“Seizing Opportunity and Creating Value”
Dec. 30, 2010 (TheNewswire.ca) --
- 73 line kilometers of ground geophysics (magnetic, VLF and radiometrics) completed
- Anomalous magnetic and VLF-EM trends identified across the surveyed area
- Radiometric results pending
December 30, 2010 - Bridgewater, NS - Silver Spruce Resources Inc. (TSXV: SSE) is pleased to announce that the ground geophysical surveys on the 100% owned Popes Hill (PH) REE property located on the Trans Labrador Highway (TLH) in south central Labrador, has been completed. The 73 line km geophysical survey, which consisted of magnetics, VLF-EM and radiometrics was carried out under contract by Abitibi Geophysics of St Johns, Newfoundland. The surveys were focused on the original 62 claim block, which covers a 5 kilometer long trend of rare earth mineralization located in bedrock and angular boulders along and just to the north of the TLH. The surveys included GPS controlled magnetics, with readings taken every 2 seconds, VLF-EM with readings at 12.5 meter spacing and radiometrics, also at 12.5 meter spacing, over selected areas, covering some of magnetic and electromagnetic anomalies located. The rare earth mineralization is variably non magnetic to magnetic and is associated with thorium/uranium making the samples radioactive and therefore responsive to radiometric surveys. The REE mineralization may also be shear hosted and the shear systems may respond to the VLF-EM survey.
Preliminary plots of the magnetics and VLF-EM show a number of linear magnetic anomalies, both positive and negative, crossing the property in an ENE direction. A number of the VLF-EM anomalies are coincident with, or marginal to, the magnetic highs with others in the magnetic low areas. A VLF-EM anomaly, between magnetic high zones, possibly indicating a shear system, occurs coincident with the anomalous REE samples in the bedrock aggregate pit on the side of the TLH and extends along strike to the east and west. All geophysical data will be compiled over the holiday period and the final results will be released early in the New Year. Once the geophysical targets are defined, an application for a diamond drill program, to be carried out early in the New Year, will be submitted to the Newfoundland government.
The original PH 62 claim property (1,550 ha) is located in the Pope's Hill area, approximately 100 km from Goose Bay along the paved portion of the TLH. The claims were acquired to cover thorium and REE mineralization located in 2006 during uranium exploration when values of up to 7.9% total rare earth elements plus yttrium (TREE+Y) were located (see news release dated May 6, 2010). Thirty-one samples were taken in follow up exploration in October (see news release dated Oct. 28, 2010). All samples gave anomalous TREE+Y values with 16 > 5%, and 5 > 10% with a high value of 24% TREE+Y. TREE+Y values varied from a low of 0.07% to a high of 24.07% averaging 5.73% for the 31 samples, which included 7 "host rock" samples, with values < 0.2 %. The anomalous trend has been traced over a 7 km strike length extending to the east, approximately 4 km, and to the west, approximately 3 km, from a bedrock aggregate pit on the TLH. The highest REE values are in a dark grey to black sub-metallic mineral in veins which are variably non magnetic to moderately magnetic. All of the REE bearing samples are weakly to moderately radioactive with significant thorium content and minor uranium values generally < 100 ppm.
Rock units on the claims are mapped as granitic to mafic gneisses of late Paleoproterozoic age, with some pegmatites. Linear monzonite bodies, possibly related to a major structure, lie just to the north and south, along strike, of the mineralized area. Syenites and/or granitic units of peralkaline affinity have been noted.
Work has also begun, in co-operation with Dr. John Hanchar, P.Geo., Professor and Head of the Earth Sciences Department of Memorial University of Newfoundland, who is an expert in the study of REEs, and on the identification and characterization of the minerals carrying the REEs. These studies will continue over the winter months with results released periodically as data are generated.
