Calibre Mining (CXB-V) samples 52.3 m of 7.1 g/t Au at Montes de Oro

Aug 15, 2013 - News Release

Calibre Mining Corp. is providing an update on activities at the 100-per-cent-owned Montes de Oro target within the Siuna district, Borosi concessions, northeast Nicaragua. Highlights

  • Results from extensions of trench MTR13-009 have expanded the high-grade mineralized intercept to 52.3 metres grading 7.1 grams per tonne gold.
  • Additional high-grade trench results returned from recent work include: 23.0 m grading 5.25 g/t Au (MTR13-017), including 9.0 m grading 10.15 g/t Au, and 16.2 m grading 4.68 g/t Au (MTR13-019) including 6.0 m grading 10.14 g/t Au.
  • At Montes de Oro, trenching has partially tested a strong coincident gold-silver-copper-lead-zinc soil anomaly extending over a 400-metre-by-650-metre area that remains open to the northeast.


President and chief executive officer Greg Smith stated: "Calibre continues to advance the Montes de Oro target, intersecting high-grade gold mineralization over expanding widths. This high-priority target continues to return consistently high-grade gold intercepts with recent work now showing apparent widths of several 10s of metres. Ongoing work is advancing the understanding of the mineralization."

See tables at web site: http://www.calibremining.com

Based on the latest assays results at least two high-grade subparallel mineralized trends are present at Montes de Oro (MTR13-009 trend and MTR13-017 trend). The zones have an inferred northeast orientation and appear to dip shallowly to the northwest. The MTR13-009 trend may continue as far as MTR13-018, a distance of approximately 200 metres.

Six new trenches and three trench extensions were completed at Montes de Oro during July, 2013, for a total of 208.4 metres. The MTR13-017 tunnel extension returned a composite of 23.0 m grading 5.25 g/t Au and remains open to the northwest. The gold mineralization in MTR13-017 is distributed throughout the tunnel, primarily associated with a strongly oxidized horizon, which dips between 20 and 40 degrees to the northwest roughly concordant with bedding. The mineralized oxide zone present in MTR13R-024 is very similar to the zone present in MTR13-017 and may be an updip extension of the horizon located along strike to the west-southwest. MTR13-024 returned 3.70 m grading 3.86 g/t Au.

Other significant results are from trenches MTR13-022 with 6.0 m grading 4.73 g/t Au, and MTR13-025 with 3.5 m grading 5.51 g/t Au, 0.11 per cent copper and 0.32 per cent zinc. Both MTR13-022 and MTR13-025 contained lenses of massive sulphide with mineralization similar to MTR13-009. The mineralization present in trenches MTR13R-007, MTR13-018 and MTR13R-020 is similar in style, and is primarily hosted within a strongly oxidized, argillic altered and fractured equigranular diorite unit. No obvious quartz veining has been observed, but the rock is strongly fractured and contains rafts of sulphide-bearing sediments. A northeast-oriented zone of higher-grade mineralization can be traced over a length of 50 m between trenches MTR13-020 and MTR13-018. Lower-grade disseminated-style mineralization also exists with long intervals including 39.40 m grading 0.96 g/t Au in MTR13-018 and 50 m grading 0.53 g/t Au in MTR13-020.

In addition to the regional host volcano-sedimentary package, at least two phases of intrusive rocks have been mapped on the property: the principal hornblende-bearing equigranular diorite and a coarse hornblende diorite unit.

The existing soil anomaly at Montes de Oro is a strong coincident gold-silver-copper-lead-zinc anomaly, which extends over a 400-metre-by-650-metre area and remains open to the northeast. Two additional soil lines were added to the Montes de Oro soil grid to test the northeast extension, and a total of 22 samples were collected. The results are pending.

Work continues at Montes de Oro, targeted at further defining the high-grade gold mineralization, and testing the extensions of existing trenches and additional anomalous areas. Updated maps detailing the result of the current exploration programs will be posted on the company's website.

Quality assurance and quality control procedures include the systematic insertion of blanks, standards and duplicates into the rock sample strings. Samples are placed in sealed bags and shipped directly to Acme Labs in Managua, Nicaragua, for sample preparation, and then to Acme Labs in Vancouver, Canada, for gold fire assay and ICP (inductively coupled plasma) multielement analyses. The technical content in this news release was read and approved by Gregory Smith, PGeo, President and CEO of the company, who is the qualified person as defined by National Instrument 43-101.

Calibre Mining (CXB-V) and Iamgold (IMG-T) July 14, '14 have started the 2014 diamond drilling program on the Eastern Borosi gold-silver project, Nicaragua.

Calibre and Iamgold entered into an option agreement dated May 26, 2014, whereby Iamgold can earn a 51-per-cent interest in the Eastern Borosi gold-silver project consisting of 176 square kilometres within the Borosi concessions, northeast Nicaragua, by incurring $5-million (U.S.) in exploration expenditures and making $450,000 (U.S.) in payments to Calibre over three years. The total potential investment by Iamgold to earn a 70-per-cent interest in the Eastern Borosi project is $10.9-million (U.S.). The Eastern Borosi project hosts gold-silver resources in two deposits and a series of well-defined low-sulphidation epithermal gold-silver targets.

Highlights

  • Drilling equipment has been mobilized and drilling has commenced on the 3,400-metre 2014 drill program.
  • The 2014 drilling program will comprise an estimated 31 diamond drill holes designed to test approximately three kilometres of strike length of previously identified gold-silver-bearing structures.
  • Drilling will test a number of high-priority gold-silver targets, including Guapinol, Riscos de Oro extension, Blag, California, Veta Vancouver and Veta Toronto.
  • The current drilling program utilizing one drill rig is expected to take three months to be completed.


President and chief executive officer Greg Smith stated: "We are excited to start the drilling program on the Eastern Borosi project. The series of high-quality drill targets represent more than three kilometres of potential gold-silver-bearing structures within the tens of kilometres of potential structures which have been identified within this prolific district."

Drilling has begun on the Guapinol gold-silver target which has been prioritized based on previous exploration, including surface mapping, historic underground development and previous shallow drilling, soil and rock geochemistry, and LIDAR surveying. At Guapinol, results from surface channel sampling completed by Calibre include 1.3 metres at 21.0 grams per tonne gold and 13.3 g/t silver, and 0.9 metre at 9.6 g/t Au and 108.0 g/t Ag.

The Eastern Borosi project includes the Riscos de Oro and La Luna National Instrument 43-101 inferred mineral resources which total 4.70 million tonnes grading 2.31 g/t Au and 34.99 g/t Ag, containing 350,000 ounces of gold and 5.29 million ounces of silver. Both zones are open for potential expansion (see Calibre news release dated May 27, 2014, for details).

Updated maps detailing the planned drilling program at the Eastern Borosi project will be posted on the company's website.

Quality assurance and quality control procedures include the systematic insertion of blanks, standards and duplicates into the sample strings. Samples are placed in sealed bags and shipped directly to Acme Labs in Managua, Nicaragua, for sample preparation and then to Acme Labs in Vancouver, Canada, for gold fire assay and ICP-MS multielement analyses.
