Dateline Resources pledges to continue chairman’s US gold strategy
Dateline Resources plans to continue its US gold and critical minerals strategy after longtime chairman Mark Johnson died following a brief illness.
Johnson helped shape the company’s ambitions over 13 years, including its effort to reopen the Colosseum gold project in California.
The mine produced 344,000 ounces of gold before closing in 1993, and Dateline acquired it from Barrick Gold in 2021.
A feasibility study projects a 10.4-year operation producing 573,000 ounces, based on a reserve of 20.6 million tonnes of ore.
But a legal challenge to mining approvals dating back to 1985 has temporarily stalled development.
Dateline says it will press ahead, while the site’s rare earths prospects add to its critical minerals ambitions.
