Alteration & Sulphides in Black Range Air Core Drilling
Highlights
-
Air-core drilling being undertaken to test geological and geochemical signatures of geophysical targets across the Eclipse Basin, which is known to host VHMS mineralisation with potential for porphyry mineralisation
-
A broad zone of strong hydrothermal alteration has been intersected on the Nebula Prospect, a chargeability anomaly of moderate strength tested by drill traverses, T11, T12, and T6 (Figure 1)
-
Sulphide minerals have been visually observed in air-core drill chips
-
The geological features observed in drilling are correlating very well to the IP/Resistivity geophysics, giving the Company confidence in its drill targeting moving forward
-
Drilling is expected to continue for approximately 1 more week, with first geochemical results expected to be available early in CY2022
Resource Base Limited ( ASX:RBX ) ( Resource Base or the Company ) is pleased to provide an update on progress of its initial air-core drilling program at its Black Range Project located in the well-known and highly prospective Stavely Volcanic corridor in North-West Victoria, which is prospective for copper, gold and zinc.
Resource Base Executive Chairman and CEO, Shannon Green commented:
“It is very exciting to see such positive geological indicators at such shallow depths and so early in the program. The correlation to the geophysics is also very exciting enabling us to target our drilling with confidence.”
Air-Core Drilling Program
An approximately 4,000m air-core drilling program is underway to test a series of geophysical targets generated by recent IP/Resistivity and Gravity geophysical surveys. This is a cost-effective reconnaissance drilling program, designed to narrow the focus prior to commencement of diamond drilling.

To date 1,265m have been drilled and the Company is pleased to report the following geological observations:
-
Broad zone of strong hydrothermal alteration has been intersected on the Nebula Prospect drill traverses, T11, T12, and T6 (Figure 1) which has not been drilled previously and is defined by a moderate chargeability anomaly
-
Sulphide minerals have been visually observed in drilling on Nebula Prospect. (The Company notes this is based solely on visual inspection and core is yet to be assayed or analysed)
-
The geological features observed in drilling are correlating very well to the IP/Resistivity geophysics, giving the Company confidence in its drill targeting moving forward

The air-core drilling program is aimed at confirming bedrock geology hidden below shallow transported cover and Grampians Sandstone units. It will also test for the presence of slight geochemical anomalies over geophysical targets. Indications of geochemical signatures interpreted to be associated with VHMS or Porphyry mineralisation will increase ranking of the geophysical target for deep bedrock diamond drilling early next year, see Figure 1 below.

Exploration Program
As part of its aggressive exploration program, the Company is aiming to commence diamond drilling of deep bedrock targets in Q1 2022. Final geophysical data modelling and geochemical analyses from the current round of shallow air-core drilling are required to prioritise targets for the deeper diamond drilling.
Air-core driling is planned to then continue to further target areas across the broader tenement following further geophysical programs.

About Resource Base Ltd
Resource Base Ltd (ASX:RBX) is an Australian based mineral exploration company focused on the development of highly prospective exploration projects with demonstrated potential for scalable discoveries.
Black Range Project
The Black Range Project (124km[2] ) in Victoria’s premier porphyry and VHMS target district, the Mount Stavely Volcanic Complex (MSVC) in Western Victoria, captures three fault-bound segments of the MSVC volcanics with a combined strike length of approximately 55 kilometres. The Project includes the advanced Eclipse prospect which is prospective for copper, gold and zinc.
The Mount Stavely Volcanic Complex is considered an analogue of the Mt Read Volcanics in Tasmania, which is host to a number of world-class VHMS deposits (Rosebery, Hellyer, Que River), the giant Mt Lyell Cu-Au deposit, and the Henty Au deposit.
Numerous other targets, including Anomaly F, Honeysuckle, Anomaly K and Mt Bepcha are associated with MSVC rocks across the tenement but have seen little work to date.
Petrological studies indicate that important VHMS style hydrothermal alteration and is well developed on the Eclipse prospect. Resource Base will utilise systematic geophysics, drilling and geochemical analyses combined with petrological and hyperspectral SWIR alteration mapping to vector towards zones with high mineralisation potential as identified from comparison with known VHMS deposits in the Mt Read Volcanics and around the world.
Mitre Hill Project
On 27 September 2021, the Company announced it had entered a binding term sheet for the acquisition of the Mitre Hill Project (1380km[2] ), which contains five strategic tenement applications over ground located within the Murray Basin across Victoria and South Australia, prospective for ionic clay hosted Rare Earth Element (REE) deposits.
The Applications are located in the Murray Basin on the South Australian and Victorian state Border near the towns of Naracoorte, Penola and Edenhope. The largest and most prospective Application, ELA 2021/00059, runs approximately in a line, covering over 40km of strike length, from the towns of Naracoorte and Penola in South Australia. The main economic target is ionic clay hosted Rare Earth deposits, with possible economic concentrations of Heavy Rare Earths considered strategically important given global supply modelling.
The Applications are located over the transition from the concluding phases of the Loxton - Parilla strandlines to the more broadly spaced Bridgewater formation in South Australia and Victoria. A significant archive of historical exploration data has been acquired by the Company, including drilling results, numerous government studies and minor private exploration.
