The Violet showing area is underlain by green and maroon mafic volcanics, volcaniclasitics and sediments. These rocks are similar to unit lJavb of the Lower Jurassic Hazelton Unit but contain a much higher component of interbedded wacke and may be transitional with the Upper Triassic Stuhini Group (unit uT-lJavb) (Open File 1997-3).
The showing occurs at the faulted contact between volcanic and sedimentary units and displays a gossanous alteration zone about 75 by 100 metres. Northeast dipping shear zones striking 300 to 310 degrees occur within the iron-carbonate alteration zone and contain discontinuous high-grade chalcopyrite-quartz lenses. Trench samples yielded highs of 5.79 grams per tonne gold and 3.76 per cent copper over a 0.98-metre length. (Assessment Report 21858, page 27). A 1990 diamond drill hole failed to intersect mineralization.
Northwest trending quartz-barite-chalcopyrite zones were located a few hundred metres to the west of the main showings but without associated gold.
Work History.
In 1989, based on GSC regional stream sediment sampling results, Ascot Resources Ltd. contracted Keewatin Engineering Inc. to carry out an exploration program including stream sediment sampling & limited prospecting over an area overlapping most of the Tatogga Lake Property. This program identified several zones with anomalous copper+goldĀ±silver, goldĀ±silver and copper+lead+zinc+silver. The Violet showing was first discovered in 1990 on the Axe property, held by Ascot Resources Ltd.
In 1990 and 1991 Ascot followed up this program with small ground magnetic & Induced Polarization geophysical surveys (near the Quash, Sun, Wolf and Trevor Peak MINFILE Occurrences), prospecting, geological mapping and extensive contour soil and rock geochemical sampling. Work reported done on the Axe claims in 1990 and 1991 (primarily rock, soil and silt sampling) was spread over a number of showings on these extensive holdings. The exploration was focused in nine primary zones: Trevor Peak, West Wolf, Seestor, Sun Plateau, Horn, Violet, Petal, GoNo and Central in the Quash-Pass area.
During 2011 through 2014, New Chris Minerals completed programs of prospecting, soil and rock sampling, geological mapping, a 14 line-kilometre ground induced polarization survey and 2379 line-kilometres of airborne geophysical surveys on the area as the Tatogga Lake project.
In 2017, GTGold Corp conducted prospecting traverses around the Saddle and Quash-Pass area, collecting 46 soil samples and 177 rock samples.
In 2018, GTGold Corp explored the Tatogga Property in 2018 with 24,759 of diamond drilling on the Saddle North and Saddle South prospects where both targets were reported to have intersected strong mineralization. IP surveys occurred at the Saddle North and Saddle South and over some parts of the Quash-Pass area about 9 kilometres to the southwest of the Saddle area. A total of 2254 line-kilometres of airborne magnetic and radiometric surveying covered the Saddle North and South Saddle areas and extended to the southwest covering the Quash (104G 161), Violet (104G 164), Petal (104G 165), Pass Gossan (104G 166) and Central (104G 167) occurrences.
See Saddle North (104G 432) and Saddle South (104G 433) for related geological and historical information on the Tatogga property.
