Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Workings): Workings / Exploration = Surface prospecting was conducted prior to 1925 (Martin, 1922; Brown, 1926).

Comment (Reference): Primary Reference = Martin, 1922

Comment (Geology): Geologic Description = In 1920, a lode prospect was staked over a pyroxenite dike in limestone, which was uncovered in upper Hidden Creek (see MD066). According to Brown (1926), gold and copper carbonates are present. The Matthews and Blackburn vein lies within the pyroxenite dike, which is composed predominately of augite. The dike intrudes the Ordovician Telsitna Limestone formation (Dutro and Patton, 1982).

Comment (Deposit): Other Comments = See Hidden Creek placer (MD066). The Matthews and Blackburn prospect is on land conveyed to Doyon Ltd. For further information, contact Doyon Ltd. at 210 1st Ave., Fairbanks, Alaska, 99701.
