INTRA ENERGY CORPORATION LIMITED Intra Energy Corporation Limited provided an update on exploration being carried out at its Yalgarra Project in the Murchison region of Western Australia. Initial multi-element assays for the first 15 rock chip samples have been received, with the tenor of the results supporting potential for fertile mafic and ultramafic host units within the Project, further validating Soil Geochemical Prospects /targets identified. Soil Geochemical Sampling The first batch of assay results received from the Soil Geochemical Sampling Program identified three prospects in the Northern Block of the Licence, Yallalong South, Bert Well and Hillside, as per the reporting Project-wide Soil Geochemical Sampling.
Results Whilst undertaking Soil Geochemical Sampling, geologists were able to map the geology and collect rock chip samples. Many of these samples were iron-oxide samples with vuggy textures that were collected as possible gossans, with some of the samples collected to be able to discriminate between weathered ultramafic, mafic and felsic volcanic rock units; and several Samples of pegmatite were collected to analyse for lithium anomalism. A total of 87 samples were collected and 15 have been returned to date.
Discussion: The Company noted that samples RS001 through to RS012 are all from the Yallalong South Prospect Area. Out of all of the samples RS007 has the highest copper content with 276.8ppm copper with minor 0.15% sulphur content suggesting possible magmatic sulphide source. In this sample, the mafic elements (Cr, Mg and Fe) are more indicative of a mafic precursor rather than an ultramafic precursor.
Although chromium, magnesium and nickel concentrations in samples such as RS001 (potential Magnesite present), RS004 and RS012 are indicative of the presence of ultramafic rocks in the same general prospect area. Samples RS013 through to RS015 are from the Bert Well Prospect Area, with the assay results for sample RS014 not yet returned. Sample RS015 recorded 213ppm copper and was associated with an elevated zinc concentration of 710ppm and cobalt at 162ppm.
Notwithstanding, the prospect has in general an extensive transported sand regolith, and at the sample site location RS015 was a vuggy iron-oxide rich sample found near the contact of mafic volcanic and possible felsic volcanic rocks (with beige colouring with prominent `quartz eye' mineral habit). A nearby BIF unit also hints that a remnant keel of a greenstone sequence is present at Bert Well. No assays have been returned from rock chip samples from the Hillside Prospect yet.
A single assay from Sample RS016 was returned from a sample site near the field camp in the Southern Block, which is a vuggy textured iron-oxide (potentially gossan) sample with 162.4ppm Cu concentration, as well as elevated 35.8ppm Pb, 219ppm Zn and 0.27% Sulphur content suggesting a chalcophile and possible magmatic sulphide association. The sample has an extremely high 60.81% iron content with elevated 1,812ppm vanadium content and 148.1ppm cobalt content, though the modest 58ppm chromium assay suggests a mafic gabbroic precursor rather than an ultramafic precursor. Next Steps: While the Company is awaiting soil sampling results from Yalgarra's Southern Block and further sample assay results, it will forward selected Samples for petrologic and electron-microscope evaluation for evidence of magmatic sulphides.
IEC intends to commence further field exploration in February 2023, with the intention to focus in on high-priority drill targets for testing in the second half of 2023.
