Pico Quemado Coal 

 

Location: Rio Negro, Argentina
1400km southwest of Buenos Aires

The Pico Quemado Coal Project is located in the western part of Rio Negro province. Dark Horse is earning an interest in the properties held by joint venture partner Trendix SA. 

The Pico Quemado Coal Project is a high priority prospect for Dark Horse and includes a number of highlights: 

  • Tertiary synclinal Nirihuau Basin - southern Pico Quemado and northern Chenquenyieu
  • 4 main seams with 10m aggregate coal thickness dipping 10-30 degrees, 22km strike length
  • Drilling and small scale mining in WWII era

Coal analyses from Pico Quemado (announced to the ASX August 26, 2015) show the Pico Quemado coal is high volatile bituminous with good thermal, and potential metallurgical, properties with general quality ranges as follows: 

  • Moisture: 2 - 5%
  • Ash: 15 - 30% 
  • Volatiles: 24 - 33% 
  • Calorific value: 5000 - 7000 Kcals/kg  
  • Sulphur: 0.2 - 0.6% 
  • Crucible swelling index: up to 5 
  • Mean maximum reflectance: 0.56 - 0.68% 

Exploration 

The first phase drilling program was completed during April and May 2017, following a geological mapping phase carried out between December 2016 and March 2017. 

A total of 2,408 full cored metres was successfully drilled, 15 holes and 1,837m at Pico Quemado and 8 holes and 572m at Chenqueniyen. The drilling confirmed the stratigraphic sequence and seam thickness, matching the historic drillhole data of the 1950's, and confirming its authenticity. 

Pico Quemado has an upper seam sequence and a lower seam sequence, separated by between 80 to 90 metres of sandstones and siltstones. The upper seam sequence has a thickness ranging up to 4m and the lower seams up to 7.5m in thickness.
