Hammer Metals launches targeted copper-gold drilling at Lex, Mascotte, and Tourist Zone South

Hammer Metals Limited (ASX: HMX) has officially commenced a ~1,500-metre Reverse Circulation (RC) drilling campaign across three highly prospective, 100%-owned copper-gold targets in the renowned Mount Isa district of Northwest Queensland. The drilling initiative, announced on 24 April 2025, seeks to unlock new mineralisation opportunities at Lex, Tourist Zone South, and Mount Mascotte, intensifying the company’s exploration momentum in one of Australia’s most historically significant mining regions.

The targeted drill program follows promising geophysical and geochemical survey results, as Hammer Metals continues its dual strategy of advancing wholly owned prospects while progressing its fully-funded joint ventures with Sumitomo Metal Mining Oceania and South32 Limited. Drilling operations are anticipated to conclude by early May 2025, with assay results expected between late May and early June, setting up a crucial period for Hammer’s exploration narrative.

Why is the Lex Target Drawing Attention?

The Lex prospect emerged as a standout during Hammer Metals’ 2024 VTEM survey over the Mascotte and Revenue areas. A significant EM conductor with a strength of approximately 2,000 Siemens was delineated through subsequent Fixed Loop Electromagnetic (FLEM) surveys. The conductor coincides with a discrete magnetic anomaly, amplifying its prospectivity. Located beneath shallow cover with limited subcrop, the area has already yielded historical rock chip assays of up to 3.1% copper.

Hammer Metals’ exploration team noted that the Lex conductor is situated west of the Revenue trend, an area marked by historical copper and gold workings where past drilling encountered metre-scale mineralised zones. Significantly, the Lex anomaly is associated with intermediate to mafic schists — contrasting the more magnetic calc-silicate dominated Revenue trend — and is seen as highly prospective for a shear-hosted, zoned sulphide system grading from pyrrhotite to chalcopyrite mineralisation.

Two distinct EM plates have been modelled at Lex: a high-conductance plate potentially representing a steeply plunging sulphide shoot and a peripheral lower-conductance plate. The coincident magnetic and electromagnetic signatures at Lex suggest the presence of a mineralised system of economic interest, offering compelling drill targets for the current program.

What Makes the Tourist Zone South an Exciting Prospect?

Located just 8.5 kilometres west of the Kalman Deposit, the Tourist Zone South prospect is positioned along a shear zone style mineralisation trend comparable to Aeris Resources’ Barbara and Mt Colin Deposits. The proximity to the Kalman resource elevates the strategic importance of any mineralisation uncovered in this area.

Hammer Metals’ 2024 exploration activities focused on a new area approximately two kilometres south of prior drilling. Here, robust copper-gold soil anomalies have been identified over a strike length exceeding one kilometre, significantly stronger than previous geochemical results further north. Historical drilling by Hammer Metals returned standout intercepts, including 30 metres at 0.8% copper and 0.24 grams per tonne gold from 121 metres depth, and 12 metres at 1.14% copper and 0.18 grams per tonne gold from 107 metres.

Geological mapping suggests that Tourist Zone South comprises mafic rocks and sandy calc-silicate units flanking a north-south trending shear zone. Surface workings reveal zones of malachite and chalcocite mineralisation up to 10 metres wide, with rock chip sampling recording peak assays of 24.4% copper and 0.74 grams per tonne gold. Up to ten new RC holes are planned in this area, targeting the extensive soil anomaly and associated mineralised structures.

How Will Drilling at Mount Mascotte Build on Historical Success?

Mount Mascotte and Mascotte West represent another focal point for Hammer Metals’ current program. Originally mined in the early 1900s, the Mascotte area saw limited modern exploration until Hammer Metals’ 2023 drilling campaign. That initiative delivered highly encouraging results, including intersections such as 53 metres at 1.55% copper from 77 metres, with richer zones like 12 metres at 2.48% copper and 0.71 grams per tonne gold.

Additionally, standout results included 4 metres at 4.82% copper and 3.84 grams per tonne gold from 104 metres. Another significant intercept at Mascotte West comprised 6 metres at 3.73% copper and 1.47 grams per tonne gold from 50 metres. Hammer Metals’ current drilling at Mount Mascotte will aim to extend these high-grade zones along strike to the south and at depth, potentially enhancing the economic scale of the discovery.

How Do Hammer Metals’ Broader Exploration Plans Align With This Program?

Beyond the Lex, Tourist Zone South, and Mascotte drilling campaigns, Hammer Metals is executing a broader exploration roadmap across its portfolio. The Bullrush joint venture with Sumitomo Metal Mining Oceania faced a temporary suspension due to a significant rain event but has since resumed drilling. The Bullrush diamond drilling program, approximately 60% complete as of mid-April, is expected to finish by month-end, with results anticipated in May and June.

Similarly, the Isa Valley joint venture with South32 Limited is scheduled to commence drilling this quarter, reinforcing Hammer’s exposure to copper-gold exploration through strategic partnerships.

Meanwhile, Hammer Metals is concluding a strategic review of its Yandal Gold Project in Western Australia. New targets at Bronzewing South and Ken’s Bore are poised for upcoming drilling campaigns, with results expected during mid-2025. Hammer’s expansive soil sampling program across its 100%-owned tenements is also set to contribute to a steady flow of exploration updates through mid-year.

What Is the Latest Sentiment and Stock Performance for Hammer Metals?

Hammer Metals’ share price closed at A$0.025 on 24 April 2025, representing a 19.05% surge from the previous session. Despite this strong short-term performance, the stock has declined by approximately 44% over the past year, oscillating between a 52-week high of A$0.05 and a low of A$0.02. Hammer Metals currently holds a modest market capitalisation of around A$22.19 million.

Institutional ownership remains minimal, reflecting the typical profile of early-stage exploration companies. Notably, insiders own about 38.74% of the company, with Paul Clarke and Zbigniew Lubieniecki holding significant stakes of 10.4% and 7.25%, respectively.

Short-term forecasts suggest potential share price volatility, with some models predicting a possible decline to around A$0.0177. Nevertheless, speculative investors remain attentive to the company’s strong leverage to positive drilling results, given the low enterprise value and the transformative potential of even modest copper-gold discoveries.

From an investment strategy perspective, aggressive investors with a high-risk appetite might consider a speculative Buy, anticipating drill success as a catalyst for re-rating. Existing shareholders may prudently Hold pending assay results, while risk-averse investors could explore partial exits given prevailing uncertainty.

Overall, sentiment towards Hammer Metals is cautiously optimistic, hinging largely on the upcoming drilling outcomes and broader market appetite for junior copper explorers.

Why Hammer Metals’ Drilling Campaign Could Reshape Its Future

Hammer Metals’ decision to launch a multi-pronged, 100%-owned RC drilling campaign is emblematic of a junior explorer intent on securing a material discovery in a tightening global copper market. With strategically selected targets at Lex, Tourist Zone South, and Mount Mascotte, the company is aligning geological promise with operational execution.

The months ahead, marked by critical assay results and JV progress updates, will be pivotal. Successful intersections could dramatically enhance Hammer’s valuation, attract greater institutional interest, and elevate its profile as a rising force within Australia’s copper-gold exploration space.
