Ownership: 100% Candelaria Mining Corp.
Land Package: The Pinos Project consists of 29 mining concessions for exploration, mining, and production, totalling approximately 3,816 hectares. These concessions are held by Minera Apolo S.A. de C.V. (“Minera Apolo” or “Apolo”) and its subsidiary Minera Catanava S.A de C.V.
Description: The concessions which contain the Pinos Project consist of roughly 17km of mineralised veins containing gold and silver. The veins have been mined historically to a depth of only 180 meters, coinciding with the water table, but mineralization has been shown to continue at depth.
The Pinos mining district dates back to the XVII century. It was one of two bonanza gold districts discovered by the Spanish. Towards the end of the XIX century, the Cornish miners revived the district and continued mining throughout the Dorada era. Zacatecana Mining Company and Pachuca Mining Company operated the district between 1920 and 1940 where they mined more than 500,000 tonnes of mineral.
Location and Access: The Pinos Project is located in the central part of the Mexican Republic, adjacent to the municipality of Pinos, in the south-eastern portion of Zacatecas State, the second largest gold producing district in the country after Sonora. The Project is 80 km west from the city of San Luis Potosí and 140 km east from Zacatecas, the State capital.
The town of Pinos has accommodation and is a source of skilled and unskilled labour and basic supplies. Electric power and water are readily available in Pinos, along with gas stations, telephone, internet, bank facilities etc.
The nearest airport is in San Luis Potosí. Non-basic supplies can be easily sourced from the cities of San Luis Potosí and Zacatecas. Zacatecas State is well known for its availability of highly skilled personnel in mining and drilling.
Technical Report: A preliminary economic assessment was completed in September 2018 (see Candelaria News Release dated September 13, 2018), which envisioned an initial 200 tpd underground cut-and-fill operation ramping up to 400 tpd. The Company continues to optimize mining methods, the crushing circuit and grinding alternatives.
