Caprock Mining Corp. announced the results of a high-resolution, drone-based magnetics survey that was recently completed at its Ackley Lithium-Tin-Molybdenum-REEs property located in south-eastern Newfoundland. Conclusions from the survey include: There is an extensive greisen zone directly associated with a large area of magnetic low at the contact between the intrusive granite and the meta-volcanic/meta-sedimentary country rock; The zinnwaldite mineralization so far identified from limited prospecting in this area occurs on the northern side of the contact between the intrusive granite and the large greisen zone; Zinnwaldite appears to be more directly associated with the intrusive granite but occurs proximal to the greisen zone; Both the greisen zone, and the contact between the granite and the greisen zone, were largely untested by the limited number of exploratory holes drilled in this area historically.

An Airborne UAV survey using RTK terrain following was performed over the main greisen alteration zone covering the Deer Pond area and its vicinity during September 2023. The survey was laid out to cover the target area with flight lines in both the north-south as well as the east-west directions in order to allow for a more detailed magnetometer map to be produced. Ackley comprises three claim blocks that collectively span an area of 4,550 hectares and is located less than a two hour drive from St.

John's, NL. The claim blocks overlie portions of the contact zone of a large Devonian-aged granite complex with Proterozoic metasediments and volcanics, parts of which are "greisened", or hydrothermally altered, and is similar in age and lithology to the Mount Pleasant deposit in New Brunswick and the East Kemptville deposit in Nova Scotia. Limited historical exploration work across the Main Claim Block by companies including Esso Minerals, American Zinc, Inco, and others discovered occurrences and anomalies of lithium, tin, molybdenum, tungsten, and REEs.

Recent magnetometer survey work over part of the Main Claim Block indicates that the altered contact zone may be extensive, covering several square kilometres. Recent limited prospect sampling and historical Esso trenches across the Main claim block returned assays of up to 0.91% lithium oxide, 5.0% molybdenum, 0.67% tin and 1-5% fluorine on surface. Newfoundland government survey maps of this region report some of the highest lake sediment values for REEs on the entire island.
