Altiplano Discovers New Vein System at Maria Luisa; samples 2.50 Metres of 1.44 g/t Gold and 4.65% Copper

Altiplano Discovers New Vein System at Maria Luisa; samples 2.50 Metres of 1.44 g/t Gold and 4.65% Copper

Altiplano Metals Inc. (TSXV: APN) (WKN: A2JNFG) ("Altiplano" or the "Company") is pleased to announce progress of the decline advance and underground channel sampling of a newly discovered vein system intersected within the Maria Luisa decline (Table 1). The decline is currently being advanced parallel to projected gold-copper vein mineralization in a southeast direction towards historical underground workings in the southernmost portion of the property (Figure 1). The Maria Luisa project is located within the Atacama Region 100 km north of La Serena in Incahuasi, Chile.

Highlights

  • The Maria Luisa decline has advanced a total of 115 metres and has begun the crosscut to the main vein system expected to be intersected in approximately 15 metres.*
  • A new near surface high grade copper oxide vein system trending in a N-S orientation with mineable widths was intersected underground during the decline advance.
  • Underground mapping tested with channel samples ML_L004 and ML_L005 on this vein produced strong results, including 2.50 metres of 1.44 g/t Au and 4.65% Cu and 2.52 metres of 1.17 g/t Au and 0.93% Cu, respectively.
  • The newly discovered vein appears to be N-S orientated and will be tested in the second phase of the upcoming drill program. Vein sets in this orientation have been poorly understood and not mined historically but appear to have significant upside.
  • Geological mapping and drill planning is underway to fully evaluate this new trend of mineralization and its potential to add additional mineralized tonnage for extraction.
  • A seventy-tonne bulk sample from this vein system has been shipped to a third-party processor for recovery of the copper and gold.

President and CEO Alastair McIntyre comments: We are pleased with the underground progress at Maria Luisa where we will soon reach the first access point of the targeted main vein system. We are also excited to discover a new, highly mineralized, copper-gold vein system that has yielded very significant assays in early results. The presence and grade of this vein system supports the significant upside potential of multiple vein systems at Maria Luisa which remain largely unexplored."
