Coastal Gold to Focus on Potential Development of Underground High Grade Mineral Resource at Hope Brook, Newfoundland

TORONTO, ONTARIO--(Marketwired - June 3, 2014) - COASTAL GOLD CORP. (TSX VENTURE:COD)(FRANKFURT:CY41) (the "Company") announces that after a detailed review of engineering options, the Company will focus on potential development of an underground higher grade mineral resource included within the previously released mineral resource estimate for the Company's Hope Brook Gold Project in Newfoundland (see press release dated December 4, 2013). This approach takes advantage of the existing ramp that extends to a depth of 350 metres below surface and allows ready access for the potential development of existing underground mineral resources. The high grade mineral resource has been defined using a 3.0 g Au/t cutoff for the underground resource and a US$900/oz constraining shell (cutoff grade equals 0.7g Au/t) for the potential open pittable resource as follows:

  • Mineral resource targeted for potential underground development of 2,284,000 tonnes grading 4.43 g Au/t containing 326,000 ounces gold in the indicated category and 769,000 tonnes at 4.23 g Au/t containing 105,000 ounces gold in the inferred category.
  • Potential open pittable high grade mineral resource of 8,682,000 tonnes grading 2.69 g Au/t containing 751,000 ounces gold in the indicated category.
  • Overall high grade indicated mineral resource of 10,966,000 tonnes at 3.05 g Au/t containing 1,076,000 ounces gold and inferred mineral resource of 812,000 tonnes grading 4.06 g Au/t containing 106,000 ounces gold.

Dr. Bill Pearson, P.Geo., President and CEO of Coastal Gold, commented: "The overall total high grade indicated resource contains only 13% less ounces than the original reported indicated resource attesting to the excellent continuity of the Hope Brook deposit at higher cutoff grades. Underground development would facilitate follow-up drilling on potential high grade target areas already identified from our previous surface drilling, including Hole HB-11-23 which intersected 11.4 g Au/t over a true width of 20.9 metres (see press release dated April 27, 2011).

Allan Polk, P.Eng, Project Manager for the Preliminary Economic Assessment (PEA) at Hope Brook commented: "Focusing on a conceptual plan for development of underground resources to take advantage of the existing ramp has the potential to enable production of more ounces from less tonnage in the earlier years of the conceptual mine, thus reducing overall capital costs. The underground high grade resource is very attractive for a moderate size, bulk mining operation as it is based on a minimum five metre wide block size and in many locations the thickness is much greater. If the underground mine is successfully established, the potential open pittable resources would be integrated later into the conceptual production plan. While more engineering work is required to complete a PEA, we believe that this conceptual plan will provide the most efficient approach for potential development of Hope Brook."

High Grade Mineral Resource Estimate

The revised conceptual production approach takes advantage of the existing ramp that extends to a depth of 350 metres below surface and allows early access for the potential development of existing underground mineral resources, with development of an open pit to follow. This new concept for the project also incorporates the promising results from recent pre-sorting testwork which indicates potential for rejection of the majority of the primarily barren mafic dyke material associated with the mineralized material, prior to conventional milling. The higher grade subset of the existing mineral resource, exclusive of the mafic dyke material, has been estimated within a US$900/oz constraining shell at a 0.7 g Au/t cutoff grade and the underground resource is at 3.0 g Au/t cutoff grade as presented in Table 1.

Notes

1. For further details see the independent technical report, entitled "2013 Mineral Resource Estimate, Technical Report Hope Brook Gold Project, Newfoundland and Labrador, Canada" (the "Technical Report"), dated January 17th, 2014, prepared for Coastal Gold by AGP Mining Consultants Inc. ("AGP") and Mercator Geological Services Limited. The Technical Report is available under the Company's profile on SEDAR at www.sedar.com and on the Company's website at www.coastalgold.ca.

2. The high grade mineral resource estimate has been defined using a constraining shell at $US900/oz gold price (cutoff grade of 0.7 g Au/t) and a an underground resource below the constraining shell at a cutoff grade of 3.0 g Au/t, as compared to the original estimate which used a $1400/oz constraining shell (0.5 g Au/t cutoff) and a 2.0 g Au/t cutoff for underground resource). This high grade mineral resource for Hope Brook is a subset of the mineral resource estimate released December 4, 2013 and in the Technical Report filed on SEDAR.

3. High grade resources are undiluted with mafic dykes removed. Positive sorting tests indicate that the primarily barren mafic dyke material can be effectively removed after initial crushing. Improvements in modeling in the last resource update have allowed the dyke material to be removed as dilution from the model for mineral resource reporting.
