Continental Gold: Neue weltklasse Gold-Proben von Multi-Millionen Goldunzen-Projekt Buriticá in Kolumbien

Der Top-Gold-Developer Continental Gold (TSX:CNL) erzielt weitere, signifikante Projekt-Fortschritte auf dem Flaggschiff-Asset (Buriticá) in Kolumbien. Die neuen Resultate könnten die ökonomischen Kennziffern und Parameter in der jüngsten PEA ordentlich verbessern:

Continental Gold Boosts Confidence in Proposed Mining Plan With Underground Sampling at Yaraguá System, Buriticá, Colombia

TORONTO, ONTARIO--(Marketwired - Jan. 7, 2015) - Continental Gold Limited (TSX:CNL)(OTCQX:CGOOF) ("Continental" or the "Company") is pleased to announce new channel sampling results from development drifts and cross-cuts in upper levels of the Yaraguá mine at the Company's 100%-owned Buriticá project in Antioquia, Colombia. Approximately 4,000 metres of total underground development accessing the Yaraguá system has been completed to-date, providing for detailed evaluation of the geometries and grades of precious metal distributions, mining conditions and metallurgical recoveries through the Yaraguá pilot plant. The Company recently released a Preliminary Economic Assessment, based partly on underground development, for the Buriticá project.
Highlights (referenced in Figures 1, 2 and 3 and Tables I and II)
  • Systematic channel sampling across drifts in the San Antonio Vein (Level 0 and Level 1) and the NWSE Vein (Level 0) has demonstrated continuity of high-grade gold mineralization through substantial strike lengths over true horizontal widths approximating those proposed for mining stopes. Results include:
    • 1.77 metres @ 50.1 g/t gold and 68 g/t silver along 61.5 metres (San Antonio Vein, elevation of 1,560 metres);
    • 1.74 metres @ 34.7 g/t gold and 63 g/t silver along 120.5 metres (San Antonio Vein, elevation of 1,496 metres); and
    • 1.24 metres @ 32.4 g/t gold and 112 g/t silver (NWSE Vein, elevation of 1,560 metres).
These results increase the confidence levels in mineral resource estimates for upper Yaraguá, demonstrating higher grades X thicknesses than in the current mineral resource estimate set out in the Company's technical report entitled "Buriticá Gold Project, NI 43-101 Technical Report Preliminary Economic Assessment, Antioquia, Colombia", dated December 22, 2014 with an effective date of November 17, 2014 (the "2014 PEA"). The 2014 PEA is preliminary in nature and includes inferred mineral resources that are considered to be too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the 2014 PEA will be realized. Further, mineral resources that are not mineral reserves do not have demonstrated economic viability.
  • Continuous channel sampling of cross-cuts and other drifts on Level 0 has shown widespread mineralization in the form of veins and veinlets oblique to and between the master veins in the current Yaraguá mineral resource envelope. Mineralized intervals, over true horizontal widths, include:
    • 15.8 metres @ 8.6 g/t gold and 19 g/t silver (including 2.2 metres @ 31 g/t gold and 50 g/t silver, HW Vein);
    • 17.5 metres @ 7.8 g/t gold and 19 g/t silver (including 2.24 metres @ 10.3 g/t gold and 30 g/t silver, HW Vein); and
    • 8.8 metres @ 5.4 g/t gold and 12 g/t silver (including 0.55 metres @ 28 g/t gold and 110 g/t silver, NWSE Vein).
  • These results may support the potential development of mine openings additional to and/or broader than those contemplated in the provisional mining plan in the 2014 PEA.
  • Mining dilution may also decrease with the incorporation of greater than the zero grades of gold and silver assumed in the 2014 PEA to be outside the hard boundaries of the modelled veins including in the Level 0 area. Further work is underway to determine whether mining dilution grades in future economic studies can be improved.
"The results of the ongoing underground sampling in the Yaraguá system complements the Company's recent bulk sampling of the Veta Sur system and continues to increase the confidence of mineralization between veins, which bodes well for improving dilution expectations," commented Ari Sussman, CEO..
