1954 Surface work by Horlac Mines Ltd. 1955 8 d.d. holes, aggregating 523 feet by Horlac Mines Ltd.

Two mineralized zones, striking about N45E, have been located
in flat-lying Keweenawan amygdaloidal lavas. The north zone, tested
by three drill holes over a length of 175 feet, consists of a steeply dipping body of calcite stringers over a width of about 30 feet. The
calcite stringers contain chalcocite, which also occurs as amygdule
fillings, and disseminated grains in the lava, between and bordering
the calcite stringers.
The south zone lies 400 feet southeast of the north zone. It is of
similar character and has been tested by five drill holes over a
length of 1,000 feet. The holes were all bored from southeast to
northwest at angles of 45* and intersected mineralized rock over core
lengths ranging from 11 to 26 feet.
