Robinson-Lasher Showcases Zinc Potential
The Robinson-Lasher property, encompassing 1,524 acres in Livingston County, sits along the Robinson Fault, a near-vertical structure with 20,000 feet of total strike length. The property controls approximately 1,700 feet of the fault system, where bedded replacement deposits have been developed through a 1,270-foot decline to 240 feet vertical depth[39].
This property has undergone extensive exploration with 232 core holes to at least 9,855 ft with a historic resource of 70,000 tons grading 32% CaF2 (Bethel Horizon), 105,000 tons grading 30% CaF2 (Shetlerville Horizon) for 175,000 tons fluorite. (1, pp. 68–70). There is additionally another 387,225 tons grading 14% Zn in lower sub-Rosiclare with 5-10% fluorite according to an internal Dynamex company report[40],[41]. Total footage comes from a Boyce Moodie memo dated April 20, 19761. Dynamex exploration[42] demonstrated that 77% CaF2 grades are achievable in certain intervals, though typically over smaller thicknesses.
