VANCOUVER, British Columbia, June 08, 2021 (GLOBE NEWSWIRE) — Calibre Mining Corp. (TSX: CXB; OTCQX: CXBMF) (the “Firm” or “Calibre”) is happy to offer an replace on the Firm’s 80,000 metre, 2021 drilling program, highlighting outcomes of exploration and useful resource enlargement drilling on the Firm’s Libertad concessions.


Volcán Vein

  • 11.37 g/t Au over 5.4 metres ETW (“Estimated True Width”) from 61.4 metres (VN-21-026)
  • 9.26 g/t Au over 1.7 metres ETW from 76.9 metres (VN-21-030A)
  • 2.37 g/t Au over 6.2 metres ETW from 67.2 metres (VN-21-032)

Tranca Vein

  • 16.78 g/t Au over 2.8 metres ETW from 41.9 metres (TR-21-039)
  • 13.83 g/t Au over 4.4 metres ETW from 127.7 metres (TR-21-052)
  • 3.27 g/t Au over 4.1 metres ETW from 107.1 metres (TR-21-031)

2021 Calibre Drill Program

  • 16 drill rigs at present energetic on Calibre’s 100% owned properties
  • Calibre is guiding 170,000 – 180,000 ounces of gold manufacturing for the yr, producing sturdy money flows to self-fund new development alternatives and an intensive 80,000 metre exploration and infill drilling program

Darren Corridor, President & Chief Government Officer of Calibre, acknowledged: “We’re excited to see some new high-grade zones rising at Libertad. The district has produced over 1.9 million ounces of gold and we proceed to determine alternatives for extra ore sources near the Libertad mill. We’re very inspired by the preliminary outcomes of our first go drilling marketing campaign alongside the Volcán pattern the place we’ve confirmed the presence of high-grade gold mineralization in at the least two zones alongside a 1.5 kilometre vein system that up to now stays largely unexplored.”

“Drilling at Tranca continues to delineate a zone of close to floor gold mineralization with good potential for an open pit mineral useful resource. At Rosario, step-out drilling is testing the potential to increase the present gold useful resource one other 200 metres alongside strike to the southwest. At present three rigs are working at Libertad plus one on the Amalia satellite tv for pc concession situated 35 kilometres away.”

“Along with the drilling packages at our 100% owned properties, our associate Rio Tinto just lately commenced its 2021 exploration drilling marketing campaign focusing on giant porphyry model copper + gold targets, a part of the Borosi three way partnership venture through which Calibre is the present operator. At present we have now one drill working at Borosi and plan so as to add a second drill throughout the coming weeks.”

Exploration Drilling

The Volcán vein system is situated roughly 4 kilometres south of the Libertad mill. Earlier exploration drilling accomplished in 2012 and 2017 testing the higher 100 metres in two areas alongside the system returned a number of high-grade intercepts together with 9.69 g/t Au over 10.7 metres ETW from 49 metres in gap VN-17-009; 10.56 g/t Au over 4.5 metres ETW from 41.2 meters in holes VN-17-013; and 5.78 g/t Au over 4.1 metres from 111.2 metres in gap VN-17-021 (historic drill outcomes are supplied within the hooked up tables). Preliminary outcomes acquired from this yr’s drilling program have confirmed the presence of close to floor gold mineralization alongside the Volcán pattern which stays open alongside strike and at depth. The Firm plans to proceed drilling at Volcán with a second marketing campaign of step-out exploration holes drilled alongside strike to check the continuity of mineralization between the 2 zones and the potential for high-grade mineralization to increase at depth.

The Tranca vein system is situated roughly 9 kilometres east of the Libertad mill and 500 metres south of the Jabali underground mine at present in operation. Since early 2020, Calibre has been drilling alongside a 1.5 kilometre part of the Tranca pattern which has been traced for an additional 2.5 kilometres alongside strike to the east. Alongside strike to the west, the Tranca system extends into the Nancite prospect the place a number of veins happen. The Firm continues to be inspired by the continuity of gold grades and potential for greater grade shoots alongside the zone and plans to speed up exploration drilling with a second drill in the course of the coming weeks.

Useful resource Enlargement Drilling

Rosario Vein:

  • 3.67 g/t Au over 8.0 metres ETW from 99.1 metres (RS-21-070)
  • 2.34 g/t Au over 7.3 metres ETW from 130.8 metres (RS-21-069)
  • 3.13 g/t Au over 4.0 metres ETW from 112.8 metres (RS-21-084)
  • 4.02 g/t Au over 2.4 metres ETW from 69.8 metres (RS-21-085)

Jabali Vein:

  • 5.45 g/t Au over 3.3 metres ETW from 30.4 metres (JB-21-536)
  • 51.90 g/t Au over 0.8 metres ETW from 44.6 metres (JB-21-537)

Whereas we have now centered largely on exploration drilling this yr, we’re likewise happy with the outcomes of useful resource enlargement and infill drilling on the Rosario deposit the place we proceed to see alternatives to develop open pit mineral assets situated inside a brief trucking distance of the Libertad mill. At Jabalí, outcomes of a closing infill drilling marketing campaign will probably be built-in into the mineral useful resource estimate in help of future underground mine planning.

At Pavon, Calibre accomplished condemnation drilling and continues to discover alongside strike and down plunge of the Pavon Central and Norte veins together with on the just lately recognized Candida vein splay extending from the principle Pavon Norte deposit. At present, the Firm has two rigs working at Pavon and can proceed step out exploration drilling alongside strike and down dip of the principal vein programs.
