization, recently modelled through our comprehensive compilation efforts. We expect to begin reporting results from drilling completed at the Creek Zone in the coming weeks, with results from additional targets to follow."
2025 JD Exploration Program
The primary exploration goals at JD in 2025 are to advance and expand the Creek and Finn gold-silver targets and to generate and refine new priority targets across the project. Work is currently focused on the highly prospective 4.5 km long epithermal-related Finn to Creek corridor, as well as the 12 km long JD Porphyry trend (Figure 1).
Drilling update:
Over 3,100 meters of drilling has been completed at the Creek zone with holes collared along a 500-meter northwest-southeast trend. Ten holes investigated the extent and continuity of near-surface, high-grade and bulk-tonnage gold mineralization (e.g., 122.53 m of 2.11 g/t Au including 1.5 of 121.0 g/t Au in CZ-24-0047 and 22.0 m of 11.7 g/t Au including 4.0 m of 61.2 g/t Au in CZ97-0085, Figure 3). Holes were designed to systematically test the vein-controlling structures on 50 to 100 meter pierce-points covering a strike-length of over 500 meters and a down-dip extent of over 200 meters.
Up to 2,000 meters of drilling is planned at the Finn zone with holes designed to investigate the down-dip, strike extent and continuity of near-surface, high-grade and bulk-tonnage gold-silver mineralization (e.g., 35.7 m of 7.26 g/t Au, 94 g/t Ag including 1.0 m of 215.4 g/t Au, 308 g/t Ag in JD95-0472 and 20.85 m of 8.76 g/t Au, 68 g/t Ag including 11.0 m of 15.1 g/t Au,108 g/t Ag in JD95-0972, Figure 4).
Modelling of recently compiled historical Finn zone drill data has outlined a compelling zone of strong silver-gold-base metal mineralization (e.g., 45.0 m of 3.02 g/t Au, 136 g/t Ag including 5.0 m of 8.18 g/t Au, 918 g/t Ag in JD95-0762). Planned drilling at Finn will also be aimed at investigating the structural and/or lithological controls on this gold-associated, silver-rich mineralization.
Target generation update: Project-wide exploration activities aimed at target generation and drill target refinement are ongoing, including:
- Over 20 line km of induced polarization (IP) geophysical surveying has been completed along the JD Porphyry trend east of the Finn Zone. Additional surveying is set to commence in the coming weeks covering parts of the Finn to Creek corridor to infill historical gaps.
- Over 1,600 soil samples have now been collected across the Belle South grid, southern extent of the porphyry trend (Figure 2) and the Kadah grid which covers a highly prospective area south of the Finn to Creek corridor lacking historical soil coverage.
- Geological mapping and prospecting are ongoing with a current focus on McClair Creek which transects the JD Porphyry trend. Mapping has also been completed along the Finn to Creek corridor as well as the Oxide Peak West target. Mapping will continue east towards the East McClair copper target.
Timeline: Drilling and complementary exploration activities are anticipated to continue into early October. Soil and rock samples and drill core samples from the first eight holes at Creek zone have now been submitted to the lab for assay analyses. Results will be released once compiled and interpreted.

About the JD Project
The JD Project is located in the Toodoggone mining district in north-central British Columbia, a highly prospective deposit-rich mineral trend. The project covers an area of over 15,000 hectares and is in close proximity to active exploration and development projects, such as Thesis Gold's Lawyers and Ranch projects, TDG Gold's Baker-Shasta projects, Amarc Resource's AuRORA project, Centerra's Gold's Kemess East and Underground projects, as well as the past-producing Kemess open pit copper-gold mine.
The project is 450 kilometres northwest of the city of Prince George, and 25 kilometres north of the Sturdee airstrip. It is proximal to existing infrastructure in place to support the past-producing Kemess mine, including roads and a hydroelectric power line.
The JD Project is in a favourable geological environment characterized by both high-grade epithermal gold and silver mineralization, as well as porphyry-related copper and gold mineralization. Some historical exploration, including drilling, geochemistry and geophysics, has been carried out on the property, however the project area is largely underexplored.
