Fronteer Gold (TSX:FRG)(NYSE Amex:FRG) reports that drilling has extended a second high-grade gold-silver zone at its 100% owned Northumberland project in Nevada and announces that the contract for the construction of an underground decline has been awarded to J.S. Redpath Corporation.
The recent core drilling program at Northumberland focused on the shallower portion of the western half of the deposit where historic wide-spaced drilling, combined with new geologic modeling, gave indications of high-grade gold and silver occurring over thick intervals. The four final holes of this nine-hole (2,830 metre) drilling program were designed to test mineralization along potential NW-SE-oriented controlling structures.
Drill holes FNU40 and FNU41 are located 60 metres north and 95 metres northwest of previously-reported NUG05 (see Sept 8, 2010, press release). Drill holes FNU039 and FNU042 are situated 70 metres east and 80 metres south of FNU038.
Drill highlights include:
- 10.24 grams per tonne gold (0.299 ounces per ton) and 43.00 g/t silver (1.254 oz/ton) over 7.01 metres, including 18.64 g/t gold (0.544 oz/ton) and 97.25 g/t silver (2.836 oz/ton) over 2.44 metres in FNU40.
- 7.52 g/t gold (0.219 oz/ton) and 31.93 g/t silver (0.931 oz/ton) over 20.57 metres, including 14.48 g/t gold (0.422 oz/ton) and 22.11 g/t silver (0.645 oz/ton) over 2.90 metres in FNU41.
- 7.85 g/t gold (0.229 oz/ton) and 10.01 g/t silver (0.291 oz/ton) over 11.43 metres, including 13.88 g/t gold (0.405 oz/ton) and 24.85 g/t silver (0.724 oz/ton) over 2.29 metres in FNU39.
* Composites for broad intervals are created at 3.0 g/t gold cut off, with "including" intervals created at 10 g/t cutoff. Several values below the 3.0 gram/tonne cutoff may be included as part of the mineralized zone).

These new holes continue to expand and enhance the understanding of the distribution of high-grade mineralization throughout the deposit. Mineralization now extends north-south for a distance of 290 metres and over an average thickness of 20 metres.

Our goal is to advance Northumberland as a combined open-pit and underground mine. We aim to selectively mine the higher-grade underground sulphide resource, and mine oxide and transitional material in open pit.
Site preparation work for a 280-metre long decline to access high-grade mineralization within the deposit has now been completed and the contract for underground exploration and development has been awarded to J.S. Redpath Corporation of Sparks, Nevada. Blasting and excavation of the portal entrance is expected to commence in November.
The purpose of the decline is three-fold:
- To provide the most cost-effective method for future exploration/definition drilling and the best opportunity to assess controls on high-grade mineralization.
- To provide access for extraction of bulk samples for metallurgical testing and pilot testing at third-party processing facilities.
- To afford an easy transition from exploration to production.
In addition to the decline work, a seven-hole core drilling program is currently targeting the shallow oxide/transitional area of the deposit to obtain additional core for metallurgical testing.
James Ashton P.E. is designated as a Qualified Person for the Northumberland drill results, with the ability and authority to verify the authenticity of, and validity of these data. Drill composites were calculated using a cut-off of 3.0 g/t. Drill intersections are reported as drilled thicknesses. Drill samples were assayed by ALS Chemex (ISO9001:2000) in Reno, Nevada for gold by Fire Assay of a 30 gram (1 assay ton) charge with an AA finish, or if over 10.0 g/t (over 100 g/t for silver) were re-assayed and completed with a gravimetric finish. For these samples, the gravimetric data were utilized in calculating gold intersections. QA/QC included the insertion of numerous standards and blanks into the sample stream, and the insertion of duplicate samples at random intervals within each batch. Selected holes are also analyzed for a 51-element geochemical suite by ICP-MS/-AES.
