Work History

Fairfield Minerals Ltd carried out reconnaissance prospecting and rock, soil and silt sampling prior to staking Mor cl 1-4 (YB89971) in Sep/97. In 1998 the company carried out grid soil sampling, ground magnetic and VLF-EM geophysical programs and minor blast trenching before adding Mor cl 5-8 (YB91626) and Mor cl 9-12 (YB91820) in Sep/98. In Apr/99 Fairfield staked Mor 13-52 (YB92029) before optioning the claims to Brett Resources Inc later in the year.
Brett Resources concentrated their efforts on exploring the newly staked claims. The company prospected and carried out a wide spaced soil sampling program on the new claims before relinquishing its option in Dec/99.
In 2000, Fairfield Minerals carried out additional grid soil sampling and ground magnetic and VLF-EM geophysical surveys. The company also used a portable power auger to collect more detailed soil and rock samples in the vicinity of the Discovery s

Capsule Geology

The area is located in the southeastern portion of the Teslin (105C) topographic map sheet. Geologists employed by the Ancient Pacific Margin NATMAP project; a projected jointly funded by the Geological Survey of Canada, the British Columbia Geological Survey and the Yukon Geology Program, are presently re-mapping the area, including the rocks in the occurrence area. Exploration interest in the region has recently risen as most of the rocks appear similar in age (Devonian ¿ Mississippian) and lithology to those hosting volcanogenic massive sulphide mineralization in the Finlayson Lake district.
The occurrence is located within the Big Salmon Complex a sequence of Late Devonian to late Mississippian deformed and metamorphosed rocks considered to be part of the Yukon-Tanana Terrane. Recent work by Roots et al., (2000) suggests that the stratigraphic order of units in the Big Salmon Complex is as follows: 1) greenstone; 2) crinkled chert exhibiting red to pink hues from hematite and piedmont; 3) buff-weathering white carbonate; 4) mixed metavolcanic/metasedimentary rocks, including graphitic metaconglomerate and meta-tuff layers; and 5) immature clastic metasediments. Numerous Mid-Cretaceous age intrusions of varying size are known to occur in the area.
Fairfield Minerals¿ initial reconnaissance program in 1997 uncovered the Discovery showing, described as quartz rich muscovite-sericite and chlorite-biotite schist hosting strongly disseminated to semi-massive pyrite, chalcopyrite and other minor sulphides. Follow-up grid soil sampling outlined a 2 000 m long by 100-250 m wide Pb, Zn, Ag and Cu soil anomaly. The ground EM survey outlined 3 EM conductors, one of which was coincident with the main soil anomaly. Grab and chip samples collected from trenches blasted into the showing returned assays up to 10 520 ppm Cu, 5 081 ppm Pb, 5 515 ppm Zn, 82.2 ppm Ag and 8 910 ppb Au.
Soil sampling carried by Brett Resources outlined a Cu soil anomaly in the eastern part of the property, however the widely spaced lines used in the survey prevented the company from properly analyzing the anomaly. Detailed geological mapping of the Discovery showing outlined several felsic horizons within enclosing mafic volcanics. Mapping traced these horizons over a strike length of approximately 900 m.
The auger sampling program refined the existing geochemical and geophysical anomalies located along the Discovery showing and located significant blind mineralization at two widely separated locations situated within this trend. Auger sampling of these new showings, which may represent new and previously untested felsic horizons, returned assays up to 1 226 ppm Cu, 5 724 ppm Pb, 466 ppm Zn, 109.2 ppm Ag and 2 139 ppb Au.
Mortensen and Gabites (2002), carried out lead isotopic studies in the region, including the Mor occurrence. A pyrite sample collected from felsic schist at the Discovery showing fell somewhat below the shale curve and yielded a broadly Devonian-Mississippian model age, consistent with the inferred age of the host strata and thus providing strong support for a syngenic origin (i.e. stratiform ) for this mineralization.
