Key questions that remain
  • Is the resource figure supported by a current NI 43-101 / JORC technical report — and is it measured, indicated or inferred?
  • Is the stated grade a reserve grade, a resource grade, or a single drill intercept?
  • Which study do these economics come from — PEA, pre-feasibility or feasibility?
  • What metal price and discount rate underpin the NPV and IRR?

exploration upside 7 statements
West feeder extends approximately 750 m and is still open; system opened in every dimension spatially with additional fertile host rock units added
West feeder kind of extends how many meters now but 750 m or so, is that right? It's still open presumably.

high-grade gold and silver near surface, system wide open in every direction
Made new discoveries there recently. high-grade gold and silver near surface and a system that's wide open in every direction.
08 Mar 2026 ·
flagship asset is La Manuria
our flagship asset called La Manuria. very high grades near surface second year of exploration.
23 Jan 2026 ·
potential for multi-million ounce deposit
the original target the original thesis here is something that has potential for multi-million house deposit
23 Jan 2026 ·
system is not constrained, continues along strike in both directions, new parallel zones identified, additional potential at depth
this system is not constrained as was previously interpreted... the system does continue along strike in both directions. We've identified new parallel zones
23 Jan 2026 ·
It's got the potential to be a multi-million ounce asset
It's got the potential to be a multi-million ounce asset in areas with existing infrastructure.
17 Nov 2025 ·
potential to expand this into a multi-million ounce asset
This is a great opportunity to potentially expand this into a multi-million ounce asset.

deposit type 5 statements
high-grade gold-silver system near surface
our flagship property La Mantua in southern Argentina. High-grade gold silver system near surface
11 May 2026 ·
low sulfidation epithermal system
Lameuri is the project in Argentina and it is a low sulfidation epiothermal system.
08 Mar 2026 ·
big epithermal system with copper target
we have PMPA Paciencia which we did some drilling on a few years back. It's by Spence and Sierra copper mines. That's a big epiothermal system.
08 Mar 2026 ·
high-grade feeder system with near surface bulk disseminated deposit
presented a great opportunity to make a discovery like a high-grade feeder system a serenegrotype discovery.
08 Mar 2026 ·
high-grade precious metals (gold and silver)
We are focused on discovery of precious metals, high-grade precious metals, uh, in Argentina and Chile.
23 Jan 2026 ·
grade 2 statements
very high-grade gold, very high-grade silver, ounces of gold and kilograms of silver in open drill intercepts
very high-grade gold, very high-grade silver... I'm literally talking about ounces of gold and kilograms of silver in open drill intercepts near surface.
23 Jan 2026 ·
ounces of gold plus kilograms of silver in multiple drill intercepts
when I say high-grade, I'm literally talking about ounces of gold plus kilograms of silver in multiple drill intercepts that are open.

Every claim above was said by Brian Miller in the interview it is dated to, and carries their own words. Nothing is added from filings, and nothing has been checked against them. Transcripts are automated — clearly mis-heard words are corrected for readability, never figures, dates or the speaker's own hedges. Not financial advice: an executive discussing their own company has an interest in it.
