Pioneer Minerals Launches $1.8M Raise to Fund Option on Argentine Gold-Copper Project
Key Takeaways
- Historical drilling at San Francisco includes 109m at 4.94 g/t Au and 1.13% Cu from 12m, across 47 diamond holes and about 13,332m.
- Depth results are the standout, with 72m at 3.47% Cu from 398m and 6m at 10.93% Cu inside a 17m intercept, suggesting the system continues well below the early gold discoveries.
- Only nine breccias and one vein system have been drilled out of more than 70 breccias and 130 veins mapped, leaving most of the district untested.
- The option structure costs up to US$3.2 million in cash plus US$2.45 million in exploration spend over four years, with Pioneer free to withdraw before completing a stage.
- A$1.8 million is being raised at $0.18 per share, but the raising and the acquisition depend on shareholder approval by 31 December 2026, and no Mineral Resource has been declared.
Pioneer secures option to acquire high-grade San Francisco gold-copper-silver project
Pioneer Minerals (ASX: PMM) has entered into staged option agreements to acquire the San Francisco Gold-Copper-Silver Project in the Calingasta Department of San Juan Province, Argentina. The drilling behind the deal is historical, with headline intercepts of 109m @ 4.94 g/t Au and 1.13% Cu (SFDH-012), 72m @ 3.47% Cu (SFDH-039) and 27m @ 5.50 g/t Au and 3.30% Cu (SFDH-003).
The San Francisco breccia pipe has been tested by 47 historical diamond holes for approximately 13,332m, giving Pioneer a substantial dataset for 3D modelling. The most recent operator was Turmalina Metals Corp., which drilled between 2019 and 2021.
Pioneer has also received firm commitments to raise A$1.8 million (before costs) at $0.18 per share, with all of it subject to shareholder approval.

Historical drilling shows broad, high-grade mineralisation from surface to depth
The historical drilling indicates mineralisation is not restricted to isolated narrow veins. It occurs across substantial intervals within the breccia system, with high-grade sulphide zones sitting inside a broader mineralised envelope.
Near-surface highlights
The table below shows selected near-surface intercepts reported in the announcement. All figures are downhole lengths, and true widths are currently unknown.
| Hole | From (m) | Interval | Au (g/t) | Ag (g/t) | Cu (%) |
|---|---|---|---|---|---|
| SFDH-012 | 12 | 109m | 4.94 | 109 | 1.13 |
| SFDH-011 | 25 | 83m | 4.40 | 82 | 0.43 |
| SFDH-001 | 35 | 37m | 6.30 | 122 | 0.88 |
| SFDH-005 | 33 | 85m | 2.70 | 87 | 0.56 |
| SFDH-030 | Surface | 22m | 7.95 | 60 | 0.14 |
| SFDH-003 | 44 | 27m | 5.50 | 97 | 3.30 |
| SFDH-018 | 67 | 29m | 4.21 | 223 | 1.42 |
Several holes also contain higher-grade zones inside these intervals. SFDH-012 includes 27m @ 9.02 g/t Au from 31m, and SFDH-030 includes 6m @ 23.75 g/t Au from 3m.
Depth extensions
Drilling later stepped hundreds of metres beneath the initial near-surface discoveries. Copper at depth is the standout:
- SFDH-039: 72m @ 3.47% Cu, 100 g/t Ag and 0.71 g/t Au from 398m
- SFDH-047: 17m @ 4.33% Cu from 370m, including 6m @ 10.93% Cu
- SFDH-043: 35m @ 1.99% Cu from 109m
Silver is material too. SFDH-018 carries 223 g/t and SFDH-005 includes an interval at 173 g/t.
For you, the point is that strong copper at depth suggests the system continues beneath the early discoveries. Pioneer intends to test the continuation of mineralisation at depth and investigate the potential for a deeper feeder system.
Michael Beven, Chief Executive Officer
“Extensive historical drilling has intersected broad zones of high-grade gold, silver and copper mineralisation, including mineralisation extending to significant depths…”
What is a breccia pipe, and why does district-scale potential matter?
A breccia is rock made of broken angular fragments cemented together by finer material. At San Francisco, the mineralised body is a quartz-tourmaline hydrothermal breccia, hosted in sedimentary rocks of the Agua Negra Formation and associated intrusive rocks. Metals sit mainly in the matrix between the fragments, as sulphide minerals including pyrite, chalcopyrite and arsenopyrite.
The investment angle is scale. Historical exploration mapped more than 70 breccias and over 130 veins, yet only nine breccias and one vein system have been drill tested, with just 4,964m of drilling completed outside San Francisco.
Surface sampling adds support. Across El Tapau, historical work collected 4,795 soil samples and 2,912 surface samples, and 95 surface samples returned more than 1 g/t Au.
Treat those numbers with care. Rock-chip and float samples are selective, may be biased towards visibly mineralised material and are not necessarily representative of the grade or extent of mineralisation across the Project.
Deal terms: what does the staged option structure involve?
Pioneer was nominated by 62 Capital to acquire the purchaser’s rights under the Option Agreements, subject to shareholder approval under Listing Rule 10.1. No consideration is payable by Pioneer to 62 Capital for the nomination.
The agreements provide the right to acquire a 100% interest in the San Francisco and José Mario mining concessions and an 81.25% interest in the adjoining El Tapau permits, each subject to a 2% NSR. Together they would form a landholding of approximately 3,477 hectares.
Each agreement has a four-year term. Pioneer can withdraw before completing the relevant staged program without obligation to make future payments or incur future exploration expenditure not already due.
| Stage | Timing | Cash payment | Min. exploration spend | Drilling |
|---|---|---|---|---|
| Stage 1 | Commencement to month 12 | US$270,000 | US$250,000 | None stated |
| Stage 2 | Months 12 to 24 | US$330,000 | US$250,000 | 3km |
| Stage 3 | Months 24 to 36 | US$750,000 | US$500,000 | 4km |
| Stage 4 | Months 36 to 48 | US$1,850,000 | US$1,450,000 | None stated |
| Total | US$3,200,000 | US$2,450,000 | 7km |
The amounts are aggregated across both Option Agreements, which are separate, so Pioneer may proceed with or withdraw from either independently.
In consideration for introducing the transaction, Pioneer has agreed to issue Mr David Pevcic up to 11,000,000 shares and 11,000,000 options exercisable at $0.20. They would be issued in four equal tranches tied to each stage, subject to shareholder approval under ASX Listing Rule 7.1.
How is the A$1.8 million raising structured, and what approvals are needed?
The Placement comprises 10,000,000 shares at $0.18, equal to the last closing price on 5 October 2026. Subscribers receive one free-attaching option for every two shares, being 5,000,000 Placement Options exercisable at $0.25, expiring three years from issue and not intended to be quoted on ASX.
It runs in two tranches:
- Tranche 1: A$1.0 million of unsecured, interest-free Convertible Loans, which would convert into 5,555,556 shares, subject to shareholder approval
- Tranche 2: A$0.8 million, with 4,444,444 shares to be issued, subject to shareholder approval
Director participation of A$300,000 forms part of the raising and is also subject to shareholder approval. If approval is not obtained by 31 December 2026, the Convertible Loans will be repayable in cash and Tranche 2 will not proceed.
62 Capital, as Lead Manager, will receive a 6% capital raising fee settled by 600,000 shares and 300,000 options, plus 3,000,000 Broker Options at $0.25. These are also subject to shareholder approval.
Because 62 Capital is a substantial (10%+) holder of Pioneer, the nomination is conditional on shareholder approval under Listing Rule 10.1. The Notice of Meeting will be accompanied by an Independent Expert’s Report on whether the acquisition is fair and reasonable to shareholders whose votes are not to be disregarded.

What is Pioneer’s exploration strategy and timeline?
Following completion of the acquisition, Pioneer intends to run three concurrent workstreams:
- Independent 3D geological modelling of the San Francisco mineralised system by an experienced resource geologist
- Project-wide geological and geochemical interpretation and target generation
- A review of available geophysical data to determine the most appropriate techniques for further exploration
New drilling is then intended to verify key areas of historical mineralisation, extend beyond previous limits at depth and support a potential Mineral Resource estimation. No Mineral Resource has been declared in the announcement.
The indicative timetable, which is subject to change:
- 14 October 2026: receipt of Tranche 1 Convertible Loan funds
- Late October 2026: despatch of Notice of Meeting and Independent Expert’s Report
- Late November 2026: Annual General Meeting
- Early December 2026: conversion of Convertible Loans and settlement of Tranche 2
Funds will primarily go towards modelling, the geological, geochemical and geophysical review, acquisition costs, Year 1 option payments and expenditure, exploration across the existing portfolio, and general working capital.
Michael Beven, Chief Executive Officer
“Our exploration strategy will therefore pursue two objectives in parallel: advancing the known San Francisco mineralised system towards resource definition while systematically exploring the broader Project for additional discoveries.”
The Exploration Results are based on information compiled and reviewed by Mr Leandro Sastre Salim, a Member of the Australian Institute of Geoscientists (AIG).
