Bushranger Project – Footrot prospect update


The Board of Xtract Resources Plc (“Xtract” or the “Company”) is pleased to report on results of a MIMDAS IP geophysical survey at the Footrot prospect on the Bushranger copper-gold exploration project, located in the Lachlan Fold Belt (“LFB”) of New South Wales, Australia.


·    A MIMDAS IP geophysical survey has just been completed across the Footrot prospect, 7km southeast of Racecourse, indicating a large chargeability anomaly extending for over 1km on a similar N-NW trend to Racecourse

·    Such chargeability anomalies at Racecourse are related to strongly developed pyrrhotite-pyrite mineralisation with associated copper

·    The target occurs within an area of historic copper soil anomalism and altered porphyritic intrusives which could have similarities to the Racecourse deposit setting

·    The data will be fully reviewed with the aim of siting a reconnaissance drill hole to test the target as part of the Phase Two drilling programme at Bushranger

Colin Bird, Executive Chairman said: “We are pleased that the Footrot prospect is demonstrating a similar geophysical signature to Racecourse. Arising from the Phase One drilling programme and geophysics testing at Racecourse we have learned much about the mineralisation patterns relative to geophysical models. In addition, we have learned that strong pyrrhotite and pyrite mineralisation is a good indicator for copper mineralisation. We plan to undertake further geophysics using drone technology over the Racecourse project whilst identifying the best drill site to test the Footrot geophysical signature.”

Footrot MIMDAS IP/Resistivity Survey Background

At the Footrot prospect, approximately 7km southeast from Racecourse, the Company has recently received the 3D IP resistivity and chargeability model which incorporates two new lines of MIMDAS data plus two lines of IP/MT geophysical data which were collected by Anglo American Exploration Australia Pty Ltd in 2014.  This combined data set shows a large chargeability anomaly over more than 1km length at about 500m depth in the west of the prospect area. Historical surface geochemistry (soils and aircore drilling) shows a copper anomaly associated with this chargeability response, and a drill hole in 2014 hit altered porphyritic monzonitic intrusives, possibly suggestive of another mineralised porphyry system in this area, thereby highlighting a strong target for testing later in the Phase Two drilling programme.

The following is a summary of technical terms:

“Au” Gold
“Cu” Copper
“Inferred Mineral Resource” That part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes
