In 1909, the Alaska Gold Quartz Mining Company drove an adit 140 feet following the Granite Mountain vein. A 3-stamp mill was installed and operated part of the season. Operations were suspended, after ore changed from free-milling to base ore, pending installation of a concentrating table (Brooks, 1910).Web
