Work History

Staked within Willy cl 1-32 (YB39987), Loco cl 1-24 (YB40828) and Ann cl 1-22 (YB40577) between Jun/91 and Jun/92 by Nor-Court Sand and Gravel Ltd, which explored with bulldozer trenching, stripping and roadwork. Nor-Court added individual Gonzo (YB45077), Bot (YB45078), Roi (YB45079), Spike (YB45080), Crow (YB45081) and Pluto (YB45082) claims along Frisco Creek. The company also staked Derek cl 1-4 (YB45063) on the peak of Mt Stewart in Jul/93.
M. Ellis staked Todd cl 1-4 (YB94569) on the peak of Mt. Stewart (4 km to the east) in Sept/96. Ellis staked Parker cl 1-16 (YB94573) 3 km to the north at the same time.
Restaked within White cl 200-303 (YC75721) in Jul/2008 by Underworld Resources Ltd as part of their White Gold project. In 2008 and 2009 the company carried out large exploration programs on the White Gold property. In 2009 the claims located west of this occurrence (and west of Frisco Creek) were grid soil sampled while the claims located east of the occurrence (and east of the creek) were reconnaissance soil sampled along ridges and spurs.
In Mar/2010 Kinross Gold Corp announced a proposed acquisition of all shares of Underworld Resources with the aim of acquiring control of the White Gold deposit and Underworld’s various exploration properties located in the Dawson region of the Yukon. In Apr/2006 Kinross announced its successful acquisition of 87% of the issued and outstanding common shares of Underworld Resources. Kinross immediately took steps to acquire the remaining shares of the company and on June 30, 2010 took Underworld Resources private resulting in Underworld Resources becoming a wholly-owned subsidiary of Kinross.
As a privately held company Underworld is not required to release exploration results. According to Yukon Exploration and Geology 2010, Kinross spent $14 000 000 exploring on both the White Gold and JP Ross properties (Minfile Occurrence #115O 160) located approximately 28 km to the northeast. Property-wide geological mapping, airborne geophysical surveys, soil sampling survey and over 25 000 m of diamond drilling was completed on the two properties.

Capsule Geology

The geology of the Stewart River Area was remapped by J. Ryan and S. Gordey (2004) of the Geological Survey of Canada beginning in 2000 as a component of the Ancient Pacific Margin NATMAP Project. The NATMAP Project is an interagency project initiated by the Geological Survey of Canada, Yukon Geology Program (now Yukon Geological Survey) and British Columbia Geological Survey Branch to understand the composition, relationships and metallogenic of poorly understood pericratonic terranes lying between the ancestral North American margin and those known with more certainty to be tectonically accreted. The Stewart River component focuses on the Yukon-Tanana terrane, comprising complexly deformed mostly (?) Paleozoic meta-igneous and metasedimentary rocks. In 2005 S. Gordey and J. Ryan released a geological compilation map for the Stewart River area. The map units generally remained the same as the 2004 geology map but age dates were changed to reflect new dates obtained through geochronology data.
J. Ryan reported that the Stewart River area is underlain by twice-transposed, amphibolite-facies gneiss and schist of mostly (?) Paleozoic age. These are intruded by younger plutonic rocks (Jurassic, Cretaceous and Eocene) and overlain by upper Cretaceous volcanic rocks. Metasiliclastic rocks are widespread and dominated by psammite and quartzite, with lesser pelite and rare conglomerate. Preliminary detrital zircon geochronology and geochronology for plutonic rocks constrain the siliclastic rocks to the Middle Paleozoic. Amphibolite interdigitates with and stratigraphically overlies the siliclastic rocks. Marble horizons ((?) reefs) occurs within the amphibolite and siliclastic rocks. Orthogneissic rocks with diorite, tonalite and granodiorite protoliths intrude both the siliclastic and amphibole assemblages; it is interpreted as a subvolcanic intrusive complex.
The occurrence area is underlain by Devonian to Mississippian quartz-mica schist. To the west broadly contemporaneous amphibolite interdigitates with and lies structurally (and possibly stratigraphically) above the schist. Extensive orthogneiss intrudes both units to the east. S. Gordey and J. Ryan's map shows an apparent fault separating this area from the neighbouring Golden Saddle and White-Arc (Minfile Occurrences 115O 165, 166) mineralized zones.
No detailed mapping has been released by Underworld Resources for the area around this occurrence. Soil sampling in 2009 did not locate any significant gold anomalies in the vicinity of this occurrence. Kinross Gold has not released any detailed data since their successful takeover of Underworld Resources.
