For | Aruma Resources Limited (ASX: AAJ) (Aruma or the Company) is pleased |
to provide the following report on its activities for the quarter ending 30 June 2022.
Aruma has a portfolio of four prospective gold projects in Western Australia. This includes the Carter Well Project, which was recently added to the portfolio (ASX announcement, 6 July 2022). All are strategically located in active gold domains. The Company also has a prospective Lithium-Tantalum-Rubidium project in the lithium corridor of south-east WA (Figure 1).

Aruma enjoyed another active quarter. A diamond drilling program was completed at the Salmon Gums Gold Project which followed up bonanza-grade gold results reported at the Project in the previous quarter. Significant lithium grades and high-grade rubidium were reported from the Company's maiden drilling program at the Mt Deans Lithium Project, and this was followed up by a successful rock chip sampling program, as a next step in the systematic exploration of the Project.
In line with the Company project policy, Aruma relinquished almost half of the Saltwater project after reviewing prospectivity. Aruma also added the Carter Well Gold Project in the Murchison region of WA to its project portfolio at the end of the quarter.
Negotiations with the traditional owners have achieved a scheduled statutory heritage survey in August allowing a maiden drilling program to be carried out at the Melrose Gold Project in the Pilbara region of WA.
Corporately, the Company is in a strong position with a cash balance at quarter's end of $4.6 million.

Mt Deans Lithium-Rubidium Project, Norseman, WA
The Mt Deans Project is situated in the Mt Deans pegmatite field, within the Eastern Goldfields Terrane of the Yilgarn Craton, approximately 170 kilometres south of the major regional centre of Kalgoorlie and approximately 10 kilometres south of the mining town of Norseman.
The Project sits within the lithium corridor in south-east WA, which hosts multiple significant hard-rock lithium projects. It is interpreted to sit within the same host rocks and structures as the significant nearby Mt Marion, Bald Hill and Buldania Lithium Projects.
During the quarter, Aruma reported results from its maiden, 1,156 metres, reverse circulation (RC) drilling program (ASX announcement, 21 April 2022). Eight holes were completed in the first phase of the program and delivered highly positive results including high-grade rubidium.
Drilling intersected lithium grades of up to 1.14% Li2O (lithium oxide) within a wide zone of lithium, all within a near-surface 25 metre thick, vertical body of solid pegmatite, from a depth of just 17 metres. Results include;
1m @ 1.14% Li2O at 36m in hole MDRC6 within a wider zone of
- 10m @ 0.62% Li2O and 0.57% Rb2O from 22m and
- 7m @ 0.76% Li2O and 0.69% Rb2O from 31m and
- 3m @ 0.96% Li2O and 0.83% Rb2O from 34m
The first phase of drilling defined an interpreted strike length of at least 1,500 metres, which remains open at both ends (Figure 3).
Drilling targeted the priority Mt Deans 'main section' and defined a thick vertical pegmatite, with pegmatite intersected in every hole (Figures 2 and 3). The program returned more than a dozen intersections grading higher than 0.5% Li2O from the eight holes drilled to date, and also returned high-grade rubidium, grading up to 1.05% Rb2O (Rubidium Oxide), with elevated tin, tantalum and cesium.
Drilling Intersects High-Grade Rubidium
Rubidium is a high-value technology mineral typically found in hard rock pegmatites. It has multiple uses and applications, including in solar panels, fibre optic cables, GPS systems and night vision equipment, as well as sodium-ion batteries.
The rubidium results from the completed drilling exhibit a strong relationship with the lithium assay results (as well as the rare earth elements) from the drilling and has the potential to add significant value to the Project - and will become a core focus, in parallel with lithium, in future exploration at Mt Deans.

Rock Chip Sampling Program Returns High-Grade Lithium and Rubidium
Aruma completed a successful strike-extension rock chip program along the strike of the main pegmatite at Mt Deans (ASX announcement, 30 May 2022). The results delivered high-grade lithium and rubidium grades, including lithium of up to 1.96% Li2O (lithium oxide) and rubidium of up to 1.42% Rb2O (rubidium oxide), plus cesium values up to 1,550ppm, from a surface rock chip sampling program targeting (Table 1).
A total of 11 rock chip samples along a 500m strike were taken in the program. It was designed to test for strike extensions to the interpreted pegmatite zone at Mt Deans, which has a strike length of at least 1,500m, and help refine targets for the second phase of the maiden drilling program.
The sampling results indicate a strong positive relationship with Aruma's lithium and rubidium drilling results at Mt Deans. This is further supported by results from previous rock chip sampling which also delivered high-grade results, of up to 2.1% Li2O (ASX announcement, 24 March 2021).
Aruma has now booked a specialised RC rig to complete the remaining 1,800 metres across 12 holes in the maiden drilling program at Mt Deans as a priority.

Salmon Gums Gold Project
The Salmon Gums Project (EL63/2037, EL63/2122) covers a total area of 222km2, and is located 200km south of Kalgoorlie, and 60km south of the mining town of Norseman (Figure 1). The Project is situated 30km south and directly along strike in the same stratigraphy as Pantoro Limited's (ASX: PNR) rapidly expanding high grade Scotia Gold Project.
