Pacific Wildcat Resources Corp.: Initial Niobium Resource Estimate for Mrima Hill Exceeds 1.5 Billion Pounds

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 7, 2011) - Pacific Wildcat Resources Corp. (TSX VENTURE:PAW) ("PAW" or the "Company") is pleased to announce the initial NI 43-101 compliant independent Niobium mineral resource estimate report for the Mrima Hill Niobium and Rare Earth Project in Kenya.

The mineral resource estimate was prepared by ExplorMine Consultants ("ExplorMine") of Johannesburg, South Africa. The table below shows the results of the mineral resource estimate as follows:

Mineral Resource Tonnes Average Nb2O5 Pounds
Category (Millions) Nb2O5(%) (millions)
Measured - - -
Indicated - - -
Inferred 105.3 0.65 1,519
  1. Mineral Resource tabulation for Nb2O5 for Mrima Hill, Kenya at a 0.2% Nb2O5 cut-off. Figures have been rounded off to the appropriate level of accuracy.
  2. The effective date of the mineral resource estimate presented above is 6th July, 2011.
  3. This mineral resource estimate includes technical information which requires subsequent estimates to derive totals and weighted averages. Such estimations inherently involve a degree of rounding and consequently introduce a margin of error. Where these occur, ExplorMine does not consider them to be material.

The Niobium mineral resource estimate is from surface down to a maximum depth of 30 metres with 83% of the mineral resource tonnes being found in the top 20 metres. ExplorMine are of the view that with additional surface survey information a significant portion of the inferred classification may be able to be reclassified into the Indicated category.

As can be seen from the mineral resource estimate grade tonnage curve below, a significant portion of the mineral resource is high grade with 12.0 million tonnes of mineralisation having a grade of 1.21% Nb2O5 at a 1.00% Nb2O5 cut-off grade.

PAW's President Mr. Darren Townsend commented, "We are very pleased with this initial Niobium mineral resource estimate given how shallow the mineral resource is as well as the high grade nature of the deposit. It shows the large size potential of the deposit and I am confident the 1,500 metres deeper diamond drilling program we are currently undertaking will continue to show the depth potential of the deposit."

Mineral Resource Estimate Methodology

The mineral resource estimation methodology was Ordinary Kriging interpolation of blocks with a block size of 100m (x) x 100m (y) x 2.5 m (z). A well-defined grade model was obtained by constraining the upper limit of the Nb2O5 95% confidence limit spread to 30%. The horizontal extent of the Resource was constrained by historical geological mapping by Anglo American.

The mineral resource estimate is based on:

  • A database of 31 RC drill holes drilled by PAW during 2011 and the results are summarized in Appendix 1.
  • A database of 410 Anglo American pits from 1955 generally sunk to approximately 9m depth from surface.
  • All RC drill hole assays were performed by Ultra Trace Assay Labs in Perth using XRF assay techniques for niobium.
  • Historical Anglo American assays were undertaken locally in Kenya under Anglo American supervision using chromatographic techniques with regular checks in the central South African laboratory using both spectrophotometric and chromatographic techniques. An extensive validation exercise was undertaken by ExplorMine to confirm that these assay results could be used in the mineral resource estimate.
  • Specific gravity used the overall mean of 1.84 t/m3.
  • Geological losses of between 10 and 15% have been applied depending on mineral resource estimation confidence levels.
  • All grades are based on weight percent.

The Niobium Market

Niobium is an advanced metal used in a variety of uses including high strength, low alloy steels. "Niobium represents a small percentage of the raw material cost of steel making, but adds significant value by improving strength, durability, weight and flexibility. Substitutes, such as ferrovanadium have inferior physical characteristics and comparatively higher prices and generally lower added value, mitigating the risk of substitution" (IAMGOLD 4 May 2011. Niobium consumption has increased at approximately double the rate of steel over the past 10 years and the current FeNb price is approx. US $ 46/kg Nb (source Metal Pages – Ferro Niobium 65% - 30/6/11).

About the Mrima Hill Project

The Mrima Hill Project is located in the southeast of Kenya and is 70 kilometres south of Mombasa, the largest port in East Africa. The ground area covered by the Mrima Hill licences is 1,180 sq. km.

Mrima Hill also has significant Rare Earth Oxide ("REO") mineralisation located coincidently and in close proximity to the Niobium deposit at Mrima Hill. Binge FW (1955) reports a total of 32 million tonnes of mineralisation at 3.1% REO in the surface weathered profile down to approximately 8m depth (for further details refer to press release dated 23rd July 2010 and titled "PAW enters into conditional purchase agreement with the right to acquire the majority of a large scale Niobium/Rare Earth metal project").

Note that the potential quantities and grades of the above REO estimates are conceptual in nature, and there is insufficient exploration to date to define a mineral resource and therefore it is uncertain if further exploration will result in the target being delineated as a mineral resource.

A NI 43-101 compliant technical report is currently being prepared and will be filed on SEDAR within 45 days of the date of this press release.


Darren Townsend, President

Investors are cautioned that trading in the securities of Pacific Wildcat Resources Corp. should be considered highly speculative. Cautionary note: This press release contains forward looking statements, particularly those regarding cash flow, capital expenditures, work programs, the estimation of mineral resources and the Company's plans with respect to the exploration and development of its projects and its investment plans. By their nature, forward looking statements involve risk and uncertainties because they relate to events and depend on factors that will or may occur in the future. Actual results may vary depending upon exploration activities, industry production, commodity demand and pricing, currency exchange rates, and, but not limited to, general economic factors. There can be no assurance that the Company will be able to obtain a mining licence or any of the permits that are required in order to commence mining operations at the Mrima Hill Project. The rare earths historical resource estimates is considered speculative and therefore non-compliant with National Instrument 43-101 ("NI 43-101") reporting standards and should not be relied upon. The Company is not treating the historical estimate as current mineral resources or reserves. The Company has not undertaken any independent investigation of the historic rare earths resource estimates. The Company believes that these historical resource estimates provide a conceptual indication of the potential of mineral occurrences within the project and are relevant to ongoing exploration. The Company intends to confirm the historic resource estimates through drilling as soon as possible.
