Seafield Resources Ltd. has announce assay results from an additional two drill holes at its Miraflores prospect in the multi-million ounce Quinchía District in Colombia.
- QM-DH-13 intersected 1.71 g/t gold over 17.4 metres, 1.43 g/t gold over 16.3 metres, 0.83 g/t gold over 55.05 metres, 0.85 g/t gold over 20.45 metres and 0.64 g/t gold over 42.7 metres.
- QM-DH-15 intersected 0.80 g/t gold over 261.9 metres that includes 1.45 g/t gold over 43.1 metres and 1.35 g/t gold over 41.7 metres.
During the period 2005-2007, AngloGold Ashanti Limited and B2Gold Corp. completed 3,624 metres of drilling in ten diamond drill holes at the Miraflores prospect. From 2010 to date, Seafield has completed 9,168 metres in 21 holes. Assay results are pending for QM-DH-14, and QM-DH-16 to QM-DH-21, and the Company expects to report the results from those holes when received. An additional 1,730 metres are planned for the remainder of 2011. The results until November 30th from this year's program will be included in an updated resource estimate and a scoping study being prepared by SRK in its Denver office, targeted for completion by Q1 2012.
The gold mineralization contained in the Miraflores Breccia pipe is characterized by the presence of free gold associated with the cement material of the breccias and to high grade structures where gold is associated with Zn, Pb, Cu and Fe sulphides. At surface, the diameter of the roughly-circular breccia pipe varies from 250 metres to 280 metres. Recently updated geological interpretations indicate that the breccia pipe widens at depth. The mineralization has been tested from surface to 600 m depth and still remains open. The deposit is classified as a low sulphidation epithermal deposit and is part of the prolific Mid Cauca porphyry belt.
Encouraging metallurgical test results for gravity concentration have been obtained for Miraflores ore. The Company has engaged Gustavo Meyer, a PhD Metallurgical Engineer from Colombia University with extensive experience in gold ore processing metallurgy. Mr. Meyer is establishing a program that includes the preparation of a geo-metallurgical model of the deposit.
At Miraflores, Seafield has already defined an NI 43-101 compliant resource that includes a Measured and Indicated resource of 1,227,593 ounces gold (44.7 million tonnes grading 0.9 g/t Au at a cut-off grade of 0.3 g/t Au) and an Inferred resource of 354,512 ounces gold (12.2 Million tonnes grading 0.9 g/t Au at a cut-off of 0.3 g/t Au), as previously reported in the company's press release dated May 26, 2011.
The geology and drill locations are presented in Map 1 (see below). A drill plan map and cross sections are available on the Seafield website .
