Legacy Minerals Aurelia Metals Earn-In Partner at Cobar Project Secures Major Strategic Deal
Legacy Minerals Holdings (ASX: LGM) has executed a binding Earn-in and Farm-in Agreement with Peak Gold Mines Pty Ltd, a wholly-owned subsidiary of ASX-listed Aurelia Metals Limited (ASX: AMI), over its 100% owned Cobar Project in New South Wales. The Legacy Minerals Aurelia Metals earn-in partner at Cobar Project deal brings one of the Cobar Basin's most established producers directly into the project, with Aurelia committing to sole-fund up to $2.0 million in exploration over five years at no cost to Legacy Minerals shareholders, whilst Legacy retains meaningful upside through either a joint venture interest or a perpetual royalty position.
The agreement is strategically significant on two levels: it activates the Cobar Project's exploration potential through a well-resourced, regionally embedded partner, and it allows Legacy Minerals to sharpen its own capital and management focus squarely on its flagship Mt Carrington gold-silver project.
"Securing Aurelia Metals as our earn-in partner at the Cobar Project is a strategically significant outcome for Legacy Minerals shareholders. Aurelia is one of the most established operators in the Cobar Basin, and its option to sole-fund up to $2.0 million of exploration over five years provides a meaningful discovery opportunity for our shareholders… This Agreement reflects our strategy of advancing projects with high-calibre partners whilst directing Legacy's own capital and technical capability towards our flagship Mt Carrington gold-silver project."
— Christopher Byrne, CEO & Managing Director, Legacy Minerals

| Legacy Election at Stage 2 | Either (i) participate in a 10% JV interest or (ii) convert to a 1.5% NSR royalty on gold and 1.0% NSR royalty on base metals, in perpetuity |
A critical protective clause for Legacy shareholders is the data reversion provision: should Aurelia withdraw at any point prior to earning its Stage 2 interest, all exploration data and mining information generated under the Agreement reverts entirely to Legacy Minerals. This arrangement ensures the Company builds long-term geological knowledge of the tenements regardless of outcome.
Why the Cobar Basin Matters
The Cobar Basin represents one of Australia's most historically productive polymetallic mineral provinces, hosting multiple long-life operating mines producing copper, gold, lead, zinc, and silver. The region benefits from an established mining workforce, processing infrastructure, and a well-developed supply chain — conditions that materially reduce the lead time and cost from exploration discovery to development decision.
The Cobar Project tenements are situated immediately along strike from operating mines in the district and are interpreted to host the structural and geological settings considered favourable for Cobar-style polymetallic mineralisation. The project area contains a portfolio of targets developed from soil geochemistry, airborne geophysics, and structural interpretation — a foundation ready for systematic drilling.
What makes this agreement particularly compelling is the identity of the drilling partner. Aurelia Metals operates the nearby Peak Mine and holds processing infrastructure in the basin. That proximity transforms any future discovery from a stranded resource into one with a credible, near-term development path — a factor that can materially affect the value attributed to any ore body found.
Understanding the Earn-In Structure: A Primer for Investors
What Is an Earn-In/Farm-In Agreement?
An earn-in (or farm-in) agreement is a common structure in the minerals exploration industry that allows one party (the "farmee" — in this case, Aurelia Metals) to acquire an interest in another party's project (the "farmor" — Legacy Minerals) by spending an agreed amount on exploration. The key benefit to the asset holder is that exploration work is funded entirely by the incoming partner, with no dilution of the existing shareholder base through share issuances.
Why It Matters for Legacy Minerals Investors
- Zero cost to Legacy: Aurelia funds all exploration. Legacy Minerals does not contribute capital during the earn-in period.
- Retained upside: Legacy keeps either a 10% JV interest or a perpetual royalty — both represent ongoing economic exposure to any discovery.
- Discovery leverage: If a significant ore body is found, Legacy shareholders benefit through their retained interest, without having funded the work that led to discovery.
- Data protection: Exploration results revert to Legacy if Aurelia exits, preserving long-term value.
Glossary of Key Terms
| Term | Definition |
|---|---|
| Earn-In / Farm-In | Agreement where a party acquires a project interest by funding agreed exploration expenditure |
| NSR Royalty (Net Smelter Return) | A royalty calculated as a percentage of revenue from metal sales, paid to the royalty holder regardless of operating costs |
| JV (Joint Venture) | A partnership where parties share project costs and economic returns in proportion to their interests |
| Polymetallic | Referring to mineralisation containing multiple economically valuable metals (e.g., Cu, Au, Pb, Zn, Ag) |
| Cobar-style mineralisation | A category of high-grade, structurally controlled base and precious metal deposits characteristic of the Cobar Basin |
| Sole Operator | The party with full responsibility for managing and funding exploration programs during the earn-in period |
What This Means for Legacy's Broader Portfolio Strategy
This agreement is not an isolated transaction — it represents a deliberate expression of Legacy Minerals' portfolio management philosophy. The Company operates a broad NSW exploration portfolio, and this deal illustrates how Legacy intends to extract value from non-flagship assets without diverting its own capital away from Mt Carrington.
Legacy Minerals' NSW Portfolio Overview
| Project | Commodity Focus | Status |
|---|---|---|
| Mt Carrington (flagship) | Au-Ag, Cu-Zn-Pb | Active — ongoing drilling and resource growth |
| Cobar | Au-Cu-Pb-Zn | Aurelia Metals earn-in agreement (this announcement) |
| Harden Hill Tops | Au | Earn-in agreement in place |
| Thomson | Au-Cu (intrusion-related) | Rio Tinto option agreement |
| Fontenoy | PGE, Ni, Au, Cu | Earth AI joint venture |
| Rockley | Cu-Au (porphyry) | Exploration stage |
| Bauloora | Au-Ag (epithermal) | Exploration stage |
| Black Range | Au-Ag (epithermal) | Exploration stage |
| Nico Young Cobalt Blue | Ni-Co | MoU in place |
The pattern is clear: Legacy Minerals is systematically converting non-core assets into funded exploration programs through credible partners — Rio Tinto at Thomson, Earth AI at Fontenoy, and now Aurelia Metals at Cobar — whilst concentrating its own resources at Mt Carrington.
Mt Carrington: The Flagship Remains the Priority
Whilst the Cobar agreement is strategically significant, Legacy Minerals is explicit that Mt Carrington remains its primary focus. The project hosts an existing Mineral Resource of 1.2 Moz AuEq (equivalent to 115 Moz AgEq), including 24 Moz Ag, 0.7 Moz Au, and 200kt Zn-Pb-Cu, within a large caldera system of approximately 150 km² in New South Wales.
Furthermore, recent drilling at Mt Carrington has returned results that underscore the project's discovery potential:
- 118m at 1.71 g/t Au, 6.9 g/t Ag, 0.1% Cu and 1.12% Zn from 2m (KYDD003)
- 18.9m at 5.8% Cu from 58m and 10.1m at 7.26% Cu from 88m (KYDD001)
- 143m at 1.1 g/t Au, 3 g/t Ag and 0.9% Pb+Zn from 0m (RRDD009)
- 8m at 16.92 g/t Au, 17 g/t Ag, 0.53% Cu, 1.45% Pb and 6.89% Zn from 52m (RED003)
- 37.1m at 422 g/t Ag, 0.2 g/t Au, 1.5% Pb+Zn from 0m (PWR128)
The combination of shallow, high-grade intercepts and a large, underexplored epithermal system provides a substantial runway for resource growth. Consequently, by securing the Aurelia earn-in, Legacy has ensured that this focus is not financially diluted by the demands of running a parallel exploration programme at Cobar.
Upcoming Catalysts and Key Milestones to Watch
Near-Term (0–24 Months)
- Aurelia commences Stage 1 exploration — Aurelia takes over as operator and begins deploying the first $500,000 of exploration at the Cobar Project within two years of commencement.
- Mt Carrington drilling continuation — Legacy directs its own capital and technical team toward discovery and resource growth at Mt Carrington.
- First exploration results from Cobar — Initial soil geochemistry, geophysics, and/or drilling results under Aurelia's programme provide the first systematic look at the tenements.
Medium-Term (2–5 Years)
- Stage 1 completion — Aurelia earns its 51% interest upon spending $500,000; Stage 2 programme commences.
- Stage 2 completion — Aurelia earns 90% total interest upon spending a further $1.5 million; Legacy elects between JV participation or royalty conversion.
- Mt Carrington resource updates — Continued drilling expected to grow and refine the existing 1.2 Moz AuEq resource base.
The Investment Case: Why This Announcement Matters
1. Funded Exploration at No Cost to Shareholders
The entire Cobar exploration budget — up to $2.0 million — is funded by Aurelia Metals. Legacy Minerals shareholders therefore gain exposure to exploration upside in one of Australia's premier polymetallic basins without any capital contribution or share dilution.
2. A Partner with Infrastructure Already in Place
Aurelia Metals operates the nearby Peak Mine and holds processing infrastructure in the Cobar Basin. This dramatically reduces the development risk and timeline for any future discovery, making the exploration programme more than a purely speculative exercise.
3. Retained Upside Through Royalty or JV
Legacy's election right — to either hold a 10% JV interest or convert to a perpetual NSR royalty — means shareholders retain meaningful exposure to any discovery regardless of which path is chosen. In addition, a perpetual NSR royalty requires no future capital contribution whilst providing ongoing revenue participation.
4. Capital Efficiency Across the Portfolio
By monetising the exploration potential of non-flagship assets through earn-in partnerships, Legacy Minerals achieves more with its available capital. The Company can advance Mt Carrington aggressively whilst simultaneously progressing Cobar, Harden, Thomson, and Fontenoy through partner-funded programmes.
5. Data Protection Clause Adds a Floor to Value
The reversion of all exploration data to Legacy Minerals upon any Aurelia withdrawal ensures the Company retains the geological intelligence generated, regardless of whether the partnership runs its full course.
