Axo Metals Eyes Near-Term Gold Production at San Antonio With September PEA in Focus

• Axo Metals (TSXV:AXO) acquired the San Antonio gold project in Sonora, Mexico in January and is simultaneously running infill and expansion drilling while advancing toward a Preliminary Economic Assessment (PEA) targeted for September.
• The Sapuchi starter pit offers a low strip ratio, near-surface oxide mineralisation and access to fully intact, care-and-maintained heap leach infrastructure last operated by Osisko in 2021, materially compressing the capital requirements for initial production.
• Infill drilling at Sapuchi is returning positive surprises including mineralisation in zones previously classified as waste which could lower the effective strip ratio and improve overall project economics beyond initial expectations.
• Axo Metals recently raised $40 million and management believes the incremental capital required to reach first production is in the $10's of millions of dollars given the brownfield nature of the asset.
• The company sees a pathway from the current 1.1 million ounce resource (2021 estimate at sub-$2,000/oz gold) toward 1.5-2 million ounces, with long-term production potential of 100,000-150,000 ounces per year underpinned by a future milling circuit targeting sulphide mineralisation.

Axo Metals (AXO), led by President and CEO Jonathan Egilo, is pushing its flagship San Antonio gold project in Sonora, Mexico through a pivotal development phase following its acquisition in January of this year. With an active drilling program, a PEA due in September, and a permit application filed at the start of 2026, the company is working across exploration, engineering, and regulatory workstreams in parallel. For investors evaluating the junior gold development space, San Antonio presents a relatively unusual combination: an existing brownfield infrastructure base, near-surface oxide mineralisation, a permitting group with a proven track record in Mexico, and a management team that has publicly committed to production - not merely optionality.

Brownfield Oxide Heap Leach With Operating History

San Antonio is not a greenfield discovery as the project has been operated as an open-pit heap leach gold mine from 2011 to 2018, and previous owner was producing gold as recently as 2021. When Axo Metals took ownership, it inherited infrastructure that had been kept in a state of care and maintenance by a skeleton crew, including irrigation of leach lines and maintenance of process columns. Critically, Osisko had also installed a 12,000-tonne-per-day crusher on site before its own permitting process stalled under the previous Mexican administration.

The operational history means Axo Metals is not embarking on a new build in the traditional sense. As Egilo explained: 

"It's not so much entering a new build. It's really taking an existing heap leach mine and doing the necessary work that you'd have to do for any existing mine to just go after a new deposit."

That work primarily involves constructing a haul road, expanding leach pad capacity, and completing a modest strip to access fresh ore - with the company noting that mineralisation begins directly at surface at Sapuchi deposit.

Sapuchi: The Starter Pit Driving Early Economics

Axo Metals' near-term development focus is Sapuchi, a low-strip starter pit characterised by shallow, wide mineralisation. The pit's geometry described as a mineralised hill means stripping is minimal and the operation can begin in ore almost immediately. Infill drilling is currently underway to bring the resource to reserve-level spacing in preparation for a production decision.

Beyond the box-ticking nature of a standard infill program, drilling at Sapuchi is returning results that are exceeding expectations. Several holes have intercepted significant mineralisation in areas previously modelled as waste, including intervals that could carry sufficient grade to justify heap leach processing when the material is already within the planned pit shell. One intercept returned approximately 24 metres at over two grams per tonne in an area not previously modelled at that grade over that width.

Egilo was direct about what this means for the development timeline: 

"We don't frankly need to see much more of a threshold to commit to going to production. We applied for a permit this past January and we're thinking, based on the work at Silver Tiger, maybe it'll take us 12 months. So if we could have a permit by early next year have a minimal build in front of us."

Resource Scale From 1.1 Million Ounces and Growing

The most recent resource estimate for San Antonio, published in 2021 at a gold price below $2,000 per ounce, stands at just over one million ounces. Axo Metals believes the true scale of the system is substantially larger, and has committed 5,000 metres of step-out and expansion drilling to begin demonstrating this to the market with flexibility to increase that program to 20,000-25,000 metres if early results warrant it, funded from the company's $40 million treasury.

Management's internal expectation is that re-running the existing resource at current gold prices would push the number closer to 1.5 million ounces, and that early expansion drilling results could bridge the gap toward two million ounces. Over a 10-12 year mine life, that scale supports a production profile in the range of 100,000-150,000 ounces per year, anchored by a future milling circuit targeting sulphide material.

Capital Structure and Path to Production

Axo Metals raised $40 million earlier this year and carries C$30 million in outstanding warrants that could be exercised on key catalysts such as permit receipt. The company estimates the remaining capital required to reach first production is modest relative to its treasury - management referenced peer Silver Tiger's capital build (approximately $100-130 million) as a comparable, while noting that San Antonio is approximately two-thirds already built, implying an incremental construction requirement potentially in the tens of millions of dollars.

This capital position, combined with the company's stated preference for non-dilutive financing instruments where possible, means Axo Metals is not under pressure to conduct a large equity raise ahead of a production decision.

September PEA: Scope and Market Positioning

The PEA due in September will cover the full San Antonio project's oxide heap leach, transitional material, and sulphide mill, providing a comprehensive view of the project's economics across development phases. Management has been explicit that the engineering work currently underway on the oxide component is being conducted to a higher standard than PEA-level confidence, because the intention is to proceed to a production decision - not merely to publish a study.

For the market, the PEA represents an opportunity to frame Axo Metals' enterprise value at around $100 million against projected first-year cash flows from a project that management believes can generate substantial returns even from its first phase. Ahead of that, the company will release further infill results from Sapuchi and the first step-out drilling results intended to begin demonstrating the broader scale of the San Antonio system.

The Investment Thesis for Axo Metals

• Brownfield advantage: Existing heap leach infrastructure including a 12,000 t/d crusher dramatically reduces construction risk and capital intensity versus a greenfield development
• Near-surface, low-strip starter pit: Sapuchi's geometry allows the company to start in ore with minimal pre-stripping, accelerating time-to-revenue
• Drilling upside: Infill holes are intersecting mineralisation in previously modelled waste zones, with potential to improve strip economics and the block model simultaneously
• Resource re-rating potential: The 2021 resource of ~1.1 Moz was estimated at sub-$2,000 gold; a mark-to-market re-run and expansion drilling could push this toward 1.5-2 Moz
• Compressed capital requirement: Management estimates incremental CapEx to first production in the "single tens of millions," well within the company's existing treasury
• Proven permitting group: Sister companies Silver Tiger and GoGold have both successfully permitted in Mexico under the current administration, providing a demonstrable pathway
• Valuation gap: At approximately $100M US enterprise value vs. projected first-year cash flows from Phase 1 oxide production, management sees a significant re-rating catalyst on the horizon
• Optionality on sulphides: The PEA will scope a future mill circuit targeting sulphide mineralisation, providing long-term upside beyond the heap leach operation
• Non-dilutive financing optionality: Modest incremental CapEx opens the door to debt, streaming, or royalty financing without requiring large equity raises

Macro Thematic Analysis

Gold's sustained elevation above $2,000 per ounce - and its trajectory toward and beyond $2,500 - has fundamentally changed the economics of assets that were previously marginal or stranded. For projects like San Antonio, where the existing resource was estimated at sub-$2,000 gold, this repricing is not cosmetic: it has the potential to convert previously uneconomic material into heap-leach-grade ore, reduce effective strip ratios, and extend pit shells.

"We're in an enterprise value today of like $100 million and the PEA comes out and it says well that's our cash flow for year one. That in itself is expected to be some kind of substantial re-rate."

Simultaneously, Mexico's Sonora state remains one of the more cost-efficient jurisdictions globally for open-pit drilling and development, with Axo Metals citing all-in drilling costs of $250 per metre. In a market where investors are actively searching for near-term gold production that does not require billion-dollar capital raises, the combination of brownfield infrastructure, in-country operator experience, and a rising gold price creates a rare alignment of factors. As Egilo summarised: 

TL;DR

Axo Metals is advancing San Antonio, a brownfield heap leach gold project in Mexico, toward a production decision, backed by existing infrastructure, a low-strip starter pit, and a proven permitting group. A September PEA will frame economics across oxide, transitional, and sulphide phases, while early drilling is already exceeding the existing block model. With ~$40M in treasury, modest remaining CapEx, and a resource re-rating potential from 1.1 Moz toward 2 Moz at current gold prices, the stock carries a credible near-term catalyst stack relative to its current enterprise value.
