High-Grade Gold Deposit in an Emerging Polymetallic District
This MacDonald Mines Exploration Ltd. profile is part of a paid investor education campaign.*
MacDonald Mines Exploration Ltd. (TSXV:BMK) is a mineral exploration company focused on gold exploration in Canada. The company retains 100 percent ownership of the 17,720-hectare SPJ project near the mining-friendly jurisdiction of Sudbury, Ontario. The property is accessible year-round and is close to key infrastructure such as rail, road, power and a skilled workforce.
The SPJ project hosts the past-producing Scadding mine, which reportedly produced 914 kg of gold from 144,000 tons of mineralized material grading 7.43 g/t gold during the 1990s. MacDonald Mines believes that it can bring the mine back into production quickly. Doing this should allow the company to capitalize on rising gold prices.
In the meantime, MacDonald Mines has confirmed the presence of iron oxide-copper-gold (IOCG) style mineralization at the Scadding deposit. IOCG deposits are some of the largest deposits on the planet. MacDonald Mines Chief Geologist Jean-Francois Montreuil is leading the company towards understanding the type of structures that control mineralization on the property, and is currently building a predictive model for targeted exploration on the SPJ Project.
Through Montreuil’s guidance, MacDonald Mines has identified several areas on the property that are rich in gold and other elements, which is indicative of an IOCG deposit. Highlights from this area include 6.14 meters grading 11.10 g/t gold and 1.8 meters grading 3.29 g/t gold.
These results were incorporated into a 2019 NI 43-101 technical report, which suggests a two-phased exploration plan for MacDonald Mines moving forward. Phase One is focused on understanding the attributes of the Scadding deposit’s high-grade gold mineralization, and Phase Two is expected to focus on expanding the mineralization at the deposit.
Phase One was completed this Fall and Phase Two exploration is currently underway at the SPJ project. These high-grade gold results have captured the attention of Eric Sprott, who has invested C$1.5 million into the company. The financing is expected to go towards exploring and developing the Scadding deposit

SPJ IOCG Project
The wholly-owned 17,720-hectare SPJ project is located 33 kilometers southeast of Sudbury, Ontario. The property is close to key infrastructure such as rail, road, power, a skilled workforce and resides in a mining-friendly jurisdiction. The property is also accessible year-round.
The SPJ project hosts the past-producing Scadding mine, which reportedly produced 914 kg of gold from 144,000 tons of mineralized material grading 7.43 g/t gold during the 1990s. The property is also located within 500 meters of the historical Norstar mine, which reportedly produced 63,000 tons of ore grading 7.2 g/t gold and 0.9 percent copper. Grab samples from the Norstar waste pile have also returned values between 0.065 percent to 0.3 percent cobalt.
Due to the past-producing nature of the Scadding mine, MacDonald Mines has an opportunity to push the Scadding mine back into production quickly.
MacDonald Mines believes that the property has the potential to host an IOCG-style deposit. IOCG deposits are some of the largest deposits on the planet and can vary in their metal content. IOCG orebodies are usually found in Archean to Proterozoic-aged terrains throughout the world, often in crustal-scale fault zones.
The world’s largest IOCG deposit is BHP Billiton’s (ASX:BHP,NYSE:BHP,LSE:BLT) Olympic Dam deposit in Australia. Other notable IOCG deposits include Lundin Mining’s (TSX:LUN) Candelaria deposit in Chile, Wheaton Precious Metals Corp.’s (TSX:WPM,NYSE:WPM) Salobo deposit in Brazil and Vale’s (NYSE:VALE) Sossego deposit in Brazil.
As part of the company’s fall 2019 exploration program, MacDonald Mines completed grab sampling on the property within and outside of the Scadding mine area. The results were rich in gold and contained other elements, which are indicative of an IOCG deposit. Grab samples collected on the property returned anomalous cobalt, copper and nickel. A uranium anomaly in the host-rock, a typical indicator of IOCG deposits, was also identified on the property. Three uranium anomaly trends that extend over a trike length of up to 9 km illustrate the size potential.
MacDonald Mines’ focus for 2019 was to confirm and expand on known high-grade gold zones that comprise the Scadding deposit. To this aim, the company launched a 2,000-meters drilling program at the Scadding deposit that was quickly expanded to 10,000 meters.
A 2019 NI 43-101 technical report was filed in October 2019. The report outlined a two-phased exploration program to demonstrate that a sizeable deposit on the SPJ project. Phase One is focused on understanding the attributes of the Scadding deposit’s high-grade gold mineralization, and Phase Two is expected to focus on expanding the mineralization at the deposit.
As part of Phase One exploration, MacDonald Mines drilled the Scadding deposit, near the Scadding Mine, to explore the high-grade gold zones to the south, east and west of the deposit along with newly discovered zones. The company also expanded its prospecting and trenching programs to include the areas surrounding the Scadding deposit.
MacDonald Mines expanded its initial 2,000 m drilling program at the Scadding Depsoit to 10,000 meters on Oct. 19, 2019. Results from the first 5 holes reported indicate that several N-S gold-bearing structures are present on the property. To date, the Company has traced mineralization over a width of 500 meters and a length of 650 meters at the Scadding deposit. The Company will undertake geophysical surveys in November 2019 and early 2020 to help pinpoint future drill targets.
Results from reported drill holes include:
- SM-19-001: 52.02 g/t gold over 12.3 meters, 5.73 g/t gold over 5.5 meters and 11.12 g/t gold over 7.3 meters.
- SM-19-002: 14.04 g/t gold over 4.21 meters, 3.21 over 15.29 meters
- SM-19-003: 11.1 g/t gold over 6.14 meters including 23.32 g/t gold over 1.58 meters and 3.29 g/t gold over 1.8 meters
- SM-19-004: 5.15 g/t gold over 3.0 meters, 3.03 g/t gold over 1.37 meters and 9.02 g/t gold over 1.98 meters including 20.38 g/t gold over 0.84 meters.
- SM-19-005: 7.75 g/t gold over 1.44 meters, 21.66 g/t gold over 1.64 meters including 40.6 g/t gold over 0.87 meters and 8.1 g/t gold over 1.9 meters.
