Calibre Mining and Centerra Continue to Advance the Siuna Project and Receive Positive Metallurgical Results From Cerro Aeropuerto
(firmenpresse) - VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 07/22/16 -- Calibre Mining Corp. (TSX VENTURE: CXB) (the "Company" or "Calibre") is pleased announce the Company and Centerra Gold Inc. ("Centerra") continue to advance the Siuna Project, which includes the La Luz targets and the Northern Siuna area, located in Northeast Nicaragua. Centerra can earn a 70% interest in the 253 km2 Project area by investing a total of $9.0 million in exploration on the property before December 31, 2020.
Highlights
President and CEO, Greg Smith stated: "the Calibre / Centerra partnership continues to advance the Siuna Project. Recent exploration has defined a series of drill targets along the Cerro Coyol - Tiburon Gold Trend and west of Cerro Aeropuerto. The positive results received for the metallurgical testing on the Cerro Aeropuerto drill core are encouraging. Field crews are busy further defining and prioritizing a series of kilometre-scale gold targets previously identified in the northern Siuna area."
A total of five bottle rolls were completed on material from drill core from the 2015/2016 diamond drilling program at Cerro Aeropuerto. Four samples were prepared of average grade (2.7 to 3.3 g/t Au) and one sample included the higher grade material averaging 146.4 g/t Au. All five samples have excellent recoveries at both 24 and 48 hours. Recoveries in all cases increased after 48 hour compared to 24 hours.
Table 1 - Cerro Aeropuerto Bottle Roll Leach Tests(1)
The average recovery of the four average grade samples is 95.6% after 24 hours and increased to 96.4% after 48 hours.
The higher grade sample returned 85% after 24 hours and 88 % after 48 hours. This sample includes material from an interval where thin section and SEM analyses has identified free gold and additional tests to evaluate the potential for gravity gold recovery is warranted.
On the Siuna Project in addition to the historic trend highlighted by the La Luz Deposit (past production of 2.3 million ounces gold) and the Cerro Aeropuerto resource (707,000 ounces gold and 3.1 million ounces silver) the results from the Project-wide La Luz soil grid also defined a second gold anomalous trend, the Cerro Coyol - El Tiburon Trend. Within the Northern Siuna area existing gold anomalies include; Montes de Oro, Mina Victoria, Cerro Aza, Roskilete, and others. The current exploration and fieldwork is concentrated on a trenching program targeting geological, geochemical, and geophysical anomalies generated by the work to date. The results of the trenching program will be used to prioritize drill targets which will be tested by an additional 1,600-1,800 metres of diamond drilling to be completed in 2016. Further work, consisting of in-fill soil sampling, rock sampling and trenching, will be completed on high priority targets with the Northern Siuna area.
The La Luz Project is located in the south-west portion of the Borosi Concessions and contains the past producing open pit and underground La Luz Mine that produced 17.1 million tonnes of ore grading 4.14 g/t gold (2.3 million ozs gold) as well as, one kilometre to the south, the NI43-101 compliant Inferred Resource at the Cerro Aeropuerto gold-silver deposit which hosts 707,750 ozs gold and 3.1 million ozs silver in 6.05M tonnes grading 3.64 g/t Au and 16.16 g/t Ag at a cut off of 0.6 g/t ().
