The wholly-owned CESAR project in north east Colombia lies along a 100-kilometre sediment-hosted copper-silver belt, that resembles Kupferschiefer in Poland. The CESAR region has major infrastructure. Mining operations include Cerrejon, the largest coal mine in Latin America, jointly owned by global miners BHP Billiton, XStrata and Anglo American.
For the past eight months, Max's geological teams have been identifying copper and silver mineralization within a 40-kilometre by 10-kilometre target area. In-country field teams are conducting mapping and rock chip sampling to identify mineralized structures along the strike length to determine the continuity, thickness, and potential target size.
The new CESAR discoveries consist of AM SOUTH, which features 4 kilometre by 4 kilometre zone of stratabound copper-silver mineralization open in all directions. Earlier this year, sampling from 0.1 to 25-meter intervals returned highlight values of 5.4% copper and 63 g/t silver.
The second is AM NORTH, located 40-kilometres NNE along the same mineralized trend as AM SOUTH. The AM NORTH zone is significant, extending in excess of 11-kms, with a high-grade component values of 24.8% copper + 230 g/t silver over continuous 4-metre by 1-metre outcrop and 1.8-kilometres east 10.4% copper + 88 g/t silver over 1-metre outcrop (refer news release June 23, 2020).
In addition, two subsequent bulk samples 10.4% copper + 88g/t silver and 3.5 % copper + 29 g/t silver, remembering the target is Kupferschiefer style tonnage and grades. KGHM’s Kupferschiefer is Europe’s largest copper mine, in 2018 producing 30 million tons of ore grading 1.49% copper and 48.6 g/t silver from a mineralized zone that averages 0.4 to 5.5-metre thickness. In addition, it is the world’s leading silver producer, providing 40 million ounces in 2019, almost twice the production of the world’s second largest silver mine, according to the World Silver Survey 2020.
Max is looking at CESAR from the big picture, with assistance from the Colombia National University, Poland’s University of Science and Technology (“AGH”), and a major copper company, which is working with Fathom Geophysics in completing technical studies. The aim of Fathom’s study is to map stratigraphic (rock layers) features and alteration signatures that can help to pinpoint stratabound copper-silver mineral horizons at CESAR. The collaboration with the major copper producer and the study being carried out by Fathom complements a research program initiated with AGH of Krakow, Poland. AGH have a long history of cooperation with KGHM, owner of Kupferschiefer, the largest copper producer in Europe and the world’s largest silver producer. (refer news release May 13, 2020).
