Location and accuracy The 737 prospect is about 0.7 mile north of the terminus of the Saksaia Glacier at an elevation of about 3,200 feet. It is about 0.5 mile east-southeast of the center of section 34, T. 28 S., R. 54 E. The location is accurate.

Geologic setting

Geologic description

The 737 Prospect was first identified as a volcanogenic, massive-sulfide deposit by Constantine Metal Resources (2008); it is one of several along a well defined belt of similar Upper Triassic deposits that extend southeast for about 5 miles from unnamed prospects near the Jarvis Glacier (SK070), through the Little Jarvis Glacier prospect (SK069), the RW Zone (SK067) , the Main Zone prospect (SK066), and the 737 prospect, to the Red Creek prospect (SK063). Relatively little is known about the 737 prospect specifically although it clearly is similar to others along the belt. It is on a Pulse EM, geophysical anomaly that indicated a buried massive-sulfide deposit. One drill hole on the 737 prospect did not intersect mineralization but a surface sample collected across 0.5 feet of massive sulfides contained 12.0 percent zinc, 2.66 percent lead, and 47.6 gram of silver per ton.

Mineral deposit model Probably a Besshi- or Kuroko-type volcanogenic massive sulfide (Cox and Singer, 1986; models 28a or 24b).
Mineral deposit model number 28a or 24b
Age of mineralization Late Triassic; correlative with similar deposits nearby along a belt of massive-sulfide mineralization.
Alteration of deposit None specifically noted.

Production and reserves

Workings or exploration Sampled at the surface and covered by a pulse EM geophysical survey. One hole drilled in 1998.
Indication of production None
