The Murrin Murrin project area comprises 14 PLs and one small ML situated approximately 45km east of Leonora in the Mt Morgan’s District of the Mt Margaret Mineral Field. It is approximately 15km south of the Murrin Murrin lateritic Ni-Co Mine and lies within a 15-20km radius of Kin’s Mt Flora, Randwick and Redcastle Project areas.
The Company’s Murrin Murrin leases form a contiguous package which is located adjacent to the historic Murrin Murrin gold mining centre and the former Anaconda, Rio Tinto and Nangeroo base metal mines as well as being close to several of Glencore International PLS’s nickel-cobalt laterite resources.

The tenements cover a section of the Murrin Murrin Greenstone Belt and overlie a suite of NNE trending tholeiitic mafic volcanics, dolerites and minor sedimentary units, including banded iron formation (“BIF”) and chert. Primary gold mineralisation generally occurs as “stacked”, shallowly dipping mineralised quartz veins associated with thrust faulting.
Metal detecting and prospecting by individuals and small syndicates has been widespread throughout the district since the early 1980s and a number of large alluvial gold patches have been discovered during this time. Many historic gold workings occur throughout KIN’s various leases.
Previous test-drilling has identified numerous gold anomalies in close proximity to this mineralisation and these represent ‘walk up’ drill targets. Other prime gold targets occur at the intersection of major faults and shear zones.
During the year three Reverse Circulation (RC) drilling campaigns were conducted at Murrin Murrin (P39/5179) for an advance of 2,909m. The drill programmes intercepted supergene and primary gold intersections. The down hole geology displayed quartz veining, occasionally carbonated, in mafic gabbro associated with regional thrust faults. Sulphides, dominantly pyrite, are associated with the host rock and low percentages of sulphides were observed associated with the quartz veining.
The most significant primary gold intersection (MM13RC013) is positioned beneath weathered clayey regolith (35-40m to deep) in an area of no outcrop; however the unit is interpreted to strike north-easterly and dip south easterly. Best assay results are tabled below (>1g/t Au).
Significant intersections include:
•MM13RC013 – 31m @ 4.29 g/t Au (64-95m) including 2m @ 34.23g/t Au (87-89m)
•MM14RC022 – 23m @ 1.00 g/t Au (13-36m)
•MM14RC021 – 11m @ 2.56 g/t Au (20-31m)
•MM14RC023 – 4m @ 4.62 g/t Au (84-88m)
•MM14RC027 – 10m @ 1.31 g/t Au (30-40m)
•MM14RC028 – 9m @ 1.90 g/t Au (33-42m)
The drilling of the scissor hole MM14RC023, was aimed at following up on previous significant intersections including the high grade intersection encountered in MM13RC013, which returned 2m @ 34.23g/t Au from 87m down-hole (see Figure 2).
Drill hole MM14RC023 intersected a mineralised ore zone, interpreted to represent the high grade shoot encountered in MM13RC013; however the geometry and orientation of the mineralised envelope intersected in MM13RC017 and MM13RC013 has not yet been fully determined. Originally, 4m composite samples were collected and assayed; results considered anomalous were analysed via fire assay at 1m intervals, significant results are presented in Table 1.
