CESAR lies along the copper-silver rich 200-kilometre-long Cesar Basin in northeastern Colombia. This region enjoys major infrastructure resulting from oil & gas and mining operations, including Cerrejon, the largest coal mine in Latin America, now held by global miner Glencore.
Max interprets the sediment-hosted stratabound copper-silver mineralization in the Cesar basin to be analogous to both the Central African Copper Belt (CACB) to the south and the Polish Kupferschiefer to the north. Almost 50% of the copper known to exist in sediment-hosted deposits is contained in the CACB, including Ivanhoe Mines Ltd (TSX: IVN) 95-billion-pound Kamoa-Kakula copper deposits in the Congo.
Kupferschiefer, the world’s largest silver producer and Europe’s largest copper source, is a mining orebody ranging from 0.5 to 5.5m thick at depths of 500m, grading 1.49% copper and 48.6 g/t silver. The silver yield is almost twice the production of the world’s second largest silver mine.
Due to the district-scale and copper-silver prospectivity of the Cesar Basin, Max has implemented a multi-faceted exploration program for 2021:
Advanced Drill Core Analysis and Modelling: ongoing interpretation of seismic sections and analysis of historical drill holes are all being integrated into our structural modelling of the Cesar Basin, in collaboration with Ingeniería Geológica Universidad Nacional de Colombia (“IGUN”) in Medellín (January 7, 2021 NR).
Geochemical and Mineralogical: research programs by the University of Science and Technology (“AGH”) of Krakow, Poland. AGH bring their extensive knowledge of KGHM’s world renowned Kupferschiefer sediment-hosted copper-silver deposits in Poland to the CESAR project.
Geophysical: Fathom Geophysics is interpreting seismic data, funded by the Company in collaboration with one of the world's leading copper producers.
Proprietary Field Exploration & Techniques: Max’s in-country exploration teams continue to target new copper-silver stratabound mineralized zones.
In 2020, Max discovered both the copper-silver rich AMS (previously named AM South) zone and the AMN (previously named AM North) zone 40-km north, collectively spanning over 45-km². Highlight values of 0.5 to 34.4% copper and 5 to 305 g/t silver range over outcrop intervals ranging 0.1 to 25.0m.
In March 2021, Max’s announced the CONEJO discovery, now spanning 3.2-km by 1.6-km and open in all directions. 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 (March 24, 2021 NR):
The 2021 URU discovery is located 30-km south of CONEJO, now expanded to 48-km² and open in all directions. URU appears to have major-scale potential; Thirteen rock samples over widths ranging from 10 to 25.0m returned values of 2.0% copper and above, thirty-seven returned values greater than 1.0% copper, with highlight values of 5.7 % copper and 37 g/t silver:
“The URU 48-km² zone remains open in all directions and potentially represents a zone of major proportions when compared to the world class Kupferschiefer and the Central African Belt deposits,” commented Max CEO, Brett Matich.
"In addition, MAX is conducting on-going exploration at the other four zones (CONEJO, SP, AMN, AMS, refer to Figure 3) within the CESAR North 80-kilometre-long-copper-silver belt of significant regional potential," he continued.
In addition, Max has initiated the process of mineral claim approvals and drill permitting.
CESAR West: Max has identified copper porphyry-style mineralization.
"The world’s transition to clean energy can only be accomplished with copper to build power grids, solar and wind farms, electric vehicles which typically require upwards of 180 pound of copper per vehicle. Copper's rapidly declining reserve base necessitates the need for new major discoveries of copper, positioning Max to take advantage of the copper shortfalls with the potential district size of the CESAR discoveries," he concluded.
