With the rise in the price of gold over the past year, precious metals exploration has picked up steam worldwide. Below we feature eight companies across the exploration, development and production spectrum that maintain a focus on discovery. 

Compass Gold

Compass Gold (TSXV: CVB; US-OTC: COGDF) is focused on the Farabakoura gold discovery in southern Mali. The company wholly owns the 850-sq.-km Sikasso project consisting of nine permits within the Birimian gold belt.

Farabakoura is a 15 km long target area that traverses the company’s Faraba-Coura, Ouassada and Sankarani permits.

In September, Compass released results of drilling completed at the Ouassada permit, along a 200-metre high-grade section of the Farabrakoura trend, known as the Creek zone. Reported intercepts include 6 metres of 65.6 grams gold per tonne starting at 20 metres and 13 metres of 9.25 grams gold starting at 21.1 metres.

The Creek zone is estimated to extend for 750 metres. Most of the drilling to date has been completed on the southern part of the Farabakoura target area.

Gold mineralization at Farabakoura has been traced over a strike of over 830 metres with additional parallel mineralized trends identified. Compass has outlined three potential resource target areas at Farabrakoura.

In August, the company identified three gold zones, up to 1 km long, over a 4.8 km distance at the Faraba-Coura permit, north of the Ouassada permit. Follow-up drilling is planned with a total of over 20 drill targets identified over the 15 km Farabrakoura trend.

A total of over 40 targets have been identified across the company’s holdings in Mali.

Compass plans to drill test additional targets at Farabrakoura and drill on other priority areas. Work is expected to start in January 2020.

In November, Compass announced a private placement with proceeds of about $5.5 million, with SEMAFO (TSX: SMF) subscribing for $2 million. SEMAFO is expected to own roughly 10% of the outstanding shares of Compass upon completion. Proceeds are expected to fund the exploration efforts in Mali through to the end of 2020.

Compass Gold has a market capitalization of $16.3 million.

Continental Gold (TSX: CNL) is building its high-grade Buritica gold mine in Colombia. The Buritica project covers 754 sq. km and is 65 km from the city of Medellin.

Mill facilities are expected to be mechanically complete in the first quarter of 2020. Ramp-up to commercial production is expected six to nine months later. The company has started pre-commissioning in a number of areas.

A 2016 feasibility study for the project outlines an underground operation with multiple ramp access starting at a 2,100 tonnes per day throughput and ramping up to 3,000 tonnes per day by the third year. Two high-grade zones were scheduled for initial mining.

Continental expects all-in sustaining costs (AISCs) at Buritica of about $600 per ounce. The company anticipates producing up to 300,000 oz. per year at the mine, with an updated mine plan for the first three years expected before commercial production starts.

Mineralization at Buritica is most extensive within the Yaragua and Veta Sur areas, with each system traced over about 1,300 metres of strike and over 1,800 vertical metres.

Resources at the project stand at 16.02 million tonnes in the measured and indicated categories at a grade of 10.32 grams gold and 40.8 grams silver for a total of 5.32 million oz. gold and 21 million oz. silver, with additional inferred resources of 21.87 million tonnes grading 8.56 grams gold and 37.3 grams silver for a total of 6.02 million oz. gold and 26.2 million oz. silver. Proven and probable reserves total 3.71 million oz. gold and 10.7 million oz. silver.

Buritica remains open for expansion on strike and at depth. In November, Continental announced that it has been granted an exploration license for the Electra South and Orion targets, within 5 km of the Buritica mine. At Electra South, high-grade veins have been traced over an area of 2,000 metres by 500 metres, whereas at Orion, high-grade mineralization has been identified over an area of 1,500 metres by 500 metres.

Between May 2017 and July 2019, Newmont-Goldcorp (TSX: NGT; NYSE: NEM) invested a total of US$109 million in Continental; it currently holds 19.9% of the company.Continental Gold has a $855-million market capitalization.
