December 9, 2025

 

Today we welcome Dave Erfle, founder and editor of Junior Miner Junky, to break down a big week in the resource sector. Two major M&A deals hit the tape while silver powered above $60/oz, adding fuel to an already strong precious-metals bull market.

 

Key Discussion Points

 

  • Dolly Varden Silver + Contango Ore Merger
    A cash-flowing US gold producer (CTGO) joins a high-grade silver explorer (DVS/DV.V). Dave explains why this de-risks Dolly Varden and brings retail strength and silver exposure to Contango.

  • How to Value the New Company
    With production, exploration, and sizeable free cash flow combined, Dave outlines why valuation becomes more complex.

  • Silver Over $60/oz
    Dave highlights technical targets, a falling gold–silver ratio, and why silver equities remain highly leveraged to the move.

  • Rio2 Acquires Producing Copper Mine
    Rio2 (RIO/RIO.V/RIOFF) adds immediate cash flow through a US$217M purchase in Peru, supporting its Phoenix Gold Project as it nears first pour.

  • Trend: Juniors Bolting On Production
    Dave notes this strategy – seen with Integra, Discovery Silver, and Heliostar – is becoming the go-to model for developers to avoid heavy dilution.
