The Hart claims consist of over 5344 hectares (13,200 acres) of MTO claims located approximately 90 km northeast of Dease Lake, covering the source area of multiple highly anomalous, continuous, government sponsored stream samples. The samples test drainages from over a 10 km strike length of the Eocene alkaline feldspar (alaskite) Major Hart pluton at the contacts with both argillaceous Slide Mountain volcanics and sediments and a Devonian to Permian ultramafic body. The broad contact zone, within and adjacent to the pluton contact, is considered to be highly prospective for economic concentrations of Rare Earth Elements, Strategic Metals, and possibly Emeralds near the contact with the ultramafic rocks. The pluton is a one-of-a kind Eocene intrusive located between the Kechika Fault and the Kutcho Fault in the Sylvester allochthon, in an area of intense and prolonged crustal deformation during the formation of British Columbia.   Several British Columbia Geological Survey regional stream samples, assayed by neutron activation and collected in the area of the claims, are in the upper 1% threshold in the 1:250,000 scale 104I map sheet for anomalous Cerium, Lanthanum, Lutetium, Rubidium, Tantalum, Terbium, Tungsten, Ytterbium, and Fluorine in Water. Most of these samples dominate the top ten, or are included in the top twenty samples numbers in the list for several of the above minerals. Several of these samples rate highly in the top 1% and even the top 0.1% of the province-wide anomalous threshold in many of the same elements (out of approximately 53,000 samples). Rare earths, and other rare high value minerals such as Beryllium, Dysprosium, Erbium, Europium, Gadolinium, Holmium, Lithium, Neodymium, Praseodymium, Promethium, Thulium, and Yttrium, have never been analysed for, but many are considered to be likely to be found in the Hart claims area considering the suite of indicator minerals found here to date. Although there are a small number of samples distributed over the large area, some degree of zonation of the rare minerals is indicated by the stream sample results. The stream sample anomalies are particularly elevated in the High Field Strength Elements, a group of elements which include the more valuable and rare Heavy Rare Earth Elements. The suite of anomalous rare elements indicates a highly evolved and fractionated intrusive melt, the type which has been known to form REE -rich pegmatite deposits. Bismuth and Tungsten anomalies indicate a strong possibility of an additional zone of greisen or skarn potential.   Aside from GSC 1:250,000 scale mapping, and the recent BCGS 1996 stream sample survey, no work has been recorded in the claim area. Considering the tenor of the anomalous stream sample results, the potential for an incredible new discovery in BC in the Hart claims is nearly unprecedented. Emeralds are sometimes formed where volatile granitic fluids (often containing many rare minerals) intrude, or are destabilized by, interaction with chromium-rich ultramafic rocks. Approximately 5 km of a large Devonian to Permian (older) ultramafic body is in contact with the mapped Major Hart pluton within in the claim area, where the pluton shows the highest overall amounts of anomalous rare elements in stream samples. The Major Hart granite has been noted as being miarolitic (containing many open spaces which are often filled with concentrations of rare pegmatite-like mineral assemblages), and this is one of the best environments to locate gem quality material within a granitic environment, as well as concentrate other, more strategic, minerals. Beryllium has never been sampled for in the claim area, however several emerald occurrences are noted to the north of the claim area, and continuing to beyond the Yukon provincial border.   Sample 104I955137 is located on a creek draining the centre of the claim has the 4 th highest RGS Ytterbium, 12 th highest Lutetium , and the 21 st highest Terbium in the provincial database of over 53,000 stream samples . Bismuth is the 34th highest of the 14,500 samples analysed for Bismuth by the BCGS. Sample 140I955135 is located on a creek draining the claims on the opposite side of the ridge from 104I955137, 5.6 km away, has the 4 th highest Rubidium, 9 th highest Tantalum , 35 th highest Ytterbium, and the 68 th highest Tungsten in the provincial database. Bismuth is the 5th highest of the 14,500 samples analysed for Bismuth by the BCGS. In fact, all 7 samples draining the property are in the top 1% for Bismuth. Of the entire provincial database, RGS stream samples draining the Hart claims (listed below) feature: Rubidium:     all seven are > 99.9th percentile anomalies Tantalum:     all seven are > 99.9th percentile anomalies Ytterbium:     5 are > 99.9th percentile anomalies Lutetium:       3 are > 99.9th percentile anomalies Terbium:       2 are > 99.9th percentile anomalies Tungsten:     2 are > 99.9th percentile anomalies In the 1:250,000 scale map sheet   NTS 104I (containing approximately 900 INNA samples), samples draining from the claims area and immediate vicinity rate: Ce - Cerium             3 samples in the top (highest) 16 samples, 5 samples in the top 18 samples La   - Lanthanum    1 sample in top 5, 2 samples in top 12 samples Lu   - Lutetium        The top 3 samples, and 8 of the 9 top samples Rb - Rubidium         The top 7 samples, 9 of the top 11 samples Ta  - Tantalum        The top 7 samples Tb - Terbium          The top sample, 2 samples of the top 4 , 3 samples of the top 11 W   - Tungsten        4 samples in the top 11 samples F - (Fluorine) in water             6 samples of the top 9 samples Multiple equal analysis values counted as one sample rating level. -1 (below) indicates analysis not performed.

.   Recent NEWS May 11, 2011 08:42 ET Two Large, Rare Earth Anomalous Areas Defined on Silver Grail's Major Hart Property VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 11, 2011) - Silver Grail Resources Ltd. (TSX VENTURE:SVG) (FRANKFURT:KD7) ("SVG") is pleased to announce results from the heavy mineral sampling program conducted over the Major Hart property, located 90km northeast of Dease Lake, BC. Heavy mineral sample results are used to gain knowledge of mineral types, phases, and grain sizes to improve follow-up targeting, and to increase the contrast to background values where dilution by extensive till or other environmental factors may mask potential anomalies that may not be obvious when using other types of reconnaissance geochemistry methods. The results received are considered to be exceptionally high in some elements notwithstanding the concentration due to the method. The tin results are particularly high in several samples, up to just under 20%, while total rare earth element oxides including Y exceed 10% in certain samples. Examination of the results obtained in the late 2010 Major Hart program indicate a highly anomalous trend ("Main Anomaly Area") within the granite surrounding the intruded contact with the ultramafics, which is fully contained in the north of the claims area. The anomalous area is loosely defined as a two to three kilometre wide belt containing large amounts of fluxing agents and unusual elements such as boron, fluorine, lithium, tin, tungsten, bismuth, niobium, yttrium and REEs. The density of samples has not yet fully constrained the area to less than 20 km(2) at present. The contact with the ultramafic rocks appears to have caused a strong reaction zone along the interface area with the intruding granite, which geochemistry shows to be near saturation levels in some elements, especially as the granitic melt cooled. The ultramafic rocks are of such a contrasting composition to the evolved granite melt that "chemical quenching" of the volatile and incompatible element-rich fluids may have caused rapid deposition of large volumes of unusual mineral assemblages. Tungsten skarns, tin greisens, pegmatites, and potential gemstone occurrences are considered to be possible within the north ultramafic contact belt. A second anomalous area ("South Anomaly Area") is contained within the Major Hart claims, and is located south of the main anomaly. The general relationship of anomalous samples to topography suggests that a phase of the granite is REE-enriched in a mid-elevation belt around the southern extent of the northeast lobe of the Major Hart Pluton, but does not carry the majority of the rare metals that are ubiquitous in the ultramafic contact belt. The south trend appears to primarily contain zirconium, REEs, and moderate or spotty high beryllium values. One heavy mineral sample on the north end of this belt does contain considerable amounts of tin, and the relationship with the north belt here is uncertain. There may exist a continuum from one type of mineralization to the other, where the south area melt possibly contained similar volatile magmatic chemistry to the north, but was not destabilized by contact phenomena, and therefore has cooled in a more systematic manner. Large interior pegmatites could form in this environment, or sub-pegmatitic granitic phases with very highly differentiated chemistry from the bulk of the pluton. The area containing the southern anomaly is loosely constrained within approximately 12 km(2). Potassium in the southern area is reduced compared to the north, while sodium, calcium and phosphorus show moderate reciprocal increases, suggesting some sort of modification of the bulk granite chemistry has occurred.

The limited whole rock data to date suggest that the general geochemical characteristics of the Major Hart Pluton shares similarities to the Separation Rapids Batholith in Ontario (host to the Big Whopper Pegmatite), parts of the Surprise Lake Batholith in northwest British Columbia ( host to over 100 Minfile showings), and the tin granites of Cornwall England, Thailand, southern China, and parts of north Alaska. Major differences exist from most granites of "similar" geochemistry, not the least of which is the very young age of 48 Ma, and the apparent absence of muscovite mica. The granite has strong similarities to topaz rhyolite compositions, mostly due to the very high silica content, which is greater than 75% on average. Boron was not analysed in granite samples but exceeds 1% B2O5 in five of the thirteen -32I heavy mineral fractions, to a maximum of 3.41% B2O5. Methodology: The 10 kg heavy mineral samples were processed by CF Mineral Research, Kelowna, and separated into several discrete fractions by a combination of specific gravity and grain size criteria. Several fractions obtained from each heavy mineral sample were analysed by Actlabs, in Ancaster, Ontario by various methods dependant on fraction size, expected mineralogy, and desired element requirements. Methods utilized included sodium peroxide fusion ICP/MS, lithium fusion ICP/MS, neutron activation, selective ion (for fluorine), and XRF packages. A large number of the samples returned results in the percent range for several elements of interest, especially the -60HN (minus 60 mesh, heavy non-magnetic) and -32+60HN (minus 32 mesh to plus 60 mesh, heavy non-magnetic) and the -32+60HP (minus 32 mesh to plus 60 mesh, heavy paramagnetic) fractions. The intermediate specific gravity, -32mesh fraction (-32+60I) was the only fraction analysed for boron and lithium, due to analytical constraints and the range of minerals that were likely to occur in this fraction. "Heavy" minerals, as used in the analyses, are those that exceed a specific gravity of 3.32 g/cm(3). The intermediate (-32I) fraction contains minerals with a specific gravity between a 2.92 and 3.32 g/cm(3). Nb, Sn and Zr results above are reported in XRF values where available. Elemental results not received from the laboratory as oxides have been converted to oxide format using formulas obtained from the British Columbia Geological Survey website, and the University of Maryland Geology Department website and are believed to be accurate. Chondrite normalized REE patterns of all samples collected from within the pluton exhibit a classic "seagull" pattern with a very strong negative Eu anomaly and a relatively flat to slightly upturned HREE pattern. LREE2O5 indicates combined LREEs in oxide format, and HREE2O5 indicates combined HREEs in oxide format. Cerium is the largest component of the LREEs in most cases, followed by lanthanum. Lutetium was not available in the -32I fraction analyses. D. Cremonese, P.Eng., is the Qualified Person for the purposes of this news release. D.
