THE INSIDE STORY: Aruma Resources (ASX: AAJ) has made considerable progress in rapid time as it targets large scale sediment- hosted gold deposits throughout its Eastern Goldfields project area in Western Australia.
Aruma Resources’ 100 per cent-owned Slate Dam project is located 40 kilometres from the home of WA gold mining, Kalgoorlie.
The company recently expanded the Slate Dam project area and consolidated ground holding via the 100 per cent acquisition of the Trojan gold project (ML25/104) from Westgold Resources (ASX: WGX).
To the north, Aruma has the Beowulf gold project, which it pegged in 2017, covering 490 square kilometres of gold prospective greenstone sediments.
The company’s present focus is Slate Dam, which it believes has comparisons to the world class Invincible gold deposit, being mined by global gold major Gold Fields at its nearby St Ives operation.
Determined to increase the proven gold mineralisation footprint at Slate Dam, Aruma has had drill rigs constantly spinning on the project since late last year, completing 63 RC holes for 6,774 metres in two phases of drilling which have produced a raft of encouraging results.
A Phase 2 drilling program was undertaken early this year at Slate Dam consisting 23 holes of reverse circulation (RC) drilling for a total of 2,778 metres to follow up results achieved from the first phase of drilling that defined what are interpreted as two major, tabular 20m thick shoots dipping 30 degrees to the west.
The Phase 2 drilling program did what it was asked in expanding the footprint of the gold mineralised system at the Slate Dam Project.
The drilling also confirmed the sediment hosted gold mineralised shoots that had been delineated by the Phase 1 drilling.
Assays showed the drilling to have encountered multiple intersections of anomalous gold mineralisation, with 12 of the 23 holes drilled intersecting gold mineralisation.
Aruma’s second phase program expanded the Slate Dam gold mineralised system to a total distance of at least four kilometres (from the north-west to the south east) – via the delineation a new gold shoot, christened S2.

“We took a great deal of encouragement from that second Phase of drilling at Slate Dam,” Aruma Resources managing director Peter Schwann told The Resources Roadhouse.
“While we continue to pursue further higher-grade mineralisation and the source of what we believe to be a significant new gold system at Slate Dam, our first two drill programs completed in the space of just six months, have taken the project from concept to validation and increased its potential to host significant sediment-hosted gold deposits.
“Importantly, the drilling continued to intersect gold mineralisation over a large portion of our initial target area, providing confidence to immediately commence a next round of drilling to look for extensions and repetitions, plus higher-grade zones.”
Aruma wasted little time getting back out on the ground and on 1 June kicked of its third phase of drilling at Slate Dam.
During this round, Aruma targeted the completion of approximately 3,000m of RC drilling across a total of 25 holes up to depths of 150m.
Recent Phase 3 drilling targeted priority areas to the north and south of the currently drill defined shoots at Slate Dam designed to extend the current gold mineralised system while hoping to identify repetitions of the mineralised system to the east and to the west of the drill defined area.
At the time of writing, Aruma had received assay results from the first eight holes (holes SDRC64 to 71) of this program, which continued strengthen the company’s exploration model for the project to host sediment-hosted gold deposits.
The Phase 3 drilling intersected widespread shallow gold mineralisation with seven out of the eight holes assayed intersecting anomalous gold mineralisation.
Of importance was that the drilling discovered a new gold trend to the east of the current drill defined area at Slate Dam, with a highlight intersection of 6m at 2.43g/t gold from 15m returned from within a broader zone of 15m at 1.1g/t gold (in hole SDRC68).
“The first assay results in the Phase 3 drilling returned multiple broad zones of gold mineralisation plus further strong grades,” Schwann said.
“The significant gold intersection in hole SDRC68 is of substantial importance as it duplicates the similar intersection of 7 metres at 2.1 grams per tonne gold in the nearby drill hole SDRC20 reported in our first phase of drilling.
“This is an important result, as it confirmed the presence of gold mineralisation and increasing grades to the east at the project, which was a key objective of this phase of drilling.
“We will now seek to extend these two near surface gold zones along strike and look for more repetitions to the east in the remaining holes in the Phase 3 program.”
Aruma’s drilling to date at Slate Dam has focused on a major, high tenor gold anomaly measuring 200ppb gold and covering an area of seven square kilometres, in the north of the project – and it will continue to prove up the gold system at this target.
In parallel, the company is about to embark on a detailed project-wide targeting program over the entire 255 square kilometre Slate Dam project area, and the Beowulf project, to define the next batch of priority drill targets.
“This is hugely exciting for the company, Schwann enthused.
“To date we have drilled one priority target at Slate Dam, which has resulted in the discovery of a significant sediment-hosted gold system.
“Now we are now expanding our focus to take in the in the entire 750 square kilometres of tenements at Slate Dam and Beowulf, with the aim of delivering multiple, new high priority drill targets.”
This work is already underway with a comprehensive data base for all the projects currently being constructed, utilising the extensive amount of available data on the projects.
Then the company will then apply magnetic surveys and aerial electromagnetic (EM) programs to generate and rank priority targets for the next phases of drilling.
Current timelines have the company ready to drill to first of the newly ranked targets in the final quarter of calendar 2018.
As part of this project-wide approach, Aruma may also pursue the opportunity to expand the known resources at Triton, which currently stand at 2.8 million tonnes at 1.61g/t gold for 144,800 ounces of gold (at a 0.7g/t cut‐off).
Schwann brings a keen sense of purpose and intent to the work ahead of the company.
“We have two outstanding greenstone belt projects – Slate Dam and Beowulf – in a highly sort after mineral district in the Eastern Goldfields, where the likes of AngloGold Ashanti, Northern Star and Silver Lake all have operations,” he explains.
“Our initial targeted drilling has delivered immediate success and we will continue advance that as a core priority, and that along with the opportunity to discover and develop district scale gold deposits makes the outlook for Aruma very exciting.
“If you look at Gold Fields Invincible Deposit, it was taken from discovery holes being drilled in 2012 to now being a world class gold deposit, which hosts more than three million ounces of gold.
“We believe the potential discovery upside for us is enormous, and we have a clear focus and plan in place to unlock this.”
