Project Overview

CESAR Copper-Silver in northeastern Colombia lies along the northern portion of the world’s largest producing copper belt (Andean belt). This region has oil & gas export operations and Glencore’s Cerrejón, the largest coal mine in South America and the basis for much of the critical infrastructure in the Cesar basin. Max is exploring a new basin-scale 90-kilometre-long copper-silver zone in Colombia, which Max succeeded in three significant high-grade copper-silver discovering from 2020 to 2021:

• Uru newly discovered in 2021, the Mining Concessions cover 70 km2. Identified over 15 kilometres, 10 metre widths, highlights of 14.8% copper and 132 g/t silver, 500 metre vertical elevations
• Conejo (40-kilometres north of Uru), newly discovered in 2021, currently 3.7-km long averaging 4.9% copper (2% cutoff)
• AM (70-kilometres north of Uru), newly discovered in 2020

Geology

Geologically, Max interprets the CESAR sediment-hosted copper-silver mineralization analogous to the Central African Copper Belt (CACB). Almost 50% of the copper known to exist in sediment-hosted deposits is contained within the CACB, including Ivanhoe Mines Ltd (TSX: IVN) 95-billion-pound Kamoa-Kakula discovery in the Demon Republic of Congo. The CESAR 90-kilometre-long target zone lies along a major structural corridor that connects the upper sediment-dominated part of the Cesar basin to the lower volcano-sedimentary portions.  These mineralized structures consist of faults and breccias that lie just below the sedimentary basin within a metavolcanic unit. Copper mineralization continues to be predominantly primary chalcocite with localized weathering to malachite and associated with silver credits similar to the mineralization characterized in the upper sedimentary horizons seen elsewhere in the Cesar basin.

The Uru zone lies along a major structural corridor that connects the upper sediment-dominated part of the Cesar basin to the lower volcano-sedimentary portions.  These mineralized structures consist of faults and breccias that lie just below the sedimentary basin within a metavolcanic unit, that have been identified over 15-kilometres in length, widths of 10 metres, the vertical relief ranges from 1,200m down to 410m.

Copper mineralization continues to be predominantly primary chalcocite with localized weathering to malachite and associated with silver credits similar to the mineralization characterized in the upper sedimentary horizons seen elsewhere in the Cesar basin.

Sits along a major structural corridor, analogous to the Central African Copper Belt, location of Ivanhoe Mines Ltd (TSX: IVN) 95-billion-pound Kamoa-Kakula discovery. Max identified 5 significant drilling targets over 15-km of strike, widths of 10 to 25-metres over 500m vertical, highlight values of 14.8% copper and 132 g/t silver:                             

• 14.8% copper and 132 g/t silver over 1.5m x 0.8m
• 5.6% copper and 87 g/t silver over 1.0m by 1.0m
• 4.3% copper and 8 g/t silver over 10.0m
• 3.9% copper and 7 g/t silver over 10.0m
• 3.6% copper and 12 g/t silver over 10.0m
• 3.0% copper and 6 g/t silver over 10.0m
• 3.0% copper and 37 g/t silver over 10.0m
• 2.7 copper and 10 g/t silver over 25m

Conejo Copper-Silver Discovery (March 2021)

Located 40-kilometres north of Uru,  the Conejo zone, currently 3.7-km long averaging 4.9% copper (using 2% copper cutoff). Conejo returned values greater than 5.0% copper from 23 rock panels varying from 5.0m by 5.0m to 1.0m by 1.0m. In addition, 66 rock panel samples returned values over 1.0% copper:

• 12.5% copper + 84 g/t silver over 5.0m by 5.0m
• 10.5% copper + 50 g/t silver over 3.0m by 2.0 m
• 10.4% copper + 95 g/t silver over 5.0m by 5.0m
• 10.2% copper + 62 g/t silver over 5.0m by 5.0m
• 10.0% copper + 80 g/t silver over 5.0m by 5.0m
• 8.7% copper + 89 g/t silver over 5.0m by 5.0m
• 8.4% copper + 60 g/t silver over 5.0m by 5.0m 
• 7.9% copper + 21 g/t silver over 5.0m by 5.0m 
• 7.7% copper + 84 g/t silver over 5.0m by 5.0m 
• 7.4% copper + 47 g/t silver over 5.0m by 5.0m
