Scheelite occurs in tactite along a contact between calcareous hornfels and granodiorite, and in a tactite bed about one foot wide interstratified in metasediments. The contact strikes NW and dips steeply. It is intersected at right angles by the hornfels which strikes NE and dips 45 SE. The contact is explored by prospect pits and an adit; the bedded ore zone- is explored by a shaft and several small stopes.

Development: In 1941-42 the property was operated by h. E. Hall, jim hall, and john jergenson. In 1943-44 the mine was leased t-o j. D. Upton and joseph wyckoff who operated it As the lake t-ungsten mine. A small tonnage of ore was mined from the toy cl-aim, part of which was sent to the metals reserve stockpile at- winnemucca and part was milled at the hall mill at toy. The p-roperty was again mined for a short time in 1953-1954.

Age: Phanerozoic (5.333 - 201.3 Ma)
Description: Poorly dated felsic intrusions described as granitic rocks, granite porphyry, granodiorite, quartz monzonite, and many undivided plutonic rocks are included here. They crop out in every county except Elko and northern Washoe.
