Greencastle Resources Ltd. Options Gold Property to Golden Lake

Jewel Ridge is located on the south end of Nevada's prolific Battle Mountain - Eureka trend, strategically along strike and contiguous to the former Barrick Gold, two million gold ounce Archimedes/Ruby Hill mine to the north and Timberline Resources' advanced-stage Lookout Mountain project to the south.

The property consists of 96 unpatented lode mining claims and 30 patented claims covering approximately 728 hectares (1800 acres). The Jewel Ridge property contains several historic small gold mines which align along a north-south-trending stratigraphic contact of Lower Paleozoic sedimentary rocks, as well as several other gold-mineralized zones with a variety of structural and lithological controls.

• Mineralization in the Eureka district, and on the Jewel Ridge property is mainly of two types; 1) Carbonate replacement deposits of Ag-Pb-Zn and Au, mined in the early days of the district, and 2) Carlin-style disseminated gold deposits, the primary focus since the late 1970's.

• Nevada "Carlin Type Gold Deposits" ("CTGD") have a combined endowment of more than 250 million ounces, which are concentrated (85%) from only four trends or "camps" of deposits: Carlin, Cortez (Battle Mountain-Eureka), Getchell, and Jerritt Canyon (Kitco, J. Graham, June 20, 2019).

• Based on the due diligence of an extensive data base of shallow RC drill holes, rock and soil geochemistry and limited geophysics, GLM feels the property has excellent potential for discovery of significant CTGD mineralization. The previous work represents millions of dollars of exploration expenditures and allows GLM to "fast-track" the vectoring of high priority drill targets.

• In addition to CTGD mineralization, GLM will investigate high grade silver values discovered in drilling in 2012 (hole JR-12-04, 601 grams silver per tonne or 21.2 ounces silver per ton (and 1.15 grams gold per tonne) over 3.0 meters from a depth of 15.2 metres).

• GLM is also planning to conduct state-of-the art airborne and ground geophysical surveys to aid interpretation and targeting. In recent years, there has been significant "break-thru" geological insights that have refined the "Carlin-type" deposit model, that can be applied on the Jewel Ridge property. A priority target is the South Eureka Tunnel zone, which has not been drilled since the 1980's, and the average depth of RC holes is only 78 meters.

"This marquee property acquisition in the heart of a prolific gold trend in Nevada gives Golden Lake year-round drilling capability and exciting potential for discovery of significant Carlin-type gold deposits," stated Mike England, president of GLM. "Gold mineralization at Jewel Ridge is present in a variety of styles over many target areas. In addition, GLM is engaging an experienced team of technical personnel, familiar with Nevada and Carlin-type deposits to aggressively advance the Jewel Ridge property."

GLM can earn a 100-per-cent interest in the Jewel Ridge property by paying Greencastle CDN $155,000 in cash, issuing 5.0 million GLM shares, and spending CDN $750,000 over three years. GLM will also cover the costs of the underlying lease (US $10,000 per year) and all BLM and county fees. Varying NSR's are applicable on the property with buy downs in place to reduce the NSR's to 0 and 1% on various claims and leases. A finder's fee may be payable in connection with this transaction.
