Search Minerals Inc. Discovers Heavy Rare Earth Element Mineralization in the Port Hope Simpson REE District, Labrador

Jul 7, 2010

VANCOUVER, BRITISH COLUMBIA--(July 27, 2010) - Search Minerals Inc. (TSX VENTURE:SMY) ("Search" or "the Company") and its wholly owned subsidiary, Alterra Resources Inc. ("Alterra"), have discovered heavy rare earth element-enriched (HREE) mineralization on the Island Prospect in the Port Hope Simpson (PHS) REE district in SE Labrador. In addition, initial results from the Fox Harbour Zone, approximately 12 km east of the Island Prospect, indicate the presence of light rare earth element-enriched peralkaline volcanic units.

Highlights: (See Tables 1 & 2 for details)

  • The Island Prospect and the Fox Harbour zone become the focus of increased exploration activity;

  • The Island Prospect has rare metal-enriched mineralization including HREE (e.g., Dy up to 3,780 and Er up to 2,330 ppm), Zr (up to 32,790 ppm), Y (up to 19,480 ppm) and Nb (up to 20,300 ppm); and

  • The Fox Harbour zone, contains rare metal-enriched peralkaline volcanic units, with sampling returning high Zr (up to 19,330), high Y (up to 1,490 ppm) and high LREE (e.g., Ce up to 6,800 ppm);

At the Island Prospect, mineralization occurs in pegmatite-aplite dykes and veins from 2 cm to 1.5 m wide. Smokey quartz and magnetite occur along with unidentified REE, Nb, Y and Zr minerals throughout the mineralized dykes. The main mineralized zone is roughly 300 x 300 m, although mineralized dykes occur throughout a zone about 1.2 km long. The rare metal-enriched mineralization includes high HREE (e.g., Dy up to 3,780 and Er up to 2,330 ppm), Zr (up to 32,790 ppm), Y (up to 19,480 ppm) and Nb (up to 20,300 ppm) values (Table 1).

Trenching, detailed geological mapping and an extensive sampling program are currently underway to evaluate this prospective area and to spot drill hole locations. Channel samples, 8 cm. wide and 10 cm deep, are also being taken to evaluate vein densities and between-vein grades.

The Fox Harbour Zone of the Port Hope Simpson REE district, located 12 km east of the Island Prospect, is an elongate zone approximately 20 km by 3 km. Reconnaissance mapping and prospecting has identified at least 4 linear units, from 1 to 100 m wide, of fine grained granitic gneiss that are tentatively identified as peralkaline volcanic rocks. These units give variable but anomalous values of rare metal elements such as Zr, Y, Nb, and LREE (Table 2). A detailed mapping and sampling program is currently underway to delineate the peralkaline units and to identify the most prospective zones for REE and the other rare metals (Zr, Y, Nb, Ta).

Jim Clucas, President and CEO of Search notes; "Our initial basis for assembling such a significant land package in the PHS Belt is being borne out by these early results. Our geological model envisages both smaller, higher grade, vein/dyke-hosted deposits and larger, medium to lower grade, deposits with the potential for significantly higher tonnage. We are extremely encouraged by the stellar efforts of our field team in advancing our program so rapidly and with such significant results. The widespread presence of Heavy Rare Earths at the Island Prospect is very promising."

Both the Island Prospect and the Fox Harbour peralkaline volcanic rocks occur within 1 km of an all season, maintained, gravel highway. The Fox Harbour volcanic rocks stretch up to 20 km west of the port community of St. Lewis and its small aircraft landing strip. The Island Prospect is within 20 km of Mary's Harbour and its small aircraft landing strip.

In addition to the two prospective areas reported above, at least 5 other zones with little or no geochemical data are the focus of on-going prospecting and sampling programs.

A further 66 claims have been staked in the district as a result of reconnaissance prospecting and sampling. Geochemical data are expected from these new prospective zones in the near future.

Lithogeochemistry samples, all from bedrock, are collected by Company personnel, bagged and described. Reference samples are also collected for each grab, lithogeochemistry and channel sample. The samples are delivered by Search personnel to Activation Laboratories Ltd. (ActLabs) sample prep facility in Goose Bay, where they are crushed to 80% -10 mesh and riffled to produce a representative sample. This sample is then pulverized to 95% -200 mesh with the pulverizing mills being cleaned between each sample with cleaning sand. The samples are then shipped by courier to the ActLabs analytical facility at Ancaster, Ontario. A representative sample is treated by a lithium metaborate/tetraborate fusion and then analyzed by ICP and ICP/MS techniques. Mass balance is required as an additional quality control technique and elemental totals of the oxides should be between 98% and 101%. For QA/QC purposes Search requires duplicates every 25 samples and two Search reproducibility standards every 50 samples. ActLabs analyzes duplicates and splits approximately every 15 samples and also analyses 29 measured standards for QA/QC. To further enhance our QA/QC procedures Search intends to establish a program of checking analytical results with other labs to confirm the ActLabs results. ActLabs is a ISO/IEC 17025 accredited laboratory.
