Spanish Mountain Gold Ltd. ("the Company") (SPA-TSXV) is pleased to announce an updated resource estimate (National Instrument 43-101 compliant) for the wholly owned Spanish Mountain Gold Project (the "Project") in central British Columbia, Canada. This resource estimate is an update to the previous estimate disclosed by the Company in a news release dated November 23, 2010, following the completion of a Preliminary Economic Assessment ("PEA") for the Project.
The updated resource at selected gold cut-off grades is as follows:
Spanish Mountain updated resources (at a 0.30 g/t gold cut-off)
|Measured plus Indicated||91,090,000||0.62||0.64||1,820,000||1,870,000|
The PEA had established an economic cut-off of 0.2 g/t gold based on assumptions of operating costs for a potential open pit operation. These assumptions will be refined within the pre-feasibility study which is currently underway. The following table presents the updated resource at a cut-off grade of 0.2 g/t gold.
Spanish Mountain updated resources (at a 0.20 g/t gold cut-off)
|Measured plus Indicated||138,030,000||0.49||0.64||2,170,000||2,840,000|
Tonnages and contained ounces presented above may not total as shown due to rounding. Readers are cautioned that mineral resources, which are not mineral reserves, do not have demonstrated economic viability.
- A significant increase in Inferred resource has occurred within the North Zone. A revised geological model for the North Zone now portrays a near vertical or steeply south dipping orientation for this zone.
- There are clearly defined areas for future in-fill drilling to aid in re-classification of inferred ounces within the resource.
- Mine planning for extraction of higher grade near-surface gold mineralization within potential starter pits will be optimized during the pre-feasibility study.
- The schedules for completion of the pre-feasibility and feasibility studies remain unchanged.
Brian Groves, President and CEO said today: "The updated resource estimate has identified a significant increase in inferred resources on the Property. Our current understanding of the North Zone represents a distinct change from the previous assumptions regarding the orientation of mineralization within this zone. In addition, the data from the recently completed infill drilling program have revealed improved continuity in this mineralized body. While work continues towards the completion of the Prefeasibility Study, we will now also focus on the objective of drilling within this zone and adjacent to the Main Zone to enable a re-classification of inferred resources to the measured and indicated categories."
Details of the parameters used in the resource estimate are as follows:
- Out of a total of 674 drill holes provided, 528 diamond drill holes penetrated the various geologic solids. Missing or unsampled intervals were filled with 0.001 g/t gold. Samples not analyzed for silver from earlier drill campaigns were left blank.
- A three dimensional geologic model was produced by the Company's geologist using Vulcan 3D mining software. The main zone mineralization was modelled into an upper argillite unit, an altered siltstone unit, a tuff unit and a lower argillite unit. The North zone argillite was a separate solid. All material outside of these domains was considered waste.
- The gold grade distributions within the mineralized domains were examined to determine if capping was required. In each case the distribution for gold was strongly skewed. A lognormal cumulative frequency plot was produced for gold in each domain and in all cases showed multiple overlapping lognormal populations. Capping levels were determined to reduce the effect of small high grade populations that can be considered erratic. A similar procedure was used to cap silver values.
- Gold and silver were modelled separately for each geologic domain using pairwise relative semivariograms.
- A block model with blocks 15 x 15 x 5 meters in dimension was superimposed over the mineralized geologic solids.
- Ordinary kriging was used to interpolate grades into blocks within the mineralized solids. In all cases, the kriging exercise was completed in a series of four passes with the search ellipse for each pass being a function of the semivariogram ranges.
The completed National Instrument 43-101 compliant report will be available under the profile of the Company on SEDAR within 45 days.
The Company will now focus on the completion of additional in-fill drilling, principally within the North Zone and adjacent to the Main Zone with the objective of enabling a re-classification of part of the inferred resource to the measured and indicated categories.
This drilling will not affect the ongoing Prefeasibility Study for the Project, which is scheduled for completion in April 2012. The Company also expects to have the in-fill drilling and an updated resource estimate completed in April 2012, at which time it intends to commence a Feasibility Study for the Project.
All core samples were fire assayed at ALS Chemex Laboratory in Vancouver, BC.
