Project Overview

USGD acquired the permitted Madison Copper Gold Mine from Madison Metals June 2020

100% owned with US$6.8M spent on exploration since 2019

Past production 2008 – 2012 of 2.7M lbs of copper with grades ranging from ~20% to over 35% copper and 7,570 ounces of gold at 16.1 g/t

Analogous to and just 48 km from the Butte mine, which churned out 21 billion lb. copper, 715 million oz. silver, 2.9 million oz. gold

Copper-Gold in Montana, USA

American Pacific’s Madison Mine is a high-grade, past-producing, 100% owned Copper-Gold project in Montana, which the Company acquired in 2020.

For this transaction, American Pacific was selected as a finalist in the ‘Deal of the Year’ category in both 2021 and 2022 at the S&P Global Platts Global Metals Awards, an annual program that recognizes exemplary accomplishments in 16 performance categories.

Madison Project has Fortitude Characteristics

Fortitude deposit has 2.5M ounces gold

* Assumptions: $1.22 per pound zinc, $2.82 per pound copper, $16.26 per ounce silver, $1296 per ounce gold are the average of three years past and projected two years forward based on London Metal Exchange futures as of April 16th, 2019. Barite price of $220 per metric tonne provided by third party barite industry experts.


The project, a high-grade Cadia-like skarn over porphyry system, encompasses 2,514 acres consisting of six patented lode claims and 108 unpatented mineral claims. Recent interpretations identified multiple priority target areas believed to be associated with large-scale porphyry mineralization at depth and located within a well-mineralized, two-mile-long geological, geophysical and geochemical trend. The project is permitted for mining, surface and underground exploration.

The Broadway mine produced:


ounces of gold from 1880-1950


ounces of gold from 1880-1950 (Avg. of 0.52 oz/ton Au)


pounds of copper from bulk samples of 19,803 tons (Avg. of 25% Cu)

Approximately 3,000 total feet of underground workings go to a depth of 215 feet underground. Broadway Gold Mining Ltd. refurbished parts of the Madison Mine in 2017, rehabilitating the underground workings in order to access certain stopes and mineralization, allowing for a successful exploration drill program to take place as well.

Currently, known skarn mineralization, gold-bearing jasperoid and massive sulphide gold and copper mineralization is proposed to be linked to a deeper porphyry system.
