- Initial drilling focussed on extending mineralisation beyond the current resource envelope to the north and south for open pit mine development studies
- Strike length at Anthill increased from 150m to over 350m and remains open in all directions
- A 4,000m follow up program and 1,000m regional new discovery program has now commenced with further results expected in the current September Quarter
- An updated Mineral Resource for Anthill is expected in the December Quarter
Commenting on the results of the Anthill program, Intermin Managing Director Mr Jon Price said:
"These initial results from Anthill are now clearly demonstrating the potential scale and quality of the orebody that continues to grow with each drilling campaign and certainly justifies our belief that the Zuleika shear can deliver new large scale open cut and underground gold deposits."
"The Company will continue aggressive extension and new discovery drilling at Anthill and looks forward to releasing an updated resource and continuing mine development studies."
In February 2018, Intermin commenced a self-funded $4M, 55,000m drilling program across its 100% owned Kalgoorlie gold projects. The major drill program is focussed on new discoveries and resource extensions at the key Teal, Anthill, Binduli and Blister Dam gold projects.
Drilling at Anthill commenced in the June Quarter with 70 angled RC holes for approximately 10,000m now completed to an average depth of 140m and maximum depth of 200m. The drilling focussed initially on resource extensions to the north and south of the current resource envelope which contains a JORC 2012 Mineral Resource Estimate of 1.42Mt @ 1.72g/t Au for 78,000oz Au at a 1 g/t cut off grade(see Note 4 below).
The geology at Anthill is dominated by a variolitic basalt with lesser amounts of porphyry and ultramafic rocks observed. At least two mineralised trends are evident and add to the geological complexity at Anthill. The sequence sits within a synclinal structure. The gold mineralisation is pervasive and occurs in a number of settings, the most important being a quartz stock work or thin veins with carbonate-sericite-silica-sulphide alteration. Some of the gold is coarse and is easily visible in panned RC chips.
New high grade, mineralisation outside of the current resource envelope has now been discovered and is aligned with the dominant NW "Zuleika Shear" stratigraphy confirming drilling orientation and increasing strike length to the north and south by over 200m. Mineralisation remains open in all directions (see Figure 3 in link below).
To the north AHRC18001 (best result 2m @ 7.08g/t Au and 10m @ 1.11 g/t Au), AHRC18002 (best result 20m @ 1.62g/t Au and 10m @ 1.27g/t Au) and AHRC18004 (best result 15m @ 1.79g/t Au) all intersected significant mineralisation where historic holes were drilled at opposite angles or were drilled too shallow(see Note 5 below).
To the south, AHRC18068 (4m @ 7.65g/t Au), AHRC18057 (best result 4m @ 15.5g/t Au) and AHRC18069 (best result 16m @ 1.32g/t Au and 24m @ 1.28g/t Au) cover an additional 150m strike length(see Note 5 below). There is no drilling to the south of these intercepts and further step out drilling has commenced.
AHRC18017 (81m @ 1.48g/t Au) and AHRC18018 (best result 26m @ 2.96g/t Au) (see Note 5 below) were step out holes in the central core area of Anthill where high grade ore is consistently found to about 200m depth. The impressive 81m width on AHRC1801 is found within a deep zone of stockwork ore. Low grade mineralisation was noted on the adjacent sections (at >200m depth) which suggests that this stockwork emplacement is also possibly controlled by a SW/NE structure.
Cross sections (4 x 20m) in this area are shown in figures 4-7(see link below). They show a series of stacked lodes variably dipping to the north east.
Another step out hole AHRC18010 has been drilled directly behind AHRC18018 with results expected in the current September Quarter.
To the west of Anthill, several holes discovered up-dip mineralisation from one of the deeper (stacked) low grade lodes as defined by mostly historic drilling. AHRC18019 (best result 12m @ 1.17 g/t Au) and AHRC18023 (best result 5m @ 4.55 g/t Au and 9m @ 1.08 g/t Au)(see Note 5 below). Further drilling to the west is planned.
Given the excellent results from the initial drilling, Intermin plans to complete a further 4,000m of resource extension drilling with the aim of extending the strike length further to grow the mineralised envelope ahead of a resource update and open pit optimisation studies.
In addition, over 1,000m of drilling has commenced on high priority new discovery targets including Fire Ant (see Figure 2 in link below) testing for repeat structures along the Zuleika shear zone.
Further assay results are expected in the current September Quarter, an updated Mineral Resource estimate in the December Quarter and a development scoping study in the March Quarter 2019.
