The measured resource stands at 548,071oz AuEq, the indicated at 456,932oz AuEq, and inferred at 144,379oz AuEq.
Gold Springs' president and CEO Antonio Canton said the 1 million oz AuEq mark is the first of the company's major milestone objectives.
"Our team is now focused on the 2022 drilling programme to reach the 2nd milestone, as we have planned a new resource update and PEA for the end of the year. Our goal is to reach within the next two years the 3rd milestone and complete the mine permitting process," he said.
Gold Springs' executive vice president for exploration Randall Moore noted that the project covers about 8,000 hectares with 33 "high-potential"" gold targets, six of which host the current resource estimate and cover 15% of the property.
"I believe Gold Springs will get more and more attention from major mining companies as the resource continues to grow," he said.
Gold Springs is in the Great Basin of Western USA.
