Project Description

About Romero

The Romero gold-copper deposit was discovered by GoldQuest in 2011 and represents one of the most significant mineral discoveries in the Dominican Republic in recent decades. The project is located within the Tireo Formation, a volcanic arc sequence that extends across central Hispaniola.

With over 118,000 meters of drilling completed, Romero hosts an Indicated Resource of 2.27 million ounces of gold equivalent (Indicated), with an additional 0.24 million ounces of gold equivalent in the Inferred category. The deposit is characterized by its amenability to conventional processing methods, with excellent metallurgical recoveries demonstrated through extensive test work.

A Preliminary Feasibility Study has confirmed robust project economics, positioning Romero as a compelling development opportunity with established infrastructure and an experienced local workforce.

Category	Tonnes	AuEq (g/t)	Contained AuEq	Contained Au
Indicated	20.23 Mt	3.48	2,265,000 oz	1,738,000 oz
Inferred	3.02 Mt	2.47	240,000 oz	197,000 oz

Romero Mineral Resource Estimate, effective September 27, 2016 (NI 43-101). Gold-equivalent (AuEq) grades and ounces. Mineral resources are not mineral reserves and do not have demonstrated economic viability. See the technical report for grades, cut-offs, and assumptions.

Pre-Feasibility Study · 2016

Robust Project Economics

Romero's NI 43-101 Pre-Feasibility Study outlines a high-margin underground gold-copper mine with strong returns — built on just 35% of the Indicated resource, leaving significant room to grow.
