China discovers world's deepest sandstone-type industrial uranium mineralisation
China has discovered the world's deepest sandstone-type industrial uranium mineralisation at a depth of 1,820 metres in the Tarim Basin, Xinjiang Uygur Autonomous Region, according to the China Atomic Energy Authority (CAEA). This discovery sets a new global record for the deepest sandstone-type industrial uranium mineralisation ever found, according to People's Daily Online. Uranium exploration aims to locate and identify uranium deposits of industrial value, assessing their resource potential and development prospects. Industrial uranium mineralisation serves as a direct and reliable indicator for discovering industrial uranium deposits. The mineralisation discovered this time represents China's first finding of thick industrial uranium mineralisation within the reddish, variegated strata of a previously unexplored area in the heart of the desert within the Tarim Basin. It fills a gap in mineral prospecting within China's largest desert-covered region. The discovery plays an exemplary and leading role in sandstone uranium exploration and will significantly enhance China's capability and expertise in uranium resource exploration in desert regions, said the CAEA.

Barry FitzGerald: At Sky Metals you buy one tin project, get one free
'Garimpeiro' columnist Barry FitzGerald has covered the resources industry for 35 years. Now he's sharing the benefits of his experience with Stockhead readers. There's been a known massive slug of tin-dominant polymetallic mineralisation sitting out the back of Bourke in north-west NSW crying out for some attention for more than 50 years. That and a metallurgical breakthrough. It's called Doradilla and its owner since 2019, the Norm Seckold-chaired Sky Metals (ASX:SKY), looks to have cracked the code to unlocking the project's big-time potential thanks to current day tin flotation processing technology. Garimpeiro last took a look at Sky in August last year when it was a 3.2c stock for a market cap of $18.8 million. It has since moved up to 7c for a market cap of $49.7 million, a valuation comfortably underpinned by its advanced Tallebung tin project in central NSW. Sky is coming to an end of a four-month drilling program at Tallebung and results to date suggest there will be a big increase in the last inferred and indicated resource estimate of 15.6Mt grading 0.15% tin for 23,000t contained, once all the data is in. It shouldn't take long after that to give the market a feel for its production capability. Given Tallebung is particularly amendable to ore sorting to bump its grade by a factor of five times, the project is likely to be shown to be capable of making Sky's current market many times over in years to come. It's early days at Doradilla in comparison but Sky's metallurgical breakthrough could well see it emerge as a multi-decade tin producer, possibly with rare earths and other metals as part of deal. The lowdown on Doradilla Sitting in semi-arid goat country, Doradilla was first drilled in the 1970s. It's part of a 17km linear skarn which hosts the Doradilla, Midway and 3KEL deposits – the famous (in exploration circles) DMK Line. Big name tin miners past and present (including Renison, Aberfoyle, North Ltd and YTC Resources) had a crack at unlocking the DMK Line but had basically packed up and left by the 1980s when it was realised that simple gravity separation would not work. Sky managing director Ollie Davies takes up the story: 'We've always been aware of the potential for the Doradilla project to host an extensive tin system, however our ability to progress this asset has been hindered by our ability to unlock the tin through a viable metallurgical processing route.' 'Now, through the application of a combination of conventional gravity, magnetic and new flotation process steps, we have achieved economic recoveries of up to 78% tin.' 'This is an exciting and very significant breakthrough which transforms the potential and outlook for this project. While our primary focus remains squarely on the Tallebung tin Project, where we are in the midst of a major resource expansion drilling campaign, Doradilla is clearly shaping up as a sizeable and very attractive pipeline development asset.' Drawing on Doradilla's historical database and its own work, and in light of the metallurgical success, Sky has been able to report a compliant 'Exploration Target' of 10-15 million tonnes grading 0.32-0.42% tin for 32,000-63,000t of contained metal. The target is based on a 2.5km section of Doradilla and there is another 2.5km of strike length on either side. So potentially at least, an already big exploration target could eventually be tripled. The Doradilla breakthrough comes as the tin market remains as strong as you like. The metal was last quoted on LME at $US33,312/t (three month). So it remains more than three times the copper price. The price jumps around depending on production news from operations in, shall we say, fraught locations around the world. Demand is super strong thanks to growing uses in solar panels and all the circuitry that needs to be connected to deliver AI. New mine developments in desirable locations are few and far between and like other critical metals, China has what could be a called an unhealthy grip on the market. Sky's share price did not move on Monday when the metallurgical breakthrough was revealed. Fair enough, the market is being cautious. But given Garimpeiro's suggestion that the company's market cap is more than covered by the Tallebung project, it seems likely it won't be long before the market begins to reward Sky for unlocking Doradilla.

HGO eyes expanded Kanmantoo copper resource
HGO spots copper outside of existing Kanmantoo mine resource Deepest drill hole intersected 2.4m at 0.9% copper and 0.04g/t gold Resource definition drilling has also intersected multiple positive results Drilling continuing with the goal of growing the resource base Special Report: Hillgrove Resources has found copper mineralisation outside the existing resource while drilling at its Kanmantoo operations in South Australia. The company is undertaking 20,000m of resource extension drilling and 40,000m of resource definition drilling with the aim of growing the resource of 19.3Mt at 0.77% copper and 0.14g/t gold. Drilling at the 750 diamond drill site at Kavanagh - the deepest underground drill site at the project – intercepted 2.4m at 0.9% copper and 0.04g/t gold (uncut) from 238.6m downhole in hole 25KVUG0597. In addition to this, with the resource definition drilling, there were multiple positive results, which included: 13m at 2.24% Cu and 0.13g/t Au (uncut) from 109m downhole; 2m at 1.19% Cu and 0.17g/t Au (uncut) from 108m downhole; 4.1m at 0.9% Cu and 0.06g/t Au (uncut) from 82m downhole; and 9m at 0.79% Cu and 0.28g/t Au (uncut) from 196m downhole. Hillgrove Resources (ASX:HGO) said finding this mineralisation outside the resource estimate highlighted the continuity of the Kavanagh ore body. As 25KVUG0597 provided the deepest intersection at Kavanagh West, being 200m below the existing stoping area, it indicates a new vertical extension target. Drilling from underground is on track to achieve the 60,000m target, with 5,931.6m completed in May from the fulltime operation of three underground diamond rigs. Watch: New top mining metrics for Kanmantoo copper Looking to grow the resource base Hillgrove will continue drilling in the coming months focused on investigating the potential to grow the resource base and enhance the long-term outlook at Kanmantoo. 'We are still in the early stages of the drilling program at the Kavanagh 750 diamond drill site but I'm encouraged by the results so far,' CEO and managing director Bob Fulker said. 'These are the first holes drilled in this area since underground development began and they not only reaffirm our confidence in the existing resource but also include several intersections with grades exceeding the current average in the published mineral resource estimate. 'One particularly positive result comes from hole 25KVUG0597, which intersected mineralisation approximately 200 metres below the current Kavanagh West stoping horizon on the 785 level. 'Although the intersection is narrow, it represents the deepest mineralised hit recorded at Kavanagh West to date. 'This opens up a new vertical extension target with the potential to expand the mineral resource estimate if this trend continues.' An updated resource estimate will be released in Q4 2025 following a mid-year data close off window.

VRL drilling finds new gold trend
Scout drilling has confirmed that a new gold mineralised trend is present at the Triton prospect Intersection of supergene mineralisation supports potential for significant gold at depth and along strike Verity Resources planning to grow and upgrade existing 154,000oz gold inferred resource at Korong and Waihi Special Report: Preliminary scout drilling at the Triton prospect has confirmed a new mineralised trend about 5km northwest of the existing Korong resource at Verity Resources' Monument gold project in WA's Laverton district. Shallow aircore drilling at Triton intersected bedrock gold mineralisation beneath a robust surface anomaly. Triton aligns with historical soil geochemistry of +20ppb gold and is hosted within the same Archean greenstone terrain that underpins some of WA's most prolific gold mines. Contact-related gold mineralisation at the prospect mirrors the mineralised architecture observed at Fred's Well, where drilling returned results such as 24m at 3.24g/t, suggesting that a structural corridor might be present. Adding interest, the mineralisation is supergene in nature, which is indicative of dispersion from a potentially higher-grade bedrock source at depth. Meanwhile, Verity Resources' (ASX:VRL) soil sampling at the McKenzie Well prospect has defined multiple large-scale coherent gold-in-soil anomalies, with peak values up to 96ppb gold across structurally favourable greenstone terrain. This makes it a high priority target for drilling in the next phases. The Monument gold project covers 232km2 about 40km west of Laverton and is directly adjacent to and along strike from Genesis Minerals' (ASX:GMD) 3.1Moz Mt Morgan project. Monument is surrounded by notable gold players such as Genesis Minerals. Pic: VRL Aircore drilling The company's aircore drill program of 19 holes totalling 757m targeted surface gold anomalism from soils and rock chip samples in prospective stratigraphic positions at the Triton, Star Well and Korong West prospects. At Triton, this drilling returned broad zones of supergene mineralisation, returning assays such as 12m at 0.2g/t gold from 20m and 4m at 0.2g/t from 24m. This mineralisation is at a favourable stratigraphic contact between mafic volcanics and siltstone, a known control on gold deposition in the region with a setting analogous to the nearby Fred's Well prospect. Intersecting gold within this structural-stratigraphic framework strongly supports the potential for significant mineralisation at depth and along strike. VRL plans to carry out follow-up reverse circulation drilling to test for continuity, grade improvement and deeper, high-grade feeder zones. While drilling at Star Well did not return significant gold intercepts, the company noted that it enhanced its understanding of the structural and lithological setting at Star Well. Future work at Star Well will focus on defining drill-ready targets beneath the strongest surface anomalies using detailed mapping, geophysics and potentially fresh rock testing from deeper RC drilling. Likewise, the lack of significant gold intersections did not take away from the fact that Korong West remains largely untested and highly underexplored, particularly considering its proximity to the Korong gold deposit. Further geochemical coverage, along with geophysical reinterpretation and deeper drilling, will be considered to evaluate the full potential of this prospective structural corridor. Prospect location plan and significant intercepts from recent aircore drilling. Pic: Verity Resources Other activity Over at McKenzie Well, the soil sampling outlined multiple broad and coherent gold-in-soil anomalies that cover a large area and display structural continuity. This makes it one of the most promising untested prospects within the company's regional pipeline. VRL noted the anomalous zones are coincident with mapped greenstone lithologies and potential structural intersections, which is indicative of a favourable setting for shear-hosted or intrusion-related gold systems. It adds the scale and strength of the geochemical response suggest a robust gold system may be present under shallow cover. Follow-up exploration at McKenzie Well will include infill soil sampling, detailed mapping, and aircore drill testing of the highest priority anomalies to progress the prospect to RC drilling in the next phase. Next steps Verity is currently focused on its resource upgrade and expansion strategy, targeting the existing 154,000oz inferred resource at Korong and Waihi. It has engaged Environmental Resources Management to carry out a comprehensive review and validation of historical drilling data associated with the current resource. This will determine the level of infill and twin drilling required to support a reclassification to the higher confidence indicated status. VRL will then design a targeted drill program to infill and step out from known mineralisation along the Korong-Waihi BIF corridor, which remains largely underexplored beyond the current resource boundaries. Following this resource-focused drill program, the company will then carry out follow-up drilling at the Triton prospect to test the depth extent and strike continuity of the newly identified mineralised trend. It will also conduct geochemical vectoring and structural interpretation of mineralised zones to refine drill targeting, including the analysis of multi-element pathfinder suites to identify fertile gold systems.

PTR hits impressive HM mineralisation at Rosewood
The new intersections confirm continuity, grade and thickness HM mineralisation now extends over an area exceeding 20km2 and remains open to the north Further drilling is expected to commence later this week Special Report: Drilling results from the remaining 63 aircore holes at Petratherm's Rosewood heavy mineral prospect in South Australia's northern Gawler Craton have expanded the mineralised zone, reinforcing consistency in grade and thickness. Heavy mineralisation across the Rosewood prospect now extends over an area exceeding 20km2 and remains open to the north. New intersections include: 9m at 15.1% heavy minerals (HM) from 10m, including 26.4% HM from 12m; 12m at 12.7% HM from 4m, including 7m at 17.1% HM from 5m; and 11m at 16.4% HM from 6m, including 7m at 23.8% HM from 6m and 1m at 55.7% HM from 11m. Drilling ended in high-grade mineralisation, indicating the prospect continues to expand to the north with stand-out northernmost intersections including: 8m at 13.1% HM from 6m, including 4m at 20.5% HM from 7m; 11m at 12.3% HM from 4m, including 5m at 21.4% HM from 7m; and 9m at 15.1% HM from 5m, including 6m at 20.3% HM from 8m. Within the broader mineralised envelope two high-grade, north-south trending mineralised zones have been identified at Rosewood East and Rosewood West. Metallurgical studies underway Petratherm (ASX:PTR) CEO Peter Reid said the phase 2 drill results have returned some of the company's best drill intercepts to date. 'These results have extended the high-grade mineralisation up to 1.6km further north with the mineralised envelope now exceeding 20km2,' he said. 'Two distinct zones of continuous mineralisation are now evident from the drilling, they are strongly mineralised and remain open to the north. 'Step-out extensional drilling will commence later this week which is expected to further extend the Rosewood strandline systems,' he added. 'In addition, bulk sample metallurgical studies are now getting underway which will provide an initial assessment of key elements of the project including mineral recovery processing and potential product mix. 'This will provide further insight into the quality of the Rosewood prospect.' More from Petratherm: Best drilling results to date at Rosewood Background on Rosewood Petratherm has been adding weight to the Rosewood heavy mineral discovery since figuring the prospect held potential to host the stuff in September 2024, when outcropping sampling returned between 10-50% titanium dioxide. Follow-up drilling delivered encouraging HM intersections across a continuous 15km2 area, with the mineralisation amenable to free-dig mining and conventional wet concentration processing, typical of standard heavy mineral sands operations. These developments see Rosewood as of the most promising titanium finds in Australia in recent years. Titanium is used in a wide range of applications such as aerospace, chemical processing, medical and sporting equipment due to its high strength to weight ratio, corrosion resistance and biocompatibility. Rosewood sits within the wider Muckanippie asset area, southwest of Coober Pedy in South Australia. What else is happening? Further drilling is expected to begin later this week seeking more extensions to the high-grade mineralisation, particularly to the north where some of the strongest mineralisation has been encountered.
