The Cart limestone occurrence is located 6 kilometres west of the community of Granisle.
Permian limestone outcrops over 4 kilometres along a ridge trending north-northwest, 6 kilometres west of Granisle. The limestone is faulted to the east, bringing it in contact with volcanics of the Upper Triassic Takla Group. Bedding strikes 153 degrees and dips 45 degrees northwest.
The deposit was sampled in 1988 by Equity Silver Mines Ltd. during a search for limestone for acid neutralization in their nearby mine. As a result of this a program of bedrock trenching was initiated in late 1989. A baseline trench of approximately 600 metres was bulldozed and seven cross-trenches were cut at approximate1y 100 metre intervals. In 1991, two bulk samples (100 kilograms) were collected from these trenches and were analyzed. In 1994, the property was explored by New Canim Resources.
Seven chip samples taken across widths of 5 to 7.5 metres over a strike length of 500 metres averaged 52.57 per cent CaO, 0.25 per cent MgO, 0.024 per cent Fe2O3 and 3.05 per cent insolubles (Industrial Mineral File - Equity Silver Mines Ltd., 1989).
In 2012, an aeromagnetic program was conducted over the Flute and Lannac (093L 190, 191, 243, 338) properties having a total area coverage is 813 square kilometres. This area included the Cart occurrence. Total survey line coverage is 4,444 line kilometres. A report on the survey Riverside Resources (BC) Inc is found in Appendix D of Assessment Report 33032. However, maps showing the Total Magnetic Intensity and First Vertical Derivative of TMI are found in Assessment Report 33707F. These maps indicate that the following MINFILE occurrences have been covered by the survey: TACHI (093L 144), GUESS CREEK COAL (093L 151), O (093L 163), MINE (093L 164), ALP (093L 167), THEZAR 75 (WEST) (093L 190), THEZAR 81 (EAST) (093L 191), CORTINA (093L 192), COUGAR (093L 193), TOTEM (093L 199), RED (093L 210), DONNA (093L 212), FG (093L 213), BADGE (093L 215), SAT (093L 224), PRO (093L 225), JILL (093L 242), JACOB (093L 243), CART (093L 306), CHRIS (093L 307), CALCITE (093L 308), GOLD DUST (093L 315) and SURATT (093L 338).
In 2012 and 2013, Riverside Resources (BC) Inc conducted a percussion drill program in a significant area north of Fulton Lake (Assessment Report 33707 and 34591). The purpose of the drill program was to penetrate glacial cover and test the bedrock in target areas to determine if further work including diamond drilling was worthwhile. Drilling was located on pre-existing access roads and trails. In 2012, a total of 96 vertical drill holes for 1997 metres at 93 sites were completed and in 2013 a further 77 vertical percussion drill holes totaling 1,655 metres were drilled. One hole (FLRC-13-026) occurs several hundred metres south-southeast of the plotted Cart location.
