Tertiary Minerals reveals latest "incredibly compelling" silver results from Mushima North project

Tertiary Minerals reported its highest-grade silver-copper drill intersection to date at Zambia's Mushima North project: 82m grading 107 g/t silver equivalent from 8m depth. The interval contained 89 g/t silver, 0.20% copper and 0.38% zinc, including 37m at 165 g/t silver, 0.28% copper and 0.58% zinc. The strong near-surface mineralization is a positive exploration result that could improve the project's resource potential.

Analysis

The key valuation question is not grade but continuity, true width, metallurgy and recoverable ounces. A shallow, thick intercept can materially reduce strip ratio and development capex if replicated, but one reverse-circulation hole is insufficient to support a resource-grade tonnage estimate; AIM microcap explorers routinely see initial assay-driven reratings fade without systematic step-out confirmation. Liquidity in TYM is likely to amplify both directions, making the near-term move more a financing and drill-program trade than a mine-development valuation reset.

Over the next 1-3 months, follow-up holes that demonstrate lateral continuity across the mineralized horizon would improve the probability of a maiden resource and could lower the cost of future equity financing. Conversely, patchy grades, unfavorable silver-zinc metallurgy, or evidence that the intersection reflects a narrow structural zone would rapidly impair the implied economic narrative. The second-order positive is strategic: credible shallow silver-copper mineralization in Zambia could broaden the buyer universe beyond silver-focused juniors toward regional copper operators, although subscale zinc and copper credits alone are unlikely to drive economics.

Consensus may overvalue the silver-equivalent headline because the conversion assumptions, recoveries, payable terms and zinc contribution can materially alter equivalent grade. The more constructive contrarian case is that shallow geometry, rather than the headline grade, is the potential differentiator: if confirmed over a meaningful footprint, it can support lower-risk initial mining than deeper African polymetallic discoveries. No fundamental NAV-based target is defensible until tonnage, recovery and capital-intensity data are released.

Key Decisions for Investors

• Do not chase an opening liquidity spike in TYM; use a 1-3 month watch position only after the company publishes step-out assay spacing, mineralized footprint and a clearly funded drilling plan. Size as venture-exploration risk, not a silver-beta allocation.
• Add only if at least two follow-up holes confirm comparable true width and economically meaningful silver-equivalent grades at material offsets; this is the catalyst that can justify a resource-definition rerating rather than a one-hole promotion premium.
• Exit or avoid if subsequent drilling shows discontinuity, if metallurgical work indicates poor silver recovery, or if a discounted equity raise follows before resource delineation. These outcomes would likely compress both the exploration premium and financing optionality.
• For broader metals exposure, prefer liquid copper/silver vehicles rather than treating TYM as a direct commodity hedge; TYM's 6-18 month return will be dominated by geological conversion, permitting and dilution risk rather than spot silver or copper.
