The original mining operations (Old Helen Mine) were developed to mine the surficial secondary deposits of goethite with pockets of pyritic and quartz sands within the siderite and pyrite members. The Helen Mine was both an open pit and underground mine developed to mine the siderite ore body. Lying above the carbonate-facies is thinly bedded chert-wacke-magnetite iron formation. The mafic to intermediate metavolcanics of the hanging wall display well developed chloritoid porphyroblasts. The mafic metavolcanics are typically pillowed and are carbonate altered. The footwall consists of intermediate lapilli and crystal tuffs, and spherulitic flows. Coarse intermediate breccias are also commonly observed in the footwall.
History:
1897-99: A. Goetz, B. Boyer, J. Sayer - discovery, stripping, test pitting, driving adits. 1900: adit driven into mine hill, tramway for ore transport completed, open pit mining started, reported diamond drilling (3425 ft). 1901 - open pit mining to 168 feet, shaft No. 1 to 100 feet. 1902: No. 2 shaft sunk to 198 feet. 1903: No. 1 shaft to 168 feet; 3425 feet ddh. 1905- No. 1 shaft to 286 feet. 1906-09: No. 1 vertical shaft to 428 feet and 4 levels developed. 1910-15: No. 2 shaft deepened to 682 feet and 9 levels established, 4-compartment shaft sunk below level 4, inclined shaft completed to connect with 4th level; ddh of siderite ore. 1916-1917: ddh and trenching. 1918: 890 ft. adit completed to examine siderite zone, open pit mining ceases. 1937: new adit driven into Helen Iron Range. 1938: adit to 977 feet; surface trenching. 1939: open pit mining of siderite from Helen. 1943: No. 3 vertical shaft to 272 feet. 1946: Helen open pit abandoned. 1947: No. 3 shaft deepened to 921 feet, 3 deeper levels established, underground mining of Helen ored body begins. 1951: underground mining of Victoria Ore body, and discovery of Alexander ore body. 1960: mining of Helen ore body ceases.
