As more emerging exploration companies and investors catch wind of this impressive mining jurisdiction, the Edmund Basin could become a hot spot for high-quality mineralization and commodities like precious and base metals.
Australia is often known for sunny skies and big waves across its golden coast. However, the country has always been an understated gem in mining for some of the world’s most sought-after commodities.
Silver, gold and other high-demand base metals can be found across the continent, with high concentrations in the country’s Western regions.
One of these emerging prospects is the Edmund Basin in Western Australia. Underexplored and situated in a highly attractive jurisdiction for mining, the basin presents a potential for base and precious metal mineralization and widespread discoveries for early-movers who take advantage of Australia’s next big mining exploration site.
The mining history of the Edmund Basin
Australia stands as the world’s largest producer of lithium and a global producer of gold, iron ore, lead, zinc and nickel. According to the International Trade Administration, one-third of its mines are located in Western Australia, with over 350 currently in operation country-wide. As an up-and-coming mining jurisdiction, the Edmund Basin leverages high-quality mineralization and economic potential that has been demonstrated by many other geographical prospects surrounding the landform.
In the 1960s and 1970s, basement rocks of Western Australia's Gascoyne region and the overlying sedimentary rocks of the Edmund Basin and neighbouring Collier Basin were first systematically mapped by the Geological Survey of Western Australia. This program produced 1:250,000 scale maps, explanatory notes and a number of early reports outlining the protracted tectonic history of this part of the Orogen.
Other significant mappings and exploration campaigns have outlined the basin’s half-graben architecture, which was formed by the normal reactivation of older basement faults and sutures during the latter part of the Mangaroon Orogeny. According to the most recent profiling programs, the Edmund Basin and the Collier Basin have geological structures and rock formation styles that have been divided into six informal depositional packages, each defined by basal unconformities or major marine flooding surfaces.
Despite extensive mapping and geological surveying, the Edmund Basin remains underexplored and ready for discovery.
Mineral resources and major players in the Edmund Basin
The Edmund Basin contains a wide range of mineral occurrences — including supergene manganese, lead, gold and phosphate — many of which have been associated with major crustal-scale faults.
One of the most notable prospects in the region is Western Australia's largest strata-bound lead-gold-copper-silver deposit, the Abra base metals project. Owned by the major Australian mining player Galena Mining (ASX:G1A), the company’s flagship project is located in the Gascoyne region of the country. Leveraging the low-risk, Tier 1 jurisdiction status of the area, the celebrated Abra base metals project presents promising discovery potential.
Current reports estimate that Abra carries JORC mineral resource estimates of 16.7 million tonnes (Mt) at 8.5 percent lead and 24 grams per tonne (g/t) silver in the Indicated category and Inferred estimates at 24.4 Mt at 6.5 percent lead and 14 g/t silver.
Another player taking advantage of the Edmund Basin’s underexplored history and potential mineral resources is Todd River Resources (ASX:TRT). The Australia-based resource company’s Pingandy base metal project covers 895 square kilometres within the Edmund Basin. The company has received one licence and applied for three more. As an emerging mining company, Todd River is focused on outcropping, sub-cropping and continued exploration efforts to uncover the full extent of what the Edmund Basin has to offer.
Changing tides for Edmund Basin exploration
The uniquely varied geological and structural make-up of Edmund and the adjacent Collier Basin has posed some challenges in discovery and exploration in the past. Reactivated basement structures, basin inversion by reverse transpression and deformations all point to interesting mineralized profiles, but without the tools to explore these characteristics more extensively, the packages of the Edmund Basin remain relevantly untouched.
Luckily, advancements in mining technology, surveying and mapping have led to significant strides in discovery, development and exploration capabilities. Research and technology companies like the Australian Centre for Field Robotics have introduced advanced gradiometer technology, robotics, 3D imaging and automated drilling, which can be used to get to the core of underexplored mining prospects like the Edmund Basin. With mining companies and technology giants collaborating, the sky’s the limit for highly prospective regions like Western Australia and assets like the Abra base metals project.
As more emerging exploration companies and investors catch wind of this impressive mining jurisdiction, Edmund Basin could become a hot spot for high-quality mineralization and commodities like precious and base metals. Investors should look to first-movers like Galena Mining, which is already making strides to advance its positioning in Western Australia with its secondary Jillawarra manganese and gold properties, to see why Edmund Basin presents exploration opportunities unique to the Gold Coast.
The Edmund Basin in Western Australia sits amongst some of the world’s most abundant base and precious metal prospects and operating mines but remains underexplored. First-movers like Galena Mining and Todd River Resources demonstrate the early-mover advantage in exploring such a highly prospective region. With advancements in mining technology and good mapping and geological research already established in the area, investors and exploration companies could see very positive mining and exploration opportunities across the Edmund Basin.

Galena Mining (ASX: G1A) owns the Abra base metals project located in the Gascoyne region of Western Australia — home to one of the largest lead and silver deposits in the world set to produce the highest-grade, cleanest lead concentrate available globally. The company is capitalizing on its low-risk Tier 1 asset in a Tier 1 jurisdiction, strengthened by and leveraging partnerships with Japan's largest zinc and lead smelter, as well as with one of the top base metals trading firms in the world.
Galena recently completed a bankable feasibility study (BFS) for the development of a mine and processing facility with a 16 year lifespan producing high-value, high-grade lead-silver concentrate. Lead production is estimated at 95 kilotonnes per year while silver mining is projected to yield 805 kilo ounces annually. According to a pre-development capital expenditure estimate of AU$170 million, the BFS modelled a pre-tax net present value for Abra of AU$553 million, and an internal rate of return of 39 percent. Additionally, the project's excellent location, infrastructure, and low technical risk saw this mine named as the world's lowest cost primary lead mine by Wood Mackenzie, a leading mining research and consultancy group.
Galena's major partnerships include Toho Zinc (TSE: 5707), Japan's largest zinc and lead smelter and IXM SA, one of the world's top three base metals trading firms. Toho is providing AU$90 million project equity and has a long-term agreement to purchase 40 percent of Abra's production, while IXM has entered into a 10 year take-or-pay offtake contract to purchase the remainder.
The CEO of Galena Mining, Alex Molyneux, commented, "We have secured firm offtake arrangements for all of Abra's production with Tier 1 buyers and these arrangements reflect the premium value of Abra's high-grade concentrate product. The IXM arrangement in particular demonstrates a higher value over and above the assumptions used in the feasibility study."
The Abra project carries JORC Mineral Resource estimates of 16.7 million tonnes (Mt) at 8.5 percent lead and 24 g/t silver in the indicated category and 24.4 Mt at 6.5 percent lead and 14 g/t silver in the inferred category. This mineral resource estimate published in December 2019 was substantially upgraded following drilling during 2019. Despite being at the construction phase, Galena continues to actively drill to optimise Abra. As of late 2020, there are three drill rigs operating at Abra drilling 1,400 to 1,800 cumulative metres per week. The lead-silver orebody remains open in multiple directions and there have been exciting copper and gold intersections where mineralisation remains open at depth.
All permits for the Abra project have been obtained from the appropriate Western Australian regulatory bodies. The project is also subject to an existing land use and heritage agreement with the Jidi Jidi Aboriginal Corporation. The Abra property is well-serviced by public roads and highways, and all the necessary infrastructure has been developed to transport lead-sulphide concentrates to the Port of Geraldton, Abra's primary export port.
The first tranches of equity investment from Toho have been used to undertake initial construction activities at Abra. This means the project now has a mined boxcut, production water facilities, the first module of its permanent accommodation village and various completed site infrastructure. It is "shovel ready" for the commencement of plant construction and deployment of the mining contractor.
The company's management team brings decades of experience in the mining and base metals industry and has a proven track record of success throughout all stages of an exploration, from development to production. Both CEO Alexander Molyneux and CFO Craig Barnes previously worked for Paladin Energy (ASX: PDN), a publicly traded uranium production company that operates two mines in Namibia and Malawi.
Taurus Fund Management, one of the world's largest investment management firms, has provided the project with US$110 million in project financing debt. Galena's CEO Molyneux commented, "The US$110 million of debt funding completes an efficient and fulsome funding package to bring the outstanding Abra base and precious metals project to fruition in a way that provides robust shareholder returns."
The Abra Base Metals Project is located in the Gascoyne region of Western Australia, approximately 110 kilometres from the DeGrussa copper mine owned by Sandfire Resources (ASX: SFR).
Bankable Feasibility Study
Galena has recently completed a bankable feasibility study (BFS) for the development of a mine and processing facility with a 16 year lifespan producing high-value, high-grade lead-silver concentrate. Lead production is estimated at 95 kilotons per year while silver mining is projected to yield 805 kilo ounces annually.
According to a pre-development capital expenditure estimate of AU$170 million, the BFS modelled a pre-tax net present value for Abra of AU$553 million, and an internal rate of return of 39 percent.
Ongoing Project Drilling
As of late 2020 there are three drill-rigs operating at Abra drilling 1,400 to 1,800 cumulative metres per week for infill and optimisation drilling.
Recently announced drilling results included the best high-grade lead-silver drill-hole ever at the project (hole AB147). It revealed that the mineable domain is approximately 30 metres closer to the surface than originally predicted. Significant intersections from AB147 included:
- 5 m at 9.6 percent lead and 34 g/t silver from 266.2 m
- 9 m at 7.3 percent lead and 20 g/t silver from 288.1 m
- 5 m at 15.1 percent lead and 22 g/t silver from 321.8 m
- 9 m at 17.1 percent lead and 26 g/t silver from 366.2 m
"We're astounded at the success of hole AB147 in targeting a potential 'metal rich' combination of grade and thickness on the northern part of the eastern limb of Abra's Indicated Resource area, which is shallow and close to the current plan for early decline infrastructure. We have added a number of follow-up holes around AB147 to the drilling program with the intention to bring this area into the early years of the mine plan as an optimisation," said Galena Mining's CEO and Managing Director Alex Molyneux.
The Abra project has received all major permits and approvals and has begun construction. The company plans to use the conventional underground mining method of long-hole open stoping with paste backfill. Shallow dipping areas will be mined using the room and pillar method. The processing plant will employ single-stage primary crushing and semi-autogenous grind million comminution to produce high-grade lead-silver concentrate.
Next steps for Galena include receiving another AU$60 million in investment tranches from Toho, hitting construction milestones and optimizing drilling results from a comprehensive drill program that was conducted in August. The company is also focused on active exploration of the Abra property to identify additional base and precious metals mineralization in the Edmund Basin.
The Jillawarra properties are located 20 to 80 km west of the Abra Base Metals Project within the Jillawarra sub-basin of Gascoyne, Western Australia. The Jillawarra sub-basin hosts several base metal resources, as well as manganese and gold prospects, which have been explored since the 1970s. The majority of the drilling performed on-site has investigated 100 to 200 meters below surface.
Galena has launched a continued exploration program that aims to identify additional mineralization of both base and precious metals. The primary prospective corridor lies within the fault between the Quartzite Well and the Lyons River, which extends east-west along the entire tenement package and indicates many of the same geological markers associated with the world-class Abra base metals project. Galena continues to target its Jillawarra assets through geophysics and an active drilling and exploration program.
