Everest spins drill bit in search for gold northeast of Southern Cross
Everest Metals has started spinning the drill bit at its Mt Dimer Taipan project in the hunt for further gold and silver at the site, 150 kilometres northwest of Kalgoorlie.
The reverse circulation drilling program will test four high-priority targets identified through advanced satellite imagery and geochemical anomalies. Targets were defined from the integration of interpreted geochemical anomalies and alteration zones outlined by high-resolution satellite imagery.
The company aims to expand the existing mineralisation at Mt Dimer Taipan, which remains open to the south and at depth, by combining historical data with advanced exploration methods.
The project contains an existing mineral resource of 722,000 tonnes grading 2.1 grams per tonne (g/t) gold for 48,545 ounces.
Management submitted a mining proposal and mine closure plan for the project last August to the Western Australian Department of Energy, Mines, Industry Regulation and Safety and anticipates receiving approval within the next two months.
Everest has completed extensive work on its mining proposal, including a geotechnical study, hydrogeological modelling, baseline environmental study and flora and fauna surveys.
The department requested further information in January and Everest submitted updated proposal and closure plans on March 12.
The company also applied for a 45-million-litres-per-annum groundwater licence and plans to drill a water borehole to a depth of 120m to support its upcoming activities and future mining operations at site.
When the mining proposal is approved, Everest expects to launch into mining activities.
Mt Dimer Taipan's mining proposal involves a cutback of the existing pit to extract ore laterally and from the pit's base. Everest plans to process the ore nearby.
Given today's sky-high gold price, the company believes it has a terrific opportunity to charge into the task of turning Mt Dimer Taipan into a profitable mining operation, utilising a toll-treatment agreement with one of the nearby mills. Negotiations with nearby plant operators are ongoing.
Everest completed a geochemical soil sampling program in 2021 to verify historical geochemical results, structures, shear zones and lithological contacts previously mapped by the Geological Survey of WA, which were interpreted from magnetic inferred structures.
The program outlined three distinct geochemical anomalies in part of the company's ground, returning assay values up to 430 parts per billion (ppb) gold and 420 parts per million arsenic. Four anomalous zones with gold values exceeding 100ppb were identified and two are considered higher-priority targets for testing.
Everest's recently processed satellite data identified iron oxide and alteration mineral signatures relevant to orogenic gold and banded-iron formation-style exploration. Analysis techniques were applied to identify hydrothermal alteration minerals linked to orogenic gold systems.
An alteration mineral intensity map was generated, highlighting alteration zones in the central part of the licence area, with characteristics similar to those at Mt Dimer Taipan and nearby gold mining districts.
Everest acquired Mt Dimer Taipan in 2020, along with an additional exploration tenement to the west of the project. A range of rotary air-blast drilling, reverse circulation and diamond drilling identified mineralisation at the project.
Former owner Taipan Resources mined the project in the mid-1990s, hauling out 84,000t at about 4.61g/t for 5933 ounces of gold. Several small players later leached the stockpiles for gold and silver, with moderate success.
With gold and silver prices remaining strong, Everest will be hoping for a mountain of positive news from this drilling program.

At The Track: Sydney racing scores with Everest slot deal
The Australian Turf Club's decision to lease their Everest slot to Hong Kong Jockey Club for at least two years is a coup for Sydney racing. The deal ensures that barring injury or some unforeseen circumstance, the world's number one-ranked racehorse, Hong Kong's superstar sprinter Ka Ying Rising, will contest the Group 1 $20 million The TAB Everest at Royal Randwick on October 18. Hall of Fame trainer David Hayes has also indicated Ka Ying Rising will stay in Sydney for the $3 million Russell Balding Stakes (1300m) at Rosehill Gardens two weeks later. Racenet iQ members get full access to our Pro Tips service, where Greg and our team of professional punters provide daily tips with fully transparent return on investment statistics. SUBSCRIBE NOW and start punting like a pro! ATC will benefit financially from the World Pool, the international commingling parimutuel betting operation which is managed by HKJC and will be available to punters on Everest Day. There is also speculation the World Pool will be added to more Sydney race meetings next season, most notably Golden Slipper Day which boasts five Group 1 races. HKJC executive director of racing, Andrew Harding, told Hong Kong media the club has secured the ATC's Everest slot for two years with an option to extend. 'For this year, the club will use the slot to enable Ka Ying Rising to take part in The Everest,'' Harding told South China Morning Post. 'In future years, we will use the slot to either facilitate a Hong Kong horse running or to target Australian or New Zealand sprinters to come onto the Hong Kong International races after The Everest.'' ■ ■ ■ ■ ■ Ka Ying Rising joins Briasa (slot holders Max Whitby, Neil Werrett and Col Madden) and Private Harry (Yulong) as confirmed Everest starters. Sunshine In Paris, owned by Everest slot-holder John Camilleri of Fairway Thoroughbreds, is also being set for the big race. This leaves eight slots remaining and competition for an Everest start will be fierce – but not everyone is happy. A leading Sydney trainer contacted At The Track incensed that ATC had not used their slot for an 'ATC trained horse'. 'Surely that's the idea of a slot,'' the trainer said. 'That's like Wayne Bennett picking a player from another club for the grand final. What a disgrace.'' The trainer's disappointment is understandable but the financial benefits to ATC for leasing their slot HKJC and having the World Pool alignment on Everest Day is considerable, and the club wants the best possible field for the world's richest turf race so securing Ka Ying Rising was the number one priority. ■ ■ ■ ■ ■ Is Coolmore's three-year-old filly Minnie Hauk, winner of the English Oaks yesterday, the most valuable potential broodmare still racing? Minnie Hauk, a daughter of English superhorse Frankel and closely related on her dam's side to another champion, Kingman, was purchased for about $A4 million as a yearling at the Goffs Orby Sale and her Oaks win means she is now a priceless broodmare once her racing days are over. The regally-bred Minnie Hauk gave Irish training genius Aidan O'Brien his 11th Oaks win when she defeated her stablemate Whirl. ■ ■ ■ ■ ■ The US triple crown isn't on the line but the final leg of the famous series, the Belmont Stakes, takes on special significance with the return clash of Godolphin's Sovereignty and Coolmore's Journalism in New York on Sunday morning. Sovereignty won an epic Kentucky Derby from Journalism last month but missed the second leg, the Preakness Stakes. In his absence, Journalism scored an incredible Preakness win and is early favourite with TAB Fixed Odds for the Belmont at $2.60 with Sovereignty pressing at $2.80.

Everest ticks off extraction study to start Aussie rubidium industry
Everest Metals and Edith Cowan University (ECU) have achieved 97 per cent rubidium extraction in a joint engineering scoping study for Everest's Mt Edon project in Western Australia. The study is a key step in Everest's plans to pioneer a new rubidium industry in Australia. Everest plans to inject Australia onto the world rubidium stage by unlocking the nation's entry into a new and valuable critical mineral processing industry. The engineering study was completed at ECU's Mineral Recovery Research Centre, which Everest asked to help develop an innovative rubidium extraction process. The direct extraction process aims to extract the critical mineral in a more cost-effective and environmentally friendly manner from ore mined at the company's Mt Edon critical mineral project in WA's Mid West region. Demand for the rare mineral used in high-tech industries, such as defence, aerospace and communications, is expected to lift significantly. Research by global market research company Market Research Future projects global market usage to grow from US$4.46 billion (A$6.91B) in 2023 to US$7.2B by 2032 using a compound annual growth rate of 5.48 per cent. The study achieved exceptional results from phase three beneficiation and leaching testwork, which produced the outstanding 97 per cent recovery rate for rubidium oxide from Mt Edon's primary ore. Everest has elected to lock in a standard patent to protect its new-age technology, having realised the effectiveness of its extraction process. It jumped on a provisional patent for the process earlier this year. The company says the results confirm the project's potential commercial and technical viability, based on its plans for a processing plant capable of producing 750-1000 tonnes per annum rubidium chloride. Further studies are required to nail down an optimised process. Management believes the project can prosper from broad geopolitical initiatives, such as United States President Donald Trump's April executive order calling for an investigation into the national security risks associated with its dependence on imported processed critical minerals. The executive order outlines an urgent need to develop transparent, secure and US-aligned supply chains for required critical minerals. Rubidium has many high-technology applications and is listed as one of 35 critical minerals by several countries, including the US and Japan. Everest sees the current price of rubidium carbonate, near US$1170 per kilogram, as providing the project with strong potential to develop into a profitable operation. Downstream applications are fuelling rapid growth with an increase in demand for rubidium salts. With the engineering study complete, Everest has work underway to increase the efficiency of its extraction technology and reduce costs. During testwork, data from samples indicated the beneficiation process enhanced rubidium liberation and therefore its availability for downstream extraction, removing gangue minerals. Beneficiation led to higher leaching efficiency and improved outcomes, resulting in the 97 per cent recovery levels. The innovative extraction method is part of a process involving mining, beneficiation to concentrate the rubidium-bearing minerals, followed by roasting-leaching-crystallisation to produce rubidium chloride. Further analysis is required to evaluate the technical and economic risks for scalability and operational stability. The company plans to run additional bench-scale and pilot-scale testwork to validate its process before building a full-scale plant. Everest has an agreement with the CSIRO to enhance its understanding of rubidium, caesium and lithium mineralogy. The increased knowledge of the critical minerals is expected to improve the company's processing methods and overall recovery rates. Everest applied to the Minerals Research Institute of WA for funding under its METS Innovation program. The application sought matched funding to support upcoming metallurgical and purification testwork. The company expects to receive word on its application this month. It is also exploring grant funding opportunities and potential future funding options through domestic and international critical mineral initiatives to help scale up to a pilot plant next year. Mt Edon is 420 kilometres northeast of Perth and 5km southwest of the State's former gold rush settlement of Paynes Find. The project has an inferred mineral resource of 3.6 million tonnes grading 0.22 per cent rubidium oxide and 0.07 per cent lithium oxide. Management says the resource contains a world-class component of 1.3Mt at 0.33 per cent rubidium oxide and 0.07 per cent lithium oxide. The high-grade zone contains 56 per cent of the total contained rubidium tonnes at Mt Edon, which has 7900t of the rare critical mineral. Everest says its initial resource is based on drilling along 400 metres of strike within a 1.2km-long pegmatite corridor on a 192.4-hectare granted mining lease. Drilling was conducted to a vertical depth of 140m below surface, with 61 reverse circulation drill holes plunged in over 2779m to determine the estimated resource. Everest holds a 51 per cent stake in Mt Edon with the potential to take over the entire operation in a joint venture farm-in agreement with private company Entelechy Resources. The company is aiming big: It is looking to develop a fledgling industry locally, supply a growing market globally, and support the nation's defence needs with a reliable rubidium supply.
