100% Calibre owned Concessions
Calibre's 100% owned concessions contain the Cerro Aeropuerto, La Luna and Riscos de Oro Gold-Silver Deposits that host a combined NI43-101 Inferred Resource at a 0.6 g/t AuEq cut-off of 10,750,000 tonnes grading 3.06 g/t Au and 24.38 g/t Ag containing 1,057,000 oz Au, 8,430,000 oz Ag (see News Release Sept. 5, 2012 for details). On-going exploration programs by Calibre continue to advance the Eastern Epithermal Camp and the Western Siuna Camp.
The Eastern Epithermal Gold-Silver District is in the north-eastern portion of the Borosi Concessions and contains the Riscos de Oro and La Luna gold-silver deposits. Recent work has concentrated on the newly acquired Guapinol - La Sorpresa Trend consisting of a series of anomalous zones, past producing pits, shallow shafts and existing small scale mining areas extending over eight kilometres. Results of this work have defined a northeast- trending, highly anomalous zone between Guapinol and California outlining a series of up to seven sub-parallel, closely-spaced, structures which provide an excellent near surface target three kilometres long and averaging 500 metres wide.
Historic drilling at Guapinol consisted of 16 diamond drill holes testing a single structure along 150 metres of strike length and down to a depth of approximately 80 vertical metres. Highlights include: G-4; 1.84 m @ 2.33 g/t Au and 276.48 g/t Ag, G-6; 1.52 m @ 28.87 g/t Au and 21.87 g/t Ag, G-8; 3.10 m @ 13.08 g/t Au and 10.02 g/t Ag, and G-11; 0.5 m @ 32.43 g/t Au and 103.15 g/t Ag (see News Release Nov. 27, 2012 for further details).
The current exploration program consists of detailed soil sampling and trenching. Recent grab samples at Guapinol include surface quartz vein material grading; 13.1 g/t Au, 18.8 g/t Au and 3.8 g/t Au, while at California three kilometres NE sampling has returned; 3.2 g/t Au, 21.9 g/t Au, and 9.5 g/t Au. Recent grab sampling of vein material at La Sorpresa (8.5 kilometres NE of Guapinol) has returned consistently anomalous results including; B13R3072 @ 14.2 g/t Au and greater than 100 g/t Ag, B13R3071 @ 17.1 g/t Au and 74.0 g/t Ag, B13R3068 @ 9.9 g/t Au and 66.9 g/t Ag, and B13R3080 @ 0.99 g/t Au and 12.2 g/t Ag.
The Siuna District is in the western portion of the Borosi Concessions. Exploration completed by Calibre has identified porphyry and skarn targets. The Siuna District is host to the historic La Luz mine which produced more than 2.5 million ounces of gold from open pit and several underground levels developed down to 450 metres below surface. The District also hosts the existing Cerro Aeropuerto Inferred resource containing 700,000 ounces of gold and 3.1M ounces of silver (6.05Mt @ 3.64 g/t Au and 16.2 g/t Ag), and the Cerro Potosi target. Calibre's exploration programs have concentrated on the northern extension of the mineralized belt 10 to 40 kilometres north of the La Luz mine. The two main targets Montes de Oro and La Virgen are defined by strong gold-copper soil anomalies which have now been tested by trenching.
The La Virgen prospect was defined through a combination of prospecting, stream sediment sampling and subsequent soil sampling that defined a broad Au-Cu-As anomaly over a 500 m x 1000 m area. The most anomalous results have been traced to a 200 m x 300 m area near the peak of Cerro La Virgen where a series of narrow northeast oriented diorite dikes (dipping steeply towards the southeast) cut siltstone units from the Todos Santos Formation. In trench exposures, the dikes range from 1.20 - 17.80 metres in width, are often strongly oxidized containing highly anomalous Au-Cu values, and are commonly located in close proximity to steeply dipping faults and shears. Propylitic style alteration and minor quartz veins are noted in the surrounding wall rocks, which can also contain anomalous Au-Cu values. A large diorite body, located to the south of this area, is believed to be the source of the dikes. Significant trench results from this area include: 45.00 m @ 0.40 g/t Au and 0.19% Cu including 9.00 m @ 1.39 g/t Au and 0.19% Cu (VTR12-001), 7.50 m @ 0.21 g/t Au and 0.12% Cu (VTR13-011), 3.80 m @ 0.77 g/t Au and 0.72% Cu (VTR13-012), 3.90 m @ 1.55 g/t Au and 0.14% Cu (VTR13-013) and 10.20 m @ 0.70 g/t Au and 0.11% Cu (VTR13-021).
