MAX RESOURCE CORP.  reports high-grade copper and silver results over 1.6-km by 0.6-km zone from the new CONEJO discovery at CESAR North, within the wholly-owned CESAR copper-silver project in NE Colombia.

Highlight assays greater than 9% copper and 50 g/t silver:

  • 12.5% copper + 83.5 g/t silver over 5-metre by 5-metre (878335)
  • 10.7% copper + 51.6 g/t silver over 1-metre by 1-metre (878389)
  • 10.5% copper + 50.1 g/t silver over 3-metre by 2-metre (878603)
  • 10.4% copper + 95 g/t silver over 5-metre by 5-metre (878338)
  • 10.2% copper + 62 g/t silver over 5-metre by 5-metre (878334)
  • 10.0% copper + 80 g/t silver over 5-metre by 5-metre (878363)
  • 9.5% copper + 120 g/t silver over 1-metre by 1-metre (878390)

Twenty-two rock panel samples returned high-grade values above 5% copper from panels varying from 5m by 5m to 1m by 1m. Overall, sixty-six rock panel samples returned significant values over 1% copper and they are presented in Table 1. Max cautions investors that rock panel sampling can be selective and are not necessarily representative of the mineralization.

The new CONEJO copper-silver discovery was delineated over a zone of 1.6-km by 0.6-km, open in all directions, and hosted in a stockwork cross cutting igneous host rock, overlying or cross cutting mineralized stratabound horizon.

The Max field team is mapping the rock bearing mineralization to determine the potential volume and average copper-silver grades of the CONEJO zone.

“CONEJO is a new high-grade copper-silver discovery, extending the CESAR North outcropping discoveries to over 35 kilometres of combined strike length. The overall scale of the zone appears to be of district proportions,” commented Max CEO, Brett Matich.

“CONEJO continues the pattern of new copper-silver outcrop discoveries as the Company’s in-country team extends exploration activities further into unexplored areas of Max’s CESAR Project,” he concluded.

Max interprets the stratabound copper-silver (SEDEX) mineralization in the CESAR Basin to be analogous to the Kupferschiefer Basin in Poland. The Kupferschiefer deposits, Europe’s largest copper source, produced 3MT of copper in 2018 and 40 million ounces of silver in 2019 from an orebody 0.5 to 5.5-metres thick, grading 1.49% copper and 48.6 g/t silver. This silver yield is almost twice the production of the world’s second largest silver mine.

The CESAR project in North Eastern Colombia covers a significant portion of the 200-km long CESAR basin, has now been demonstrated to contain widespread highly prospective copper-silver mineralization.,

This region enjoys major infrastructure as a result of oil & gas and mining operations, including Cerrejon, the largest coal mine in Latin America, jointly owned by global miners BHP Billiton, Xstrata and Anglo American (refer to Figure 2).

Due to the regional-scale copper-silver prospectively of the CESAR basin, Max has initiated a multiple faceted exploration program for 2021:

Advanced Drill Core Analysis and Modelling: ongoing interpretation of seismic sections and analysis of historical drill holes, 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);

Geochemical and Mineralogical: geochemical and mineralogy 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;

Geophysics: Fathom Geophysics is interpreting regional airborne magnetic and radiometric data, funded by the Company in collaboration with one of the world’s leading copper producers;

Proprietary Field Exploration & Techniques: Max exploration teams continue to expand its copper-silver outcrop discoveries;

  • CESAR North:
    • In 2020, Max identified stratabound copper-silver mineralization (SEDEX) spanning over 45 sq. km, with highlight values of 0.1 to 34.4% copper and 5 to 305 g/t silver over continuous intervals ranging 0.1 to 25.0-metres; The Max team is exploring this 40-km long belt;
    • In 2021,Max discovered fracture-controlled copper mineralization hosted in igneous host over 1.6-km by 0.6-km (CONEJO zone), open in all directions, that lies along the CESAR North Kupferschiefer-type (SEDEX) copper-silver mineralization;
  • CESAR West: Max has initiated sampling and mapping the continuous 180-kilometre-long landholding with already discovered copper-silver mineralization;
  • CESAR South: Recent 15-km discovery zone, highlight grab sample values of 11.4% copper + 656g/t silver.
