Work History
Union Miniere Exploration and Mining Corporation Limited (UMEX) and Shell Canada Resources Ltd. first staked the Monster property as the DAS (1-42) and ID (1-72) claims in 1975. Regional geological mapping and soil sampling with Cu and Co analysis was performed in 1976 by UMEX over the DAS claims. The claims were briefly optioned to Rinsey Mines Ltd. in 1990; however, no work was performed.
The ID claims were re-staked as Monster cl 41-72 (“Monster East”) in 1993 by Pamicon Developments Ltd. and Equity Engineering Ltd., who also re-staked the DAS claims as Monster cl 1-40 (“Monster West”). Monster Joint Venture optioned the claims in 1993 and performed geological mapping, prospecting and soil sampling over the entire Monster property.
Pendisle Resources Ltd., previously Monster Joint Venture, staked in Monster cl 73-265 in 1994 between the Monster East and West properties to create a contiguous claim block. They performed limited geological mapping and prospecting over the Monster East. The Cookie claims (1-20) located 2.5 km to the east-southeast of the Monster were also staked in 1994 and geological mapping, prospecting, and silt and soil sampling were carried out at this time across the Cookie claims.
In 1996, Blackstone Resources Ltd. (formerly Pendisle Resources) carried out helicopter-borne magnetic and radiometric gamma-ray geophysical surveys over the Ogilvie Mountain breccias, including the Monster property (Monster and Cookie claims). In 1998, Blackstone staked the Cookie cl 21-58 to the south and west of the original claims to create a contiguous claim block with the Monster claims, called the Monster property. Blackstone carried out prospecting and soil sampling over the entire Monster property during the 1998 exploration program to target magnetic and structural features outlined in the 1996 geophysics.
Blackstone Resources changed its name to Blackstone Ventures Inc. in 2001 before announcing a purchase agreement with Monster Copper Resources Inc., a private exploration company, who obtained a 100% interest. Monster Copper carried out geological reconnaissance, mapping, ground magnetic geophysics, and prospecting over the central and eastern portions of the Monster property in 2001. A similar work program was carried out in 2002 over the central and western portion of the property, which included mapping, ground magnetic geophysics, and rock geochemistry. Further gravity surveying was performed in 2003.
In 2007 Monster Copper Resources Inc. analyzed 1071 pulps of soil and rock samples collected by Blackstone Resources between 1993 to 1998 for U.
Go Metals Mining Corp., previously known as Gorilla Minerals and Go Cobalt Mining Corp., purchased the Monster Property in 2017 and performed geological mapping, soil sampling, prospecting, airborne magnetic and radiometric geophysical surveys and a Remote Spectral Geology (RSG) study over the entire property in 2018.
Regional & Property Geology
The Monster Property is centered on the Wernecke Breccia. The Wernecke Breccia are a 1.6 Ga set of megabreccias that occur over an area of 150 x 300 km in central Yukon. The breccias are variably IOCG altered and mineralized. The breccia zones were correlated to IOCG deposits on southern Australia based on lithological and temporal similarity (Thorkelson et al., 2001; Verbaas et al., 2018). The Wernecke Breccias in the Ogilvie Mountains were originally termed the Ogilvie Mountain Breccia (Lane, 1990), until Thorkelson et al. (2001) correlated both breccia sets and termed them the Wernecke Breccia in their entirety.
The Champagne showing occurs at the contact between dolomite and shale/wacke. The showing is 20 m wide on surface and extends over a 25 m long strike length (AR093965). Anomalous soil samples 300 m to the northeast of the Champagne showing suggest the zone may be continuous to the northeast (AR093965).
Mineralization & Results
Mineralization at the Champagne showing is present as blebby to fracture-controlled sulphides with minor malachite, azurite and erythite on fractures. This mineralization is localized in the dolomite along the contact with a possible zonation consisting of cobaltite to chalcopyrite ± bornite (AR093965).
Soil sampling over the Monster East (DAS) claims by Union Miniere Exploration and Mining Corporation Limited (UMEX) in 1976 yielded anomalies of Cu > 480 ppm and Co > 110 ppm.
Rock geochemistry of float and grab samples in 1998 by Blackstone Resources returned samples with anomalous copper and cobalt, including a sample with 7030 ppm Cu and 1795 ppm Co.
Analysis in 2007 by Monster Copper Resources of pulps of soil and rock samples collected by Blackstone Resources between 1993 and 1997 for uranium yielded up to 32 ppm U.
