Caprock Mining Corp. (CSE: CAPR) (“Caprock” or the “Company”) is pleased to announce that its technical team has discovered the presence of zinnwaldite, an extraordinary lithium-bearing mineral, during a recently concluded prospecting and sampling program on the eastern-most claim block (the “Main Claim Block”) at its Ackley Lithium-Tin-Molybdenum-REEs property (“Ackley”, or the “Property”) located in south-eastern Newfoundland, for which the Company has an option to acquire a 100% interest.
Caprock’s CEO Mr. Vishal Gupta states: “Historical work at Ackley returned assays of up to 0.91% lithium oxide, however the specific lithium-bearing mineral was never identified until an internal assessment of recently obtained samples by Caprock’s technical team. We are very excited by this discovery, since we believe that it is much easier and a lot less capital-intensive to produce lithium hydroxide from zinnwaldite than from the highly sought-after mineral, spodumene.”
Mr. Gupta goes on to say, “Zinnwaldite is being successfully mined and processed at the Zinnwald Lithium project in Germany, and its presence has only been documented a handful of times in Canada, previously. While it is still early days in our exploration work at Ackley, initial prospecting work indicates a potential for extensive zinnwaldite mineralization on the Property related to the large ‘greisen’ zone that resides at the contact between the Devonian-aged granite complex, and the Proterozoic metasediments and volcanics over which the Ackley claim blocks lie.”
Assay results from grab samples taken during recent field work will be published in subsequent press releases. The Company also awaits additional confirmation of the zinnwaldite mineralization through detailed petrographic analysis of the grab samples.
Additional Information About Zinnwaldite
Zinnwaldite is a potassium-lithium-iron-aluminum-silicate-hydroxide-fluoride phyllosilicate mineral within the mica group that typically occurs in greisens, pegmatites and quartz veins, and is often associated with tin ore deposits.
In general, zinnwaldite ore is the least energy- and capital-intensive hard rock mining alternative to a lithium-brine operation with respect to the production of lithium hydroxide, especially when compared to spodumene ore. Whereas spodumene concentrate must undergo two separate “high temperature” roast cycles prior to the production of lithium hydroxide, zinnwaldite concentrate only has to undergo a single “medium temperature” roast cycle in order to produce lithium hydroxide.
Additionally, unlike spodumene which has a tendency to lose its lithium content when exposed to ambient weather conditions, zinnwaldite is not subject to weather conditions as a means of production, which allows for greater certainty of supply and control of production.

About the Ackley Property
Ackley comprises three claim blocks that collectively span an area of 4,550 hectares located less than two hours’ drive from St. John’s. 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, that 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.

About Caprock Mining Corp.
Caprock Mining Corp. is a Canadian mineral exploration company focused on exploring battery metals in Newfoundland and precious metals in Ontario.
The Company has an option to earn a 100% interest in the Ackley Lithium-Tin-Molybdenum-REEs property located on the Burin Peninsula in south-eastern Newfoundland. Additionally, the Company’s 100% interest in several gold exploration properties gives it a substantial landholding in the historical Beardmore-Geraldton Gold Belt(“BGB”) of Ontario – a belt that has produced over four million ounces of gold historically, and contains the world-class Greenstone gold project (formerly known as the Hardrock gold project) which is being brought to production by a joint venture partnership between Equinox Gold (TSE:EQX) and Orion Mine Finance.
With an experienced management team that has a strong exploration pedigree, Caprock is poised to generate incremental shareholder value by advancing its portfolio of highly prospective exploration projects.
