Work History
Staked as Dona cl 1-16 (YA9549) in Oct/76 by J. Edgar. D. Hermanutz staked Sleaper cl 1-6 (YB39958) 2.7 km to the southeast in Mar/91; restaked them as Sleaper cl 1-6 (YB40571) in May/92; and as Sleaper cl 7-8 (YB41918) in May/93.
Restaked as TPD cl 1-14 (YC07554) in Jul/98 by 17363 Yukon Inc.
In Mar/99 Prime Properties staked Mojo cl 1-20 (YC13249) 1.5 km to the south and subsequently optioned them to Prospector International Resources Inc. Prospector carried out prospecting and geochemical sampling later in the year and staked Mojo cl 21-36 (YC17436) contiguously to the northeast of the Mojo claims in Aug/99.
Teck Corporation staked Five cl 1-10 (YC17377)on the southeast boundary of the Mojo claims in Aug/99 and carried out a single line of geochemical soil sampling over the claims in 2000.
The occurrence itself was restaked as Flume cl 246-313 (YC17544) in Sep/99 by Phelps Dodge Corporation of Canada Ltd which carried out geochemical soil and rock sampling in 2000. The company focused the majority of its efforts in the area on other previously staked Flume claims further to the southwest (Minfile Occurrences #115N 110 and #115N 163). The Flume claims surrounding the occurrence lapsed in Sep/2002.
S. Ryan staked Dime cl 1-48 (YC86546) 1 km to the southeast in Apr/2009. Ryan added Dime cl 49-128 (YC86593) in Jun/2009. In Jul/2009 Ryan optioned the claims to Stina Resources Ltd for cash, shares and certain work commitments.
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.
Geological mapping by S. Gordey and J. Ryan shows the occurrence is underlain by a band of marble which is interlayered with more regionally extensive quartz-mica schist. North and south of the occurrence the rocks are intruded by Devonian to Mississippian tonalitic or intermediate to mafic orthogneiss. A large mid-Cretaceous biotite-quartz monzonite stock intrudes the sequence 4 km to the south. Eocene age quartz feldspar porphyry dykes likely also occur in the area.
Sampling on the Mojo claims, across a regional magnetic low feature that bisects the claims, returned a single station gold anomaly of 87.1 ppb. This sample also returned an arsenic value of 778.8 ppm. Samples collected over the center of the feature returned arsenic values ranging from 54.1 to 198 ppm.
Soil sampling by Teck on the Five claims (located to the south) and by Phelps Dodge on the Flume cl 246-313 returned a number of weak arsenic anomalies, but no significant gold anomalies. Rock samples collected from both claim groups did not contain anomalous values for either gold or arsenic.
