This Gold Explorer Is Making Its Biggest Bet | Brian Miller - Astra Exploration
- Top takeaway Brian views the early-2026 gold pullback as long overdue and potentially protracted, but still considers the broader bull market to be in "early innings" — volatility is, in his words, just what exploration lives with.
- He positions Astra as a pre-development, discovery-focused explorer built around epithermal gold-silver systems in South America, with a team that has made world-class discoveries before.
- On strategy, he is choosing between two viable target types at La Manchuria — narrow high-grade veins versus a bulk disseminated/open-pit model — based on where the fastest value can be realized to control dilution.
- He frames La Manchuria as an asset intended to be sold to a producer, with the JV's drag/tag-along clause giving a buyer a path to 100%.
- Brian says the next 12 months will be catalyst-heavy — 10,000 to 20,000 meters at La Manchuria and an inaugural drill campaign at the Chilean Don Mario project — backed by $12.5M in the treasury.
Gold's early-2026 pullback was long overdue, but the bull market remains in its early innings, Astra's CEO Brian Miller argues. Astra's La Manchuria project carries a built-in path to 100% ownership for any future acquirer through a tag-along provision. Astra's largest drill campaign — 10,000 to 20,000 meters — starts Q4 2026 to expand Manchuria Hill and test five new regional targets. Astra is also committing to an inaugural drill program at its Chilean Don Mario project, backed by a $12.5M treasury. Michael Gentile evaluates Astra by asking 'can there be a mine here' first, then weighing infrastructure and team credentials.
