Receive FREE Investor Deck:

The Contango Ore + Dolly Varden Silver proposed merger will create a new well-funded, high-grade silver and gold company. This merger unites four of the highest-grade silver and gold districts in North America, with assets ranging from cash-flowing production to advanced exploration which will allow investors to gain full exposure to a full pipeline of value creation projects.

The combined company will benefit from:

◉ Immediate cash flow from the producing Manh Choh Gold Mine (Alaska)
◉ Low-capex Direct Shipping Ore (DSO) development strategy
◉ Significant exploration upside across a multi-asset portfolio in Alaska and British Columbia

The transaction positions the combined entity among a scarce group of North American mid-tier silver-gold companies with scale, liquidity, and strong institutional support.
