The property is situated within the Watson Lake mining district of the Yukon and approximately 275 km from Watson Lake. It is easily accessible by the all-weather Nahanni Range road, which leads to the Canada Tungsten mine located 8 km directly east of the claims. The claims lie along a 20 km linear trend and are separated into 2 blocks. The northern block is comprised of the Glen, Rubus, LH, Swag and Scheer claims and the southern block comprises the Glen, Zanzibar and the Red Bluff claims. Commander staked the 150 Glen claims in May of 2011 and entered into an option agreement for the other 127 claims with well-known Yukon Prospectors, Gary Lee, Ron Stack and Bob Scott. The property covers 5,900 hectares along the 20 km trend.
The area has continued to undergo a resurgence of interest, following the continued success of our neighbours to the south, Aben Resources and Northern Tiger Resources Ltd. Staking has advanced up to the Glenmorangie boundary and several camps were active along the Hyland valley during the exploration season.
2012 Field Program
In-fill geochemical sampling of the two anomalous zones was completed with the collection of 401 soil samples. 27 grab rock samples and 9 silt samples were also submitted for assay. The assay procedure was changed this year to include a fire assay on all rock samples and a heavier aliquot (25g) sample for soils. In addition, 9 HMC samples were collected. This has been found to be an effective way of discovering gold present in silt samples. These bulk samples have been submitted to Overburden Drilling Management. Further mapping was also carried out across the claims.
The results of the 2012 field season are summarised as follows:
2011 Field Program
The area was extensively mapped, and 1,396 soil samples, 159 rocks and 52 stream silt samples and 5 Heavy Metal Concentrate (HMC) samples were collected. All samples except for the HMC samples, were submitted to ALS Mineral Services labs, located in Whitehorse.
These results were announced in early 2012, the highlights of which can be summarised as follows:
Exploration History of the area
Following the discovery of the Canada Tungsten mine in 1954, exploration activities in the area increased. The following is a brief summary of known historical activities:
Gold was originally found by Prospector Gary Lee and his partners when panning a culvert on the Nahanni Road. They then traced this find upstream and found mineralised quartz veins. The veins are hosted in phyllites and argillites and source of mineralization was suspected to be from a buried intrusion of the Tombstone Plutonic suite. A regional airborne survey has been flown across the area and which highlights the strong north-west regional strain but spacing of the flight lines was too far apart to be useful at a property scale.
During 2009 and 2010, soil and rock geochemical sampling was carried out across the property under a YMIP program. In addition to sampling, a basic ground borne survey was carried out, using a VLF-EM instrument and a magnetometer.
The region falls within the Tintina Gold Province which stretches from Fairbanks in Alaska to the south western portion of the North West Territories. The province has been recognized as hosting intrusion related gold systems related to mid to late Cretaceous suite of intrusives, known as the Tombstone plutonic suites, for example, Brewery Creek deposit (13.3 Mt @ 1.4 g/t Au), and Dublin Gulch (Eagle deposit with an indicated 4.8 M oz of contained gold).
The area falls within the sedimentary package of the Selwyn Basin, which was an ancient deep sea basin lying westward of the shallower Mckenzie basin. These basins formed what is known as the Cordilleran miogeocline, defined as a westward thickening sedimentary prism that accumulated on the westerly sloping basement of Ancestral North America from the late Proterozoic to Jurassic time (Gabrielse 1991). Locally, the region has been separated into two distinct units by a large fault called the March Fault, which has been mapped along the little Hyland river valley. The basin is structurally bounded by the Tintina strike slip fault to the south west, and to the north by the Dawson thrust fault.
The rocks to the north east of this fault are called the Vampire formation, an upper Proterozoic to lower Cambrian aged sequence of dark brown, fine grained thinly bedded argillaceous sandstone and siltstone, with minor interbedded orthoquartzite, phyllite, slate and argillite. To the south west of the March fault lie thin to thickly bedded brown to green shales, fine to coarse grained sandstones, conglomerates, minor argillaceous limestone, phyllites, psammites and minor marble belonging to the upper Proterozoic to Cambrian Hyland Group. This Group is sub divided between the clastic sediments of the lower Yusezyu formation, and the shales of the upper Nachilla formation, which is regarded as contemporaneous with the Vampire formation. Further to the east and proximal to the Cantung mine, lies the Cambrian Rabbitkettle formation of the Mackenzie basin, consisting of platform carbonates.
Underlying and exposed at surface in some localities are mid Cretaceous aged plutonic suites, called the Tombstone Plutonic Suite (97Ma to 91 Ma). The suite consists of K feldspar, porphyritic, biotitic monzonite and granodiorite. These intrusives are recognized as the main source of gold mineralizing systems in the Yukon and Alaska, and have created several styles of mineralization, namely:
There have been at least 3 phases of deformation in the area. The March fault which runs parallel with the Hyland valley in a north-west direction has been recognized as a major decollement fault and during the closure of the Selwyn basin, the lower Yusezyu formation was thrust up with a north east verging direction, and possibly over the younger Vampire formation to the east. The timing of this is event is unknown but probably represents late Jurassic and early Cretaceous plate convergence. A phase of basin folding with large open similar folds followed, creating the Selwyn fold belt. At some period in the Cretaceous period, the March fault was re-activated as a sinstral strike slip shear, parallel to the Tintina fault. This allowed room for intrusive magmatism during the mid to upper Cretaceous and was followed by extensional rifting and faulting, which have been mapped in a north to north-east direction
The property has not been extensively mapped but has been recognized as being within the Vampire formation of the ancient Selwyn Basin. The Vampire formation is recognized as an upper Proterozoic to lower Cambrian aged sequence of dark brown, fine grained thinly bedded argillaceous sandstone and siltstone, with minor interbedded orthoquartzite, phyllite, slate and argillite. An exposed mid Cretaceous aged granodioritic intrusion is situated at the southern end of the claims.
Mapping to date has added some interesting in-fill data to the property:
