Initial Air Core Drilling Program Completed at Black Range
Highlights
-
Initial air-core drilling program has now been completed with all samples shipped to the laboratory for analysis
-
First laboratory results expected by February 2022
-
Sulphide minerals have been visually observed in air-core drill chips[1]
-
Nebula Prospect - new VHMS target defined by strong hydrothermal alteration coincident with a chargeability anomaly and indications of formation during a pause in volcanic activity, evidenced by a narrow horizon of black shale
-
In a VHMS system pauses in volcanic activity can be important periods for the accumulation of metal sulphide deposits
-
The geological features observed in drilling correlated very well to the IP/Resistivity geophysics, giving the Company confidence in its drill targeting moving forward
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.
The initial program has now finished with 1,800 meters of air-core drilling having been completed, see Figure 1 below for locations. This is less than the initial plan predominantly due to encountering the harder sandstone at shallower depths and more broadly than had been anticipated. The drilling not completed in this program is expected to be completed as part of the CY2022 diamond drilling program planned to commence early in the new year.
Resource Base Executive Chairman and CEO, Shannon Green commented:
“This initial air-core drilling program has been a tremendous success. It was undertaken safely, ensured full protection of the environment and we enjoyed complete support of our surrounding landholders. This initial drilling has provided further insight into the geology and has set RBX up brilliantly for the upcoming diamond drilling program.”
1 The Company notes this is based on visual inspection only and the samples are yet to be assayed or analysed.

Air-Core Drilling Program
The geological features observed from the initial phase of air-core drilling in the Eclipse area of the Company’s Black Range Project are highly encouraging[2] . Drill traverses were planned to test various IP and Resistivity geophysical anomalies and gather bedrock geology data not possible to obtain at the ground surface due to locally transported soils and the younger Grampians sandstones which cover bedrock in some places.
A new prospect, the Nebula Prospect, has been defined over an IP anomaly approximately 800m in length situated some 750m East of the Eclipse Prospect.
The Nebula Prospect is hosted in a sequence of volcanic and sedimentary rocks indicating deposition in a sea floor environment at a time when the source volcanic system was experiencing an important transition from intermediate to felsic volcanic composition and a period when volcanism stopped and marine sediments were deposited, evidenced by a narrow horizon of black shale. Due to limited nature of shallow air-core drilling data it is not known exactly how these features fit together and their timing relative to each other, but there does appear such changes occurring over a distance of 100-200m across the prospect.
In a VHMS system pauses in volcanic activity can be important periods for the accumulation of metal sulphide deposits and mark prospective horizons which need to be tracked in ongoing exploration. As we have encountered what appears to be such a horizon and it is also the locus of intense hydrothermal alteration, potentially related to activity of hot fluids transporting metals up through the volcanic pile to the seafloor, this prospect is of great interest in our search for VHMS base metal deposits in the area. Any low-level base or precious metal geochemistry around this zone of alteration will further heighten the prospectivity of the Nebula Prospect, so assay results expected early next year are eagerly awaited.
Of the planned 4,000m air-core drilling, only 1,800m was completed as Grampians Sandstone cover in the western margin of the geophysical survey area proved to be too thick and hard for penetration with air-core drilling. These areas are planned to be investigated with diamond drilling early next year. Elsewhere on the project the air-core technique has proven to be very successful and cost effective for first-pass bedrock testing.
Exploration Program
As part of its aggressive exploration program, the Company is aiming to commence diamond drilling of deep bedrock targets in Q1 CY2022. 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 drilling 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.
