Macarthur Minerals Limited (TSX-V: MMS) (ASX: MIO) Joint Venture Partner, Fe Limited has received encouraging results from its first phase preliminary drilling at the Hillside Project in Western Australia targeting underground extensions to the periodically outcropping mineralised gossan identified during previous reconnaissance. A total strike length of 14km was mapped and sampled at outcrop resulting in high grade rock chip results as reported in ASX announcement October 9, 2019.
A total of 1798m from 36 holes were drilled at approximately 1km intervals targeting underground extensions to the periodically outcropping mineralised gossan identified during previous reconnaissance.
Limited historical targeting data was available, and first pass hole locations were chosen using estimated dip and dip direction from the interpreted lineament of the mineralised strike. Supporting information included field observations, a coincident westerly dipping magnetic anomaly with its eastern extent coinciding roughly with the interpreted gossan lineament and the presence of highly leached surface lithologies indicating the possibility of sulphides at depth.
The Company has now received all results of the assays and initial interpretation shows three holes have been positively identified to have intercepted down dip extensions of the surface gossan. These holes span the entire length of the mapped strike length demonstrating down dip extension of the surface mineralisation.

Guidance for next phase planning
Grades in all intersections show strongly anomalous mineralisation and provide valuable guidance for hole location in the next phase of drilling. Planning for the next phase of exploration will be completed following full interpretation of initial assay results.
The central and northern most holes intercepted the anomalous zone towards the end of the respective holes which indicates why some of the other planned holes failed to intersect the target.
The southernmost hole intersected a wide zone of anomalism from 23m down to 42m with increasing levels of zinc continuing below.
All three holes intersected anomalism below the optimal supergene and enrichment zones. This information will allow more accurate dip data to be used in locating further follow up drilling and target depths which will attempt to intersect supergene and enrichment zone mineralisation. Figures 2, 3 and 4 show cross sections of the intersecting holes with the interpreted target body and show where other nearby holes failed to intersect
Anomalous gold grades
In addition, one hole towards the northern extent of the project area returned strongly anomalous gold grades from targeted drilling in known gold bearing quartz veins.
As the quartz veins are host to nugget gold, the anomalous grades returned can be considered significant and represent the presence of fine gold given no visible gold was logged.
Fe Limited’s initial preliminary drilling was conducted along the total strike length of 14 kilometres that was mapped and sampled at outcrop resulting in high-grade rock chip results.
Fifteen samples gathered were from outcropping gossan both with and without visible copper minerals with a high sample result of 18.8% among eight samples that returned copper values in excess of 1%.
The 18.8% sample also returned 1.2ppm gold, 77ppm silver, 0.17% zinc and 0.057% cobalt.
