Silver Spruce Reports Results of 2008 Regional Exploration Central Mineral Belt (East) Properties, Labrador
- definition of anomalous stream sediment areas in U and Au
- definition of areas of minimal potential allowing reduction of claim holdings
- retention of areas of potential for 2 plus years without further exploration
April 16, 2009 - Bridgewater, NS - Silver Spruce Resources Inc. (TSXV: SSE) is pleased to report on the results of 2008 regional surveys on its 100 % owned Central Mineral Belt (CMB) East properties. Stream sediment and soil geochemistry, radon gas and ground scintillometer surveys, prospecting and geological mapping were all carried out on Silver Spruce's properties in east central coastal Labrador, 120 to 150 kilometres northeast of Goose Bay, NL. The properties include: Mount Benedict (4,058 claims); Tukialik Bay (250 claims), Jeanette Bay (60 claims), Lake Michael (57 claims), and Makkovik River (200 claims). All of these properties have either been, or are being, reduced to those areas which show the most promise based on the results of the regional surveys, allowing the areas of interest to be maintained for assessment for at least the next two years without requiring further exploration. Results are summarized below:
Jeanette Bay - A strong, coincident, uranium-lead-molybdenum stream sediment geochemical anomaly, with uranium values up to 103 ppm, was defined in the northwestern portion of the property where mapping shows the contact between Mid Paleoproterozoic foliated granodiorites and Late Paleoproterozoic massive granites, similar to the geological setting that hosts uranium mineralization at the AT- 649 zone on the Mount Benedict property. Limited ground reconnaissance found anomalous scintillometer readings in outcrop, however no sampling was carried out due to the lateness of the season. Other uranium anomalies (to 43 ppm) were located in the western section and several gold anomalies (to 33 ppb) occur on the eastern and central parts of the property. A cluster of anomalous scintillometer readings are found in the northwestern portion of the property, coinciding with the anomalous U, Pb, and Mo stream sediment values.
Lake Michael - A moderate strength, coincident uranium-molybdenum-copper stream sediment geochemical anomaly was defined in the south central part of the property. The area is flat with extensive bog cover masking the underlying bedrock. Geological mapping shows the anomaly is underlain by Late Paleoproterozoic intrusive, quartz monzonite and granodiorite, and early Mesoproterozoic gabbro and amphibolite. Moderately elevated scintillometer values are scattered over the southwestern part of the property but are non coincident with the U-Mo-Cu stream sediment anomaly.
Mount Benedict -- Anomalous stream sediment values were noted in uranium, gold, molybdenum, lead, nickel, copper and zinc. The best U anomaly, with values up to 397 ppm, is located in the northeastern part of the property, and is coincident with the AT 649 and T S7 showing areas, as a 5 to 6 kilometer, circular anomaly with elevated lead, molybdenum and silver values. Four circular coincident molybdenum, silver, copper, and locally lead anomalies, varying from 3 to 5 kilometers in diameter, also appear to be aligned at the intersection of northeast and northwest trending faults in the southeast part of the property. Strong pyrite-sericite alteration in a felsic unit with elevated Mo and Cu values, was located in the central part of the property suggesting that high level porphyries may be present. Gold (Au) values up to 47 ppb were clustered in the southwestern portion of the property. The highest scintillometer values occurred in the northeast portion of the group over the T S7 and AT 649 showings while two smaller anomalies were noted, one in the northwest and another near the center of the property. Soil sampling carried out in the AT-649 and T-S7 showing areas found uranium-copper-molybdenum-lead anomalies in the AT-649 area and moderate to high uranium values extend over the northeast trending mylonite zone for approximately 1 kilometer, including five first order values (>100 ppm), near DDH MBS7-08-05, T-S7 showing area. The anomalous trend coincides with elevated copper and molybdenum values with the southern end anomalous in lead and zinc. Radon Gas anomalous zones coincide with high uranium in soil anomalies, with a significant anomaly extending along the myloniter zone in the T-S7 area. In the AT-649 area, a small, but high strength radon gas anomaly occurs over the showing coinciding with anomalous soil and rock samples and in the southeast, high radon gas values coincide with a strong uranium-lead soil anomaly.
Regional exploration has outlined a number of significant areas of potential on the MB property including high grade uranium mineralization in granitoid intrusives at the T-S7 showing (grab sample results over 1.0 % U3O8 (20 lbs/ton)) and the AT 649 showing (5 grab samples - average grade of 0.5 % U3O8 (10 lbs/ton) and boulders downstream - values up to 3% U3O8 (60 lbs/ton)). At the T-S7 showing, drilling shows that uranium mineralization is associated with lenses of weakly sheared, biotite rich, sections in muscovite rich leuco-granites and a mineralized zone was located in a wide, north-east trending, shear zone approximately 350 meters to the north. The host rock is a mylonitized, sheared to brecciated, hematized felsic intrusive or volcanic, highly altered with carbonate, chlorite, and hematite. The best uranium intersection, in drill hole MBS7-08-05 gave 22 meters at 278 ppm U3O8 including a higher grade, 8 meter section, at 444 ppm U3O8. Radon gas surveys have defined anomalies which coincide with known mineralization at the AT 649 and T S7 targets and extend the possible strike length of the zones significantly. Anomalous uranium soil geochemistry coincides with strong radon gas values and good radon/thoron ratios. The T-S7 grid should be extended to cover the strong Rn values coinciding with high uranium in soils, which occur to the south and southeast of the mylonite zone. At the AT-649 showing, anomalous uranium and base metal values in soil samples require follow up. Radon gas values showed a strong correlation with lead and uranium soil anomalies in the southern and northern limits of the grid. The AT-649 grid should be extended to cover the strong uranium-copper-molybdenum-lead soil anomaly in the southwest and uranium-lead anomalies occurring in the southeast and northeast. The property will be reduced by over 50 % to retain only those areas of the highest potential.
Tukialik Bay - Strong stream sediment geochemical anomalies in uranium were located with most occurring in a 10 to 15 kilometer area in the central part of the claim group. The higher uranium values coincide with anomalous lead (Pb), molybdenum (Mo), copper (Cu) and silver (Ag) values. Outcrop exposure is excellent and geological mapping shows that the area is underlain by weakly foliated to massive medium to coarse grained, biotite rich, granites with accessory fluorite. Clusters of anomalous scintillometer values were noted in the central section of the property, coinciding with anomalous uranium in stream sediments. Outcrop samples showed anomalous scintillometer readings, however only weakly anomalous analytical values with high thorium / uranium ratios were found. Stream sediment samples gave low thorium values compared to the high thorium / uranium ratios reported in bedrock samples.
Makkovik River -- Limited follow up did not locate any significant, anomalous rock samples or radioactive units other than the samples located in 2007 (see News release dated August 5, 2008). Radon gas surveys were carried out over the property but results gave only weakly anomalous readings. Further exploration is dependent on compilation of all the work completed to date.
Field crews were equipped with Garmin (Rino) GPS units and RS-120 Super Gamma scintillometers. Readings were recorded as CPS (counts per second) with stations spaced at approximately 300 meters in conjunction with the stream geochemistry. Radon Gas was measured using a Pylon model AB-5R portable radiation monitor and Pylon model 300A Lucas type scintillation cells which detect alpha particles from radon (Rn) and thoron (Tn) decay, convert them to photons (light pulses) and feed them to the AB-5R monitor, which counts the light pulses and displays the results in counts per minute (CPM). All stream sediment, soil and rock analyses were carried out at the Activation Laboratories (Actlabs) facility in Ancaster, Ontario after sample preparation at the Actlabs preparation facility in Goose Bay. Uranium and other elements were analyzed by ICP with results in excess of 250 ppm uranium, follow up by analysis by delayed neutron counting (DNC) for uranium. A quality assurance/quality control (QA/QC) program, is in place to increase confidence in the results generated. A more detailed summary of 2008 exploration, compilation maps of the properties and the QA/QC criteria can be viewed on the company website www.silverspruceresources.com.
