NCG Focusses on High Grade Subset of Three Bluffs Resource Estimate
10.07.2014 | Marketwire
EDMONTON, ALBERTA -- (Marketwired - Jul 10, 2014) - North Country Gold Corp. (TSX VENTURE:NCG) (OTCQX:NCGDF) ("North Country", "NCG" or the "Company") today announced the Company has completed a review of the existing combined open-pit/underground resource estimate for the Three Bluffs Gold Deposit published in April 2013 and is pleased to highlight a potential high-grade underground subset contained within the current estimate, which the Company considers to demonstrate the potential existence of a conceptual high-grade underground deposit at Three Bluffs. "From the results of our high-level trade off analysis and logistical studies announced January 22, 2014, and North Country's belief that the Three Bluffs Gold Project may be suited to a possible medium sized operation which focusses on coherent trends of high grade gold mineralization, this subset of the resource estimate clearly demonstrates the presence of considerable high grade components to the deposit", stated Brian Budd, President of North Country Gold. "Our ongoing work programs will continue to upgrade our geological knowledge of these structures as we pursue strategies to potentially grow the present high-grade resource base and advance the project towards preparation of a possible PEA" added Mr. Budd.
High-Grade Subset
Utilizing an overall block cut-off grade of 5.0 g/t, which the company believes better reflects underground mining costs at these deposits and at this location, a possible high-grade underground subset of the existing Three Bluffs resource estimate contains an indicated resource of 1.140 Mt grading 11.21 g/t Au for 411,000 ounces gold and an inferred resource of 1.900 Mt grading 9.15 g/t for 558,000 ounces gold.
Table 1 summarizes the current Three Bluffs resource estimate queried at a 5.0 g/t grade cut-off, which is a high-grade underground subset of the existing combined open pit and underground resource estimate previously released April 23, 2013 as summarized in Table 2 below.

Three Bluffs Gold Deposit
The Three Bluffs gold project is a structurally controlled lode gold system hosted within oxide facies iron formation and greywackes. The deposit currently hosts an open-pit/underground resource of 4.30 Mt at 4.91 g/t gold for 683,000 ounces gold (indicated) and 5.52Mt at 5.43 g/t gold for 965,000 ounces gold (inferred) using a cut-off grade of 1.35 g/t for open pit (inside Whittle shell) and a cut-off grade of 2.5 g/t for underground (outside Whittle shell) (See press release dated April 23, 2013, Table 2, and applicable notes).
To date, Three Bluffs has been drill tested along a strike length of 4.1 kilometres to depths of 500 metres below surface with gold mineralization persisting to depth where the company has identified additional mineral potential* comprising 4.5 to 7.5 million tonnes grading between 3.8 g/t and 7.3 g/t gold (see press release date April 23, 2013). *Estimates of the potential quantity and grade of additional mineral potential' at Three Bluffs are conceptual in nature as there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

*Notes (Applicable to Tables 1 and 2)
- A total of 17 domains utilized in grade estimation of the 0.50g/t wireframes and 16 domains for the 1.0 g/t wireframes, Au capping by domain from 75 g/t Au to 30 g/t Au
- Block grade estimation of 0.50 g/t and 1.00 g/t wireframes utilizing ID3 interpolation
- Block grade estimation for 0.50 g/t and 1.0 g/t wireframes performed by successive search ellipsoids with first pass of 15m x 15m x 5m, second pass 30m x 30m x 10m and third pass 75m x 75m x 20m
- Open pit resources (inside whittle) are estimated at a pit discard grade of 1.35 g/t Au with 93% Au recovery utilizing a long term gold price of US$1,500 per ounce, whittle pit shell on the 0.50g/t block model was utilized to constrain the open-pit resources
- Underground resources constrained from 1.0 g/t wireframe block model below the optimized Whittle pit using a 2.5 g/t block cut-off
- Numbers may not add-up due to rounding
- Prior resources for Three Bluffs were completed by Roscoe Postle Associates Ltd in April of 2012 (see press release dated April 4th, 2012 and the Technical Report on the Three Bluffs Project, Nunavut Territory, Canada filed on Sedar, May 18, 2012)
- Mineral resources, which are not mineral reserves, do not have demonstrated economic viability
- The quantity and grade of reported Inferred resources are uncertain in nature and there has been insufficient exploration to classify these Inferred resources as Indicated or Measured, and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured category
- There are no known legal, political, environmental, or other risks that could materially affect the potential development of the mineral resources
- *Underground high grade subset constrained by applying strict 5.0 g/t block cut-off to the existing 1.0 g/t wireframe block grade estimation. This subset is not in addition to the current open pit and underground indicated and inferred resource but rather is that portion of the 1.0 g/t Au mode resource that reports to the higher block grade cut-offs.
- The information contained in this announcement is not intended to change the existing resource estimate for Three Bluffs as previously announced by the Company on April 23, 2013.
Resource Methodology
The 2013 Three Bluffs Resource estimate has been prepared by Dave Rennie, P.Eng. with independent resource consultants, RPA Inc., in accordance with Canadian regulatory requirements set out in NI 43-101 and CIM resource definitions.
The Three Bluffs resource is based on drilling completed between 1994 and 2012, with drill hole spacing ranging from 100m x120m down to 30m x 30m in denser drilled portions of the deposit. Wireframes were constructed of correlatable mineralized envelopes utilizing cut-off grades of 0.50 g/t Au and 1.0g/t Au. Seventeen individual wireframes were constructed for the 0.50 g/t model and sixteen individual wireframes were constructed for the 1.0 g/t model. Grade capping levels were determined separately for each domain.
Inverse distance cubed (ID3) interpolation using three progressive search volumes (15m x 15m x 5m, 30m x 30m x 10m, and 75m x 75m x 20m) on 1.5 metre down hole composites were utilized to assign gold grades to 10m x 10m x 2m blocks. Resource classification was applied using a combination of distance to nearest composite, number of holes used in the estimate, and manual adjustment based on inspection of the blocks. Inferred was provisionally assigned to any block within 75m of the nearest composite. Blocks within 30m of the nearest composite (generally within the 30m x 30m drill pattern), for which at least two drill holes contributed composites, were provisionally assigned to the Indicated category. These provisional assignments were reviewed in section and plan and manually adjusted to eliminate isolated small groups of unrealistically classified blocks.
To determine the open pit resources, a Whittle pit shell was generated on the 0.50 g/t Au model. The analysis utilized a long-term gold price of US$1,500 per ounce, process gold recovery of 93%, a calculated discard grade of 1.35 g/t Au, and pit batter angles of 50 degrees. The pit discard grade is based on break-even costs of mining, milling and G &A per tonne converted to grams/tonne Au at the gold price used for the optimization.
The underground portion of the resource was estimated from the 1.0 g/t Au model using a 5.0 g/t block cut-off.
