Lab Report | Oct 6 Deep Dives on Sterling, Contango, Banyan, and Argenta

CEO.CA Oct 6, 2026 1:02:35

Summary

Sterling Metals' Sioux project near Batchewana Bay, Ontario delivered 44 metres of 1.02% copper equivalent (all metals valued as copper grade) from near surface.

Host Allan Barry Laboucan argues grade plus continuity — not grade alone — decides whether a discovery can realistically become a mine.

Contango Ore pairs roughly $100 million of yearly free cash flow from its 30% Mancho stake with very high-grade Lucky Shot drilling in Alaska.

Banyan Gold's 1.88 g/t gap-zone hit (grams per tonne — metal weight per tonne of rock) hints its two Yukon zones form one bigger pit.

Argenta Silver's broad 46-metre gold-copper intercept points to a porphyry (the deep intrusion that feeds epithermal silver veins) near its 50-million-ounce resource.

Key points on Contango Ore Inc

  • The host sees the roughly $100M a year in free cash flow he says Contango earns from its 30% share of the producing Mancho joint venture as the platform to grow into a much larger mid-tier producer, with expansion paid for from that cash flow.
  • New Lucky Shot drilling in Alaska returned 140 g/t gold over 0.63m and 18.16 g/t gold over 3.65m, extending the very high-grade vein system the host calls the company's next mine.
  • The results demonstrate continuity of the Coleman segment and constrain the previously mined zones, feeding an updated resource estimate targeted for the first half of 2027 and then a feasibility study on a five-year mine plan producing 40,000-50,000 oz of gold a year.
  • The newly discovered KM vein adds a further target, and the host expects consistent news flow from the underground program.
  • At a C$807M market value, he places Contango at the very start of phase 5 on the Lassonde curve, arguing its development-stage pipeline and exploration spending give it, in his words, a lot of blue sky toward mid-tier valuations.

Key points on Argenta Silver

  • A 46m intercept of 0.45 g/t gold and 0.19% copper at the Karman gold-copper target has the host thinking Argenta is touching the porphyry that, in standard epithermal models, feeds the silver system - early days, but exactly what he looks for.
  • The 50-million-ounce high-grade silver resource keeps expanding: a 100m step-out beyond the resource boundary hit 1,600 g/t silver over 4m, which the host says shows unusual continuity and a team that understands the system.
  • He highlights recent metallurgical work showing roughly 95% silver recovery - well above the 60-70% he says is common in silver - as removing what skeptics still call a key project risk.
  • At a $126M valuation he argues the market is paying close to nothing for a growing 50Moz high-grade silver resource in Argentina with road access and mining infrastructure already in place, calling it an undiscovered gem.
  • Massive surface alteration visible even on Google Earth, plus unassayed historical core now being resampled, convince him this is a big system being tested from every angle.

Key points on Banyan Gold Corp

  • The host is most excited by the 1.88 g/t gold intersection over 17.9m in the largely undrilled gap between Airstrip and Powerline, seeing potential for the gap to become one high-grade starter pit.
  • He stresses location: the Yukon project has road access, power running through it, nearby communities and even cell coverage, and he says you could not find a better-positioned site in the territory.
  • With a roughly 8-million-ounce open-pit resource he believes can grow much larger, over $80M in treasury, and a first PEA targeted for the fourth quarter of 2026, he expects the coming numbers to be very strong.
  • He calls Banyan a takeover target - few 8-to-10-million-ounce Canadian resources with full infrastructure exist - and expects any acquirer would pay a premium rather than let it slide into the development-discount window.
  • High-grade gold in the Airstrip footwall points to where the near-surface gold being open-pit mined could be coming from, giving the company new follow-up targets.

Rick Van Nieuwenhuyse's takeaways

  • Top takeaway He says he is highly encouraged by the Lucky Shot assays, which demonstrate continuity of the Coleman segment of the vein system and better constrain the location of the previously mined zones.
  • He argues the results are instrumental to an updated mineral resource estimate in the first half of 2027 and a feasibility-level study targeting a five-year mine plan delivering 40,000-50,000 oz of annual production.
  • He calls the newly discovered KM vein a significant addition and points to consistent news flow ahead from the underground program.
  • The host describes him as a very talented company builder who has built bigger companies before, and a top-notch developer, mine builder and operator whose heavy focus on exploration fits the view that drilling is the lifeblood of mining.

Tara Christie's takeaways

  • Top takeaway She says the 1.88 g/t gold intersection over about 18m - high-grade for an open pit - highlights the potential for higher-grade near-surface mineralization in the largely undrilled gap between Airstrip and Powerline.
  • She notes the Airstrip footwall results identify additional high-grade targets for follow-up.

Jeremy Niemi's takeaways

  • Top takeaway He calls hole 27 another encouraging result from a system that continues to get larger as they drill it.
  • He says he is particularly excited about the hole-to-hole continuity as the high-grade core zone extends west within a broader coherent envelope of copper mineralization.

Rachel Lee's takeaways

  • Top takeaway The host says she was busy at the Beaver Creek conference recording a batch of interviews that give viewers a leg up on their homework for the companies she covered.

Allan Barry Laboucan's takeaways

  • Top takeaway He profiles four juniors as undervalued for what they control, calling Sterling Metals and Argenta Silver undiscovered gems at current valuations, Banyan a likely takeover target, and Contango a free-cash-flow platform with room to become a mid-tier.
  • His recurring analytical rule is that grade plus continuity, not grade alone, makes a deposit - citing Sterling's hole-to-hole continuity and Argenta's 100m step-out hit as proof points.
  • He is extremely bullish on the long-term copper market on weak supply and growing demand, and also expects silver prices to strengthen.
  • He pushes a chase-the-source exploration method: find the feeder porphyry behind Sterling's horizontal high-grade layer and the lurking porphyry next to Argenta's silver system.
  • He repeatedly ties weak volumes and muted news reactions to poor digital marketing, saying Sterling and Argenta need to reach a broader audience, and reminds viewers he makes no buy or sell recommendations, only homework ideas.
