TSO - TESORO GOLD LTD
Investment Thesis
Tesoro Gold is a Chilean gold developer sitting on one of the highest-grade intercept packages in South America — yet it trades at a A$195M market cap implying just A$92/oz EV per resource ounce. The Ternera deposit has now delivered multiple drill holes that would be headline news at any major: ZDDH0394 (46.67m @ 11.86 g/t Au, including 0.5m @ 924 g/t visible gold) and ZDDH0297 (434.60m @ 1.22 g/t — one of the widest gold intercepts on the continent) together define a deposit with both the grade to generate exceptional FCF per tonne and the bulk tonnage to sustain a 110koz/year operation. Hartleys' mine modelling pegs production at 110koz per annum — at today's A$5,000/oz gold spot, that's roughly A$330-365M in annual free cash flow at estimated AISC of A$1,650-1,700/oz. TSO's current enterprise value of A$167M is less than half of one year's projected FCF. The market is pricing TSO as an explorer with a Chilean permitting discount. That discount is warranted partially — Chile is complex and capital-intensive — but the size of the gap between current valuation and any reasonable mine-plan-based DCF is far too wide. Three de-risking steps (resource upgrade, PFS, environmental permits) each close the discount independently. With gold at all-time highs in AUD terms and M&A activity heating up in South America, TSO is significantly undervalued.
What No One Else Is Seeing
Ternera Hosts One of the Best Drill Holes in Chile
ZDDH0394 (46.67m @ 11.86 g/t Au, including 0.5m @ 924 g/t) is not a typical porphyry bulk-tonnage result — this is bonanza-grade epithermal gold. Combined with ZDDH0288 (63.93m @ 7.61 g/t) and ZDDH0338 (1.80m @ 77.15 g/t), there is a high-grade shoot within the wider system that could dramatically reduce AISC through selective mining of early-year high-grade ore. Most Chilean gold developers do not have this quality of high-grade core.
Monster Width Confirms Bulk-Tonnage Optionality
ZDDH0297 (434.60m @ 1.22 g/t Au) is one of the widest single gold intercepts in Chile's Atacama region. At 434m of continuous mineralisation, this defines a genuinely large open-pittable target. The combination of wide low-grade (bulk tonnage) plus discrete high-grade shoots (ZDDH0394, ZDDH0288) gives TSO's mine plan flexibility — the project can be sequenced to high-grade early years to recover capex quickly.
110koz/Year Target Is Credible — Sub-A$200M Mcap Doesn't Reflect It
A 110koz/year Chilean gold producer at today's A$5,000/oz spot would generate roughly A$330-360M in annual free cash flow at estimated AISC of A$1,650-1,700/oz. At just 1.5x that annual FCF, the implied market cap would be A$495-540M — more than 2.5x TSO's current A$195M. The market is still pricing TSO as an explorer rather than a developer with a validated mine plan.
Chilean Permitting and Tax Regime Remains the Key Overhang
Chile's mining royalty regime (amended to up to 46.5% effective tax on large projects) and water rights in the Atacama add meaningful development risk. Permitting timelines have blown out industry-wide: projects that expected 18-24 months have taken 4-5 years. TSO needs to demonstrate a clear permitting pathway before the market will fully re-rate to producer multiples.
Trading at A$91/oz EV — Less Than Half of Peer Re-Rating Target
At A$195M mcap less estimated A$28M net cash, TSO's EV is ~A$167M against a 1.82Moz resource = A$92/oz. Chilean gold developers with mine plans trade at A$150-200/oz once a DFS is released. On a re-rating to A$160/oz (conservative DFS multiple), plus resource growth to 2.2Moz, implied mcap reaches A$380M+ (A$2.08/share). At full producer re-rating of A$200/oz and 2.5Moz, the target is A$530M+ (A$2.91/share).
Three De-Risking Events Could Drive Sequential Re-Ratings
TSO's re-rating likely happens in stages: (1) resource upgrade to 2.2-2.5Moz on back of current drilling = first leg; (2) scoping study/PFS confirming 110koz/year at sub-A$1,700/oz AISC = second leg; (3) environmental permits secured = final leg before construction decision. Each stage removes a discount, and at current A$1.07 all three de-risking events are substantially unpriced.

Valuation & Price Target
NAV methodology: 110koz/year production over 13-year mine life (1.43Moz mineable at 78% recovery from 1.82Moz resource). Base case assumes A$4,800/oz gold, A$1,700/oz AISC, A$450M development capex, 3-year construction start. Unlevered NPV8% = ~A$2.2B. Risk-adjusted at 35% discount for development-stage uncertainty and Chilean jurisdiction = ~A$1.43B (A$7.84/share). More conservative EV/oz peer multiple approach: at A$160/oz on 2.2Moz projected resource = A$352M EV + A$28M cash = A$380M market cap = A$2.08/share (base). Price target set at A$3.60 (base) as a blend of DCF and conservative peer multiples with full credit for mine plan confirmation but partial discount for permitting risk and capex execution.
Key Risks
Chilean permitting complexity is the dominant risk — the DGA (water regulator) and SEIA (environmental regulator) can take 3-5 years for large gold projects in the Atacama. Royalty regime uncertainty: Chile's 46.5% effective tax on large projects compresses free cash flow materially. Single asset concentration: 100% of TSO's value sits in El Zorro; metallurgical surprises or resource downgrade would have outsized impact. Dilution: the mine plan requires ~A$450M capex that TSO cannot self-fund at current size; significant dilution or debt is inevitable. Water access: the Atacama region has chronic water scarcity; desalination adds A$50-80M to capex. Execution risk: management has never built a mine of this scale.
Key Catalysts
| Date | Event |
|---|---|
| H2 2026 | Resource update incorporating current Ternera drilling — potential upgrade to 2.2-2.5Moz Au, first leg re-rating trigger |
| H1 2027 | Scoping Study or PFS release confirming 110koz/year production profile — the pivotal de-risking event |
| 2027 | Environmental Impact Assessment lodged with Chilean DGA — clears path to development approval |
| H2 2027 | DFS completion — unlocks project financing and M&A appeal |
The numbers are hard to ignore. You have a company with a mine plan targeting 110koz/year of gold, with some of the best drill results in Chilean history sitting in the ground at Ternera — 46.67m @ 11.86 g/t, 434m of continuous mineralisation, 924 g/t visible gold nuggets — and it trades at A$195M. A comparable producer making 110koz/year would trade at A$800M-1.5B. Even with a 70% development discount, that implies A$240-450M. The current price doesn't just look cheap; it looks like the market hasn't fully processed what the Ternera drilling program has found. Chilean risk is real and shouldn't be waved away — permitting is genuinely hard and the tax regime is genuinely punitive. But those risks are well-known and arguably already in the price. What's NOT in the price is the quality of the geology. The bull case here isn't predicated on gold going higher (though that helps); it's predicated on the market recognising that what Tesoro has in the ground is genuinely exceptional.
