The Severance Property is located in the Klotassin River valley, 125 km west of Carmacks, Yukon, on NTS map sheet 115J/7. The property consists of 30 Quartz Claims staked in accordance with the Yukon Quartz Mining Act in the Whitehorse Mining District.
The property is underlain by granodiorite and monzonite of the Cretaceous Dawson Range Batholith. These rocks are intruded by Eocene quartz-feldspar porphyry dykes and plugs and are overlain by their volcanic equivalents, quartz-plagioclase porphyritic dacite, of the Skokum Volcanic Suite.
The earliest recorded exploration in the area was in the 1970’s, when Atlas Exploration Ltd staked claims in the area during the staking rush following the discovery of the Casino Porphyry deposit, 40 km to the north. Altas identified anomalous values of copper and molybdenum in an alaskite stock and found traces of molybdenite in quartz veins but did not follow-up on these results and the claims were later allowed to lapse. In 1986, the Geological Survey of Canada (GSC) conducted regional geochemical stream sediment surveying in the region. A sample, collected from small creek flowing into Somme Creek on the north side of the property returned 144 ppb gold and anomalous copper and molybdenum.
In 1998, Kennecott Canada Exploration Inc. conducted a reconnaissance soil and stream sediment sampling program in the area to follow-up on anomalous gold values from the GSC program. Their work outlined a gold anomaly >35 ppb, in excess of 2 kilometres long. However, Kennecott did not follow-up these results.
In 2002, 4763 NWT Ltd. staked the Severance claims to cover the area of anomalous gold-in-soils identified by Kennecott and conducted a program of soil sampling and prospecting. The soil sample program returned a number of anomalous gold values up to 2,680 ppb and anomalous copper and molybdenum. The prospecting program identified silicification and disseminated pyrite mineralization in monzonitic intrusive rocks with one sample returning 1.2 grams/tonne gold and 0.3% copper. Eagle Plains Resources Ltd. optioned the property from 4763 later that year.
In 2003, Eagle Plains conducted a regional stream sediment sampling program, expanded the soil sample grid and conducted 2.5 km of ground magnetic surveying. The following year, Eagle Plains further expanded the soil grid and the magnetic survey and conducted 5.4 km of Induced Polarization (IP) geophysical surveying. This work identified a coincident copper-gold-molybdenum soil anomaly that measures 800 m by 1200 m and is open to the east and west. Within this zone are values as high as 1966 ppb gold, 1036 ppm copper and 54.3 ppm molybdenum. These results were considered significantly anomalous. This zone is within a magnetic low and is underlain by a broad IP chargeability high. In 2006, Eagle Plains transferred ownership of the claims to Copper Canyon Resources Ltd. and in 2007 the property was optioned to Northern Freegold Resources Ltd. (now Triumph Gold Ltd.)
The suite of anomalous elements and their distribution is suggestive of an intrusion related or porphyry system. The IP chargeability and resistivity response is similar to that expected from a porphyry system.
