Orosur Mining Reports Q1 2025 Results with Focus on Colombian Gold Prospects and CAD$20M Fundraising

Q1 2025: Orosur doubles down on Colombian gold and shores up cash with CAD$20m raise

Orosur Mining has released its unaudited Q1 results to 31 August 2025. The quarter was light on P&L fireworks, but big on strategy: commit to a potential maiden Mineral Resource Estimate (MRE) at Pepas in Colombia, kick off drilling in Argentina, and exit Nigeria. Post period, the company also completed an oversubscribed CAD$20 million placing at CAD$0.34 with no warrants attached.

All figures below are in US$ thousands unless noted.

Colombia: Pepas targeting a maiden resource, with APTA and El Cedro in the wings

Pepas infill drilling aimed at a Mineral Resource Estimate

On 14 July 2025, Orosur formally started a work programme at the Pepas gold prospect (part of the Anzá project) designed to allow a Mineral Resource Estimate to be calculated. An MRE is the first formal statement of in-ground ounces under industry standards – a key de-risking milestone for any explorer.

The call was driven by external conceptual studies suggesting Pepas’ geometry and location, coupled with record high gold prices, might support nearer-term production options. Infill drilling ran through the quarter and after period end; if successful, expect a maiden MRE followed by economic studies focused on production at Pepas. Wider exploration, including at APTA, would then resume.

El Cedro porphyry: soil programme 90% complete

Early-stage work continued at El Cedro, a large gold porphyry target on the same licence as Pepas and APTA. The previously weather-delayed ridge-and-spur soil campaign restarted and is now 90% complete. Historical geophysics is being reprocessed, with new data to be acquired if warranted.

Argentina: El Pantano JV advances to phase two with drilling imminent

Orosur completed phase one of the El Pantano joint venture in Santa Cruz, earning 51% of Deseado Dorado S.A.S after investing US$1 million over three years. Phase two is now underway: invest a further US$2 million over two years to move to 100% ownership of Deseado.

Upon reaching 100%, the vendors retain a 2% NSR royalty (net smelter return – a royalty on sales revenue), half of which (1%) can be repurchased by Orosur for US$1 million. A geophysical campaign finished in the quarter and a 3,000 metre diamond drill programme is about to start. Clear, near-term catalysts here.

Nigeria: lithium exit to focus capital where it counts

Given weak lithium prices and the need to prioritise capital and people, Orosur is withdrawing from Nigeria in the coming weeks. The investment was already fully impaired as at 31 May 2025, so no fresh financial hit in Q1. Strategically, this simplifies the story around precious metals in South America.

Financial snapshot: cash rebuilt post quarter, modest loss in line with exploration stage

Metric	Q1 FY26 (to 31 Aug 2025)
Cash at period end	$3,906
Cash as at MD&A date incl. placing	$17.2 million
Total assets	$9,279
Total liabilities	$2,894
Total equity	$6,385
Exploration & evaluation assets	$4,632 (May 31: $3,858)
Net loss (total)	$(718) (Q1 FY25: $(279))
Corporate & admin costs	$(398)
Exploration expenses (expensed)	$(61)
Operating cash outflow	$(600)
Investing – exploration spend (cash)	$(554)
Financing inflow	$174 (warrant exercises)
Weighted average shares	314,235,630

Losses were modest and typical for an explorer: admin $398, exploration expenses $61, share-based compensation $73, and a non-cash fair value loss on warrants of $79. Foreign exchange produced a $74 loss. Note that much of the project spend is capitalised into exploration and evaluation assets (up to $4,632), which is why the expensed exploration line is relatively small while cash investing outflows were $554.

Fundraising: oversubscribed CAD$20m placing at CAD$0.34 with no warrants

After the quarter, Orosur completed an upsized brokered private placement, raising gross proceeds of CAD$20 million on 2 October 2025. The placing price was CAD$0.34 per share for up to 58,823,530 new shares, and importantly, no warrants were attached. The company says the placing was oversubscribed.

Why this matters: the raise materially strengthens the balance sheet (management cites $17.2 million cash including the placing) and funds the push towards a maiden resource at Pepas and drilling in Argentina. No warrants lowers future overhang. The trade-off is dilution from the new equity. The exact number of shares issued was not disclosed beyond “up to” 58,823,530.

Outlook: catalysts, execution risks and what to watch

• Pepas MRE pathway – infill drilling is ongoing. A timeline for a maiden MRE is not disclosed, but it is the central near-term value driver. If the numbers stack up, economic studies on potential near-term production would follow.
• APTA prospect – exploration drilling to resume after Pepas work; potential for a resource estimate is being investigated, but timing not disclosed.
• El Cedro porphyry – soil programme almost complete; reprocessed geophysics could define fresh targets.
• El Pantano drilling – a 3,000 metre diamond programme is about to commence. Early drill outcomes will shape how quickly Orosur pursues the path to 100% ownership.
• Funding runway – the CAD$20 million raise improves liquidity. The company has historically depended on access to capital; that risk is mitigated for now but never disappears for explorers.
• Warrant liability noise – a $1,785 warrant liability produced a non-cash $79 fair value loss this quarter. Expect some P&L volatility from this line as prices move.

My take: a cleaner, better-funded South America gold story

Q1 itself was steady: a small loss, some capex into the ground, and cash dipped as expected before being topped up significantly post quarter. Strategically, the moves are clearer and, in my view, positive. Focusing capital on Pepas with an eye to a maiden MRE – and explicitly considering near-term production options at today’s gold price – could crystallise value faster than a pure regional exploration strategy.

Argentina adds a second, tangible catalyst train with drilling about to start and a straightforward path to full ownership. Exiting Nigeria removes distraction and commodity risk tied to lithium prices. The raise was clean – no warrants – though dilution is the obvious trade-off.

Net-net, Orosur enters the autumn drill season with more cash, fewer distractions and two shots on goal. Delivering a credible MRE at Pepas and early drill hits at El Pantano would be the headline makers. Until then, it remains an exploration story – higher risk, but now with the funding to have a proper go.
