Mar 18, 2011 (J Scott) - 0.50 oz/t Au in quartz veins cutting iron formation
Nov 28, 2017 (Mark Puumala) - The following description of the Geddes Lake gold showing is excerpted from AFRI 52H03NW0010: The main showing is auriferous iron formation located at or near the contact of the metavolcanics and metasediments. The surface expression is approximately 2 to 3 m wide and consists of 3 distinct units: a vein quartz unit with pyrite, a chert (+ minor pyrrhotite) unit and a banded magnetite unit. The showing has a surface strike length of approximately 100 m and a probable strike length of 1500 m. The iron formation strikes approximately N60E and dips steeply to the north. Mineralization occurs mainly as pyrrhotite and pyrite with trace to minor amounts of chalcopyrite. Arsenic assays show very few samples to carry more than 10 ppm with the majority being less than 5 ppm. Anomalous gold assays are associated with the iron formation which returned assays up to 5.45 ppm over 1.55 m in drill core and up to 16.7 ppm in grab samples from the trenches.
Nov 28, 2017 (Therese Pettigrew) - Egner and Curran report assays of 2900 ppm and over 10,000 ppm Zn from a vein in DDH x-23-2 (AFRI 52H03NW0003).

Geologist: Therese Pettigrew
Notes: The showing was visited on Aug 31/18 by RGP staff M. Puumala and T. Pettigrew. Three of the four Canamax trenches were located. Trench T-1 is at NAD83 UTM Zone 16 329039 m E, 5446168 m N. Trench T-2 (the largest trench and the main showing) is at NAD 83 UTM Zone 16 329064 m E, 5446180 m E. Trench T-4 is at NAD 83 UTM Zone 16 329124 m E, 5446203 m N. The vein in T-3 is hosted in sheared mafic metavolcanics that have strong carbonate alteration and abundant pyrite which occasionally had a sugary texture. In T-4, the zone is hosted in an iron formation that contains some magnetite. Quartz bands contained sulphides. Samples taken by M. Puumala from the main trench (T-2) assayed up to 0.058 oz/t Au (1.80 g/t Au).
