Pacific Wildcat Resources Corp.: Results Confirm Regional Potential of the Mrima Hill Carbonatite Complex
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 02/28/12 -- Pacific Wildcat Resources Corp. (TSX VENTURE: PAW) ('PAW' or the 'Company') is pleased to announce that Mrima Hill niobium and rare earth oxide rich carbonatite along with other surrounding alkaline intrusions, principally at Kiruku Hill and Jombo Hill, are components of a single very large (17 km x 9 km) alkaline igneous complex - the Dzombo Intrusive Complex.
This conclusion is a result of a recently completed report prepared for PAW by a renowned rare earths consultant, Professor Ken Collerson. Professor Collerson based this major reinterpretation on reconnaissance magnetic and gravity data, coupled with a geochemically coherent model to explain the diverse geology of the area. This has shown that a large alkaline ultramafic intrusion links Mrima Hill with the surrounding outcropping alkaline rocks at Jombo Hill, Nguluku Hill, Kiruku Hill and Dzirihini ('Figure 1'). The discovery has substantially increased the area of prospectivity around Mrima Hill to more than 110 km2.
The Dzombo Intrusive Complex appears to be similar in size, geological complexity and prospectivity to the economically important rare metal rich intrusions on the Kola Peninsula in Russia and Finland. This discovery is a significant advance in understanding the geology and hence mineral potential of the Mrima Hill area.
In addition to the current resource drilling program at Mrima Hill, PAW and Cortec Mining Kenya ('CMK') intend to undertake an exploration program within the Dzombo Intrusive Complex to identify other areas of specialty metals, rare earth oxides, platinum group elements ('PGE'), gold, scandium, gallium and copper mineralization. PAW has a conditional purchase agreement to acquire an indirect 70% interest in CMK, owner of the Mrima Hill Niobium and Rare Earth project.
Further Key Points
-- Significant Total Rare Earth Oxide ('TREO') rock chip results of 1.33%
and 0.71% at Kiruku Hill collected over 3km from Mrima Hill ('Figure 2')
support the interpretation of the Dzombo Intrusive Complex.
-- Total count radiometric survey shows an anomaly at the northwest corner
of Mrima Hill, which has the potential for TREO mineralization. Further
anomalies correlate to the surrounding hills and show the potential for
TREO in the alluvial plain from transported eroded material ('Figure
1').
-- TREO are present at Jombo Hill and Nguluku Hill with a higher HREO and
Yttrium to LREO ratio than at PAW's drill programs at Mrima Hill.
-- Anomalous TiO2rock chip result at Jombo Hill of 3.77% and Nguluku Hill
of 2.47%.
-- TREO rock chip results of 0.17% at Nguluku over 6km from Mrima Hill.
Rock chip sampling was focused on the TREO potential from both fenitised (hydrothermal alteration to surrounding rock) and intrusive alkaline igneous rocks. PAW collected thirty-four rock chips across Jombo Hill (17), Kiruku Hill (8), Nguluku Hill (6) and the base of Mrima Hill (3) at an old quarry outside of the known mineralization zone. Twenty of these samples have been received and are listed in Appendix 1. The remaining 14 results are yet to be verified and will be released when available. The samples are indicative of the source and presence of TREO, and provide strong follow up targets for further exploration.
All sample preparation was undertaken by the Nagrom assay labs in Perth. Prepared samples were dispatched to both the Ultratrace (Nb2O5 analysis by XRF) and Genalysis (for rare earth and matrix analysis by ICP-MS) assay labs in Perth, Western Australia. Please refer to the table in Appendix 1 for a summary of results.
Potential of Kiruku Hill
In 1993, the Metal Mining Agency of Japan ('MMAJ') collected seven samples from the northeast ridge at Kiruku Hill. Although they did not assay for the full range of TREO elements and neglected to report grid co-ordinates these results are significant in identifying a mineralized area (Appendix 2). Samples collected by PAW have substantiated the anomaly identified by MMAJ. From a limited sample population PAW, has found Kiruku Hill to be favorably elevated in Heavy Rare Earth Oxides and Yttrium ('HREO') with a high ratio of 14.3% in proportion to Light Rare Earth Oxides ('LREO'). In comparison, drilling assays reported to date from Mrima Hill have a HREO and Yttrium to LREO ratio of 9.3% (Table 3). PAW drill results can be referred to in news releases NR #2011-06, NR #2011-08, NR #2011-11, NR #2011-21, NR #2011-22, and NR #2012-03.
MMAJ reported that mineralization at Kiruku Hill originated from hydrothermal activity along NW-SE regional faults and that the hill is the result of a small plug of brecciated highly baked potassium rich fenities. PAW has commissioned a recent internal review (2012) of this and other datasets by Professor Collerson who also visited the site in November 2011. His findings indicate that these fenites formed due to fluids from the alkaline intrusive complex that lies beneath the hill and 'has significant exploration potential for TREO and Nb2O5'. The Dindi and Swain 1988 historic aeromagnetic gravity survey ('Figure 1'), supports Professor Collerson's interpretation that outcropping alkaline intrusions are part of a single very large (greater than 110 km2) alkaline ultramafic intrusion at depth.
The total count contoured radiometric data sourced from Terra Surveys Ltd of Canada ('TSL') 1977, which is on a more detailed scale, confirms an anomaly at Kiruku Hill supporting the theory of an alkaline intrusion beneath it (see Figure 2).
Potential of Jombo Hill and Nguluku Hill
Work undertaken by Professor Collerson (2012) has identified Jombo Hill as having the potential for PGE associated with pyroxenites and ultramafics, as well as gold in ijolites and nepheline syenites. He has mentioned the strong possibility of Phoscorites at Jombo Hill, which have a high potential for PGE's and scandium. Jombo Hill is part of the same large intrusion that produced Mrima Hill ('Figure 1 and 3') and it lacks the laterite seen at Mrima Hill. Faulting after the major weathering event that produced the laterite blanket at Mrima Hill has exposed the exposed fresh rocks.
Professor Collerson's report has also indicated the prospectivity for copper and gallium within the region. Although no anomalies have yet identified, copper sulphide mineralization was noted by Professor Collerson in diamond drill core in fresh carbonatite at Mrima Hill.
Nguluku is a small hill composed of an agglomerate, which has the strong potential for an underlying alkaline intrusion based on xenolith (exotic rock fragment) composition and total count radiometric data sourced from TSL in 1977 (see Figure 2).
TREO's are present at Jombo Hill and Nguluku Hill with a higher HREO and Yttrium to LREO ratio (Table 3) than at Mrima Hill with HREO ratio of 9.3% based on drilling results. This is geochemically consistent with the common association of HREO's in nepheline syenites (Jombo) cf. carbonatites (Mrima). These results show the presence of TREO, the highest TREO value (0.17%) achieved at Nguluku Hill (NR006) TREO over 6km from Mrima Hill. Soils and saprolitic clays in the region therefore will form a potential exploration target.
Titanium results (JR016, 3.77% TiO2) are also anomalous around Jombo Hill and Nguluku Hill (NR006, 2.47% TiO2) indicating the likely presence of pyrochlore in the intrusion.
Mrima Quarry
Three rock chips have been taken from an old quarry on the slopes of Mrima Hill, historically used for road base and outside of the zone of known mineralisation. These samples are composed of alkaline lava flows (phonolites) and ash deposits (tuff) along the lower edge of Mrima Hill, indicating that these unweathered rocks must have been exposed by post-laterite faulting.
As expected, the results show that TREO were present at this outcrop, though not highly elevated being outside the enriched saprolite and carbonatite zones ('Appendix 1').
A New Exploration Initiative
Following these positive results, PAW plans to undertake the following exploration program to better delineate mineralized areas and the intrusive complex that formed these hills in tenement SPL256.
-- Detailed airborne regional aerial radiometric and magnetic surveys to
define the underlying alkaline and ultramafic igneous complex
surrounding Mrima Hill and the other surrounding hills. This will also
aim to identify new mineralized alkaline intrusive targets, which are
now buried and relate to the ultramafic intrusion at depth and fenitised
zones that are undercover.
-- Soil sampling, trenching, auger and or aircore drill programs to further
identify and define buried targets and any potential ionic clay
mineralization. Based on the results from these geochemical sampling
programs an exploratory reverse circulation drilling program is then
planned to be undertaken.
-- PGE potential will be further investigated surrounding Jombo Hill where
phoscorites might be present.
-- Rock chip and soil sampling, as well as mapping to better define the
genesis of the intrusions and provide further anomalies for drill
testing.
Closing Comments
PAW's President and CEO Mr. Darren Townsend commented, 'These results demonstrate the regional potential of the large intrusive complex beneath Mrima Hill. The exploration work undertaken by our geologists and Professor Ken Collerson identifies this potential and provides many new exploration targets. It is the intention of PAW and CMK to actively explore these anomalies to gain a better understanding of the potential mineralization as an addition to the company's successful work at Mrima Hill.'
