ABOUT EXTER
Exter Gold Corp. (CSE: XGOL) is a Canadian exploration and gold production company uniquely positioned with an operational mill, producing mine and high quality exploration assets east of Mazatlán, Mexico, a region known for its rich mineral endowment and mining infrastructure. The company recently changed its name from Bird River Resources Inc. to Exter Gold Corp., and now trades on the Canadian Securities Exchange under the ticker "XGOL", a name change that reflects a sharpened focus on gold asset development and aligns the company more closely with its core growth strategy. Exter holds a robust portfolio of mining assets that includes high-grade exploration and production infrastructure, and is primed for resource expansion, discovery potential, and revenue generation.
MEXICAN OPERATIONS
Exter Gold holds 100% ownership of various gold projects on the eastern flank of the Sierra Madre Mountains, positioned on a prolific epithermal belt that runs from Jalisco, Mexico to Arizona, USA, one of the most successful gold mining zones in the Americas. Upon completion of its acquisition of Analog Gold assets, Exter Gold Corp. will be a new, fully integrated producing Gold and Silver mining company located in a Tier-1 mining district. These properties have excellent road access, positioning the Company for rapid exploration and resource expansion activities. In addition, Exter has secured a right of use option on a nearby processing mill, recently upgraded and successfully tested on ore, a key advantage for advancing toward production. Management, together with field geologists, is finalizing its exploration strategy and planning a drilling program in the near term, a major catalyst expected to unlock resource potential and drive valuation, with cash flow anticipated by Q2-2026.
STRATEGIC EXPANSION
Exter entered into a binding Letter of Intent to acquire additional Mexican mining assets from Analog Gold, including the Tres Oros Mine and the Tadeo Mill, a refurbished processing facility with a capacity of ~600 t/day that has already begun trial production with third-party ore (+40,000 tonnes processed since Q4 2025). This acquisition would substantially augment production capability and diversify the company’s asset portfolio. With Exter's strategic focus on high-potential gold and silver projects in a prolific mining region, and near-term cash flow potential through the Tadeo Mill and tolling agreements, Exter is well-positioned to create accretive value with a significant asset base of promising properties and a strategic mill.
