Köppen climate type:
A former Ag-Zn-Pb occurrence/mine located in secs. 7 & 8, T15N, R9E, MPM. Latitude & longitude are general for the area.
NOTE: Political location in record is Judith Basin county. However, lat/long plot in Park county. Original coordinates for line#1 were: lat/long NAD27 46-5-N 110-37-W (46.08333 -110.61667); UTM N E Z; PLSS line# 1: Meridian- Montana Principal, T15N, R9E, Sec. 07,08, Sec._fract . PLSS translates to 47 04 32N, 110 37 13W. It is likely the reporter typed 46 deg lat instead of 47. Lat/long changed to center of PLSS Section 7, 8 using WGS84 datum. Oddly, the original coordinates are the same as for Hughesville 10008953.
Mineralization is a polymetallic deposit hosted in syenite. local rocks include Tertiary coarse-grained intrusive rocks.
Average Assay (1929): Pb = 6.21%; Zn = 5.01%; Ag = 0.09 ounce/ton.
