Rebeico Copper-Gold Project in Sonora, Mexico

• Wholly-owned high-grade copper-gold project comprised of 3,459 hectares of privately-owned land. Property has multiple significant exploration targets including the Alaska Vein, the New Year Zone, the IP Anomaly, and a number of historic mines including the El Cobre copper mine.
• Drilling highlights include 19.3 metres grading 1.6% copper plus 1.8 g/t gold from surface and 1.0 metres grading 6.0% copper plus 17.7 g/t gold from underground.

Guadalupe y Calvo (GyC) Gold-Silver Project in Chihuahua, Mexico

• Option to acquire 100% ownership of an advanced-stage, high-grade gold-silver project spanning 2,750 hectares within a historic mining district with production of over 2.0 million ounces of gold and 28 million ounces of silver at an average grade 37 g/t gold and 870 g/t silver.
• Extensive historical exploration including drilling since 2003 plus geophysics and generative exploration work which has led to a historic Indicated Resource of 236,543 gold-equivalent ounces grading 3.95 g/t Au Eq plus an Inferred Resource of 16,713 gold-equivalent ounces grading 3.38 g/t Au Eq. The resource remains open for expansion both along strike and at depth.

Endeavour Silver Corp. reported in a technical report titled “Technical Report on the audit of the mineral resource estimate for the Guadalupe y Calvo project in Chihuahua State, Mexico” was prepared by Micon International Ltd. as of December 15th, 2012 the above historical mineral resource. For Ridgestone’s purposes, the estimate for GyC are considered to be historical estimates under National Instrument 43 101 (“NI 43 101”) as they were prepared by Endeavour before Ridgestone entered into the agreement to acquire the projects from Endeavour. A Ridgestone qualified person has not done sufficient work to date to classify these historical estimates as current mineral resources. Ridgestone is not treating these historical estimates as current and the historical estimates should not be relied upon. The mineral resource was estimated following the CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines, prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council on 27 November, 2010. The resource estimate was conducted using the Vulcan mining software to produce a three-dimensional resource model for the Rosario and Nankin veins. Gold equivalency is based on US$1,900 per ounce gold price and US$25.00 per ounce silver prices, assuming 100% metallurgical recoveries.

Copper has traded from a low of US$2.06 per pound in mid-2016 to a record high of US$4.30 per pound in February 2021. Gold has traded from a low of US$1,162 per ounce in late 2016 to a record high of US$2,058 per ounce in August 2020.

Demand from renewable power generation, battery storage, electric vehicles, charging stations and related grid infrastructure accounts for about a fifth of copper consumption, according to Citigroup Global Markets Inc. Citigroup made a huge call on the copper price for 2021 and 2022, forecasting $10,000 per metric ton (US$4.54/lb), with a "bull case" for $12,000 per ton (US$5.44/lb).

"The market now on the cusp of the tightest phase in what we expect to be the largest deficit in a decade" according to Goldman Sachs.

Gold is primed to benefit from global stimulus efforts, leading to low real interest rates, which will drive higher inflation.

CIBC is calling for gold to average US$2,100 per ounce in 2021 citing rising inflation as the dominant bullish factor for precious metals.
