The Motherlode occurrence is located just upstream from the big bend in the Germansen River and is found on both sides of the river (Assessment Report 3956).
This occurrence is composed of sulphide (tetrahedrite, chalcopyrite and pyrite)-bearing quartz veins found within phyllites of the Middle to Upper Triassic Slate Creek Formation (part of the Middle Triassic to Lower Jurassic Takla Group). The veins are up to 1 metre in width and strike 120 degrees, dipping 70 degrees to the west. These veins cut across the dominant northwest striking and steeply dipping foliation. The rocks around the veins vary from weakly carbonatized phyllites, containing ankerite porphyroblasts, to mariposite-ankerite-quartz-sericite schists. These rocks are cut by shear zones parallel to the foliation, and close to the showing are in fault contact with carbonatized mafic and ultramafic rocks. These rocks lie within the right-lateral Manson fault zone of probable Cretaceous to Tertiary age.
Grab samples assayed 1.68 grams per tonne gold and 267.67 grams per tonne silver (Assessment Report 8956).
In 1972, Sullivan and Rogers of Toronto sampled anomalous gold, silver, copper and zinc from soil and rock geochemistry and outlined two large anomalous trends on the current QCM claims. This geochemistry program was followed up later in 1972 by IP and resistivity surveys. This work extended over 100 km of grid lines and resulted in two extensive anomalous gold trends.
In 1973, Rio Tinto optioned the claims and completed six diamond drill holes (499.56 metres). The results of this drilling were not filed but it has been reported that one of the drill holes, which intersected the more easterly of the two major carbonate alteration zones, yielded a 0.79 meter wide zone grading 4.25 g/t gold. Claims in the area lapsed, and were re-staked in 1979 by Vital Mines; these were allowed to lapse just one year later.
In 1980, Golden Rule Resources of Calgary staked the QCM claims and contracted Taiga Resources to complete geological mapping, soil and rock geochemistry, as well as a limited ground magnetic and ground VLF-EM survey. Their work is summarized under OPEC and QCM claims.
Anaconda Canada optioned the Manson Creek Property from Golden Rule in 1982 and carried out extensive geological mapping, detailed soil and rock geochemical sampling, ground magnetic and VLF-EM surveys and trenching. This work delineated two zones, the Flag showing, which is now called the Motherlode or Flagstaff, and the Central showing, which is now called the QCM. The QCM is 200 meters by 300 meters and open to the southeast with gold in soils ranging from less than 10 ppb to 4200 ppb. Bedrock below and around the Central Zone consists of quartz-carbonate altered epiclastics of the Takla Group. A 32 percussion drill hole program followed but the work was not filed for assessment A 4 reverse circulation drill hole program including 414 meters of drilling which was filed (Assessment Report 11627) and a 3 NQ sized diamond drill hole program including 422 meters of drilling which was not filed. The results of the percussion and diamond drill program were briefly summarized in later assessment reports numbered 19594 and 24349. In 1992, Golden Rule allowed the claims to lapse.
Mike Fox, who worked on the property for Golden Rule since 1980, staked the Au 1-12 two-post claims in 1993. Fox completed a program of re-mapping, analysis of existing data, and re-evaluation of the controls of mineralization in late 1994 to 1995. Four line kilometers of grid line were reestablished to provide ground control. This program concluded that a significant potential gold resource, of 0.6 g/t gold extending over an area 300 meters long by 130 meters wide by 80 meters deep, justified further exploration on the property.
Pursuant to an option agreement between Royal County Minerals Corp. and Viceroy Resources Ltd. dated October 04, 2002, the Canadian Gold Hunter Corp earned a 100 per cent interest in the Manson Creek QCM bulk tonnage gold property. The property includes the QCM (MINFILE 093N 200) and Motherlode (MINFILE 093N 024).
In 2004, the property was evaluated by Canadian Gold Hunter Corp. The company completed a 34 line-kilometre Induced Polarization survey that outlined a north-northwest trending zone with low chargeability and high resisitivity characteristics. Five diamond drill holes totaling 1190 metres tested a 375-metre strike length of the coincident anomaly. Three of the five holes drilled in 2004 intersected low grade gold mineralization over broad intervals.
In 2005, the QCM property was again drilled by Canadian Gold Hunter Corp. A total of 1802 metres in 9 holes evaluated carbonate altered, quartz veined pyritic greywacke of the Triassic Slate Creek Succession (Takla Group) and returned a best intersection of 0.58 gram per tonnes gold over 137.2 metres (Exploration and Mining in BC 2005, page 48).
