Estrella Resources is continuing to deliver the goods at its Lautém project in virgin Timor-Leste, with the discovery of new supergene manganese mineralisation exposed from surface at its Sica prospect. The company also received “exceptional” assay results from grab samples taken at several nearby prospects, with grades reaching as high as 57 per cent manganese.

Estrella Resources has inked a milestone joint venture and royalty deed with Murak Rai Timor (MRT), the State-run mining arm of the Timor-Leste Government, to explore for manganese, copper and gold in that country. Estrella will hold 70 per cent of the newly-formed venture that includes three exploration licenses covering a landholding of 121.5 square metres, with MRT holding 30 per cent.

Geological mapping and grab sampling by Estrella Resources has stretched its manganese strike out to 47km in Timor-Leste, with some priority samples already crushed and sent back to Perth for expert lab analysis. The company is now weighing up its business case for the potential first-ever manganese exports from the Southeast Asian country formerly known as East Timor.

Estrella Resources' hunt for manganese in Timor-Leste is heating up, with recent grab samples from riverbeds going as high as 58.4 per cent manganese at the company's newly-coined Dasidara prospect. Management says geological reconnaissance across its 503.7 square kilometres of ground has defined mineralisation through 30km of strike length as proposals to kick off trenching and drilling are maturing.

Perth-based explorer Estrella Resources has uncovered another manganese prospect in Timor-Leste, with pXRF grades from float going as high as 27.9 per cent manganese. The company's new Sauro prospect sits just 12km south-east of its Lalena prospect that just last week threw up pXRF results from grab samples going up to 57.2 per cent and 48.1 per cent manganese.

Estrella Resources has officially been granted exploration tenure of more than 500 square kilometres in Timor-Leste making history as one of the first companies to receive exploration rights in the country. The nation is looking to build its industry in this resource-rich part of the world and ASX-listed Estrella is the first through the gate.

Estrella Resources will use a $1.327 million research-and-development tax rebate from the ATO to repay a loan facility, with about $181,000 in surplus cash to be aimed at further exploring its Carr Boyd nickel project in Western Australia's Goldfields region. The company says it will continue its R&D work into mineralisation genesis and make a further claim at the end of the next financial year.

Estrella Resources has secured a prized position in what is emerging as a new mineral frontier after the Timor-Leste Government granted the company three highly-prospective new mining concessions. The acquisition of the concessions gives the company access to an area of 121.5 square kilometres in a region known to host more than 200 mineral occurrences including gold, copper, manganese, silver and chromite.

A world-first audio-frequency-magnetic survey flown by Estrella Resources over its flagship Carr Boyd nickel-copper project near Kalgoorlie in Western Australia's Goldfields region has zeroed-in on nickel-sulphide drill targets to 600m depth. The company says the helicopter-borne survey has given it a vastly better understanding of the project's geology and includes “industry-leading vision” of its highly-prospective host rocks.

Estrella Resources has confirmed the presence of a slew of multiple stacked, fractionating pegmatites during field work at its Carr Boyd project near Kalgoorlie in Western Australia's Goldfields region. The company says the outcropping pegmatites can be traced for a few hundred metres before going beneath the cover again and a follow-up works program of mapping and sampling is already underway.

An "unsolicited" lithium review at Estrella Resources' Carr Boyd nickel project near Kalgoorlie has spun out new and historical pegmatite potential – but the extent and lithium content is not yet known. The company says the approaches from a “leading global mining group” to evaluate the possibilities for LCT-type pegmatites at Carr Boyd has only reconfirmed its belief in what it believes the project may hold.

Interim feasibility work by Estrella Resources has confirmed the viability of a simple decline and two-level underground mine for its 5A nickel deposit at the company's Spargoville project near Kambalda in WA. Management has estimated the mine's capital and operating costs at $11 million, which can be represented as $US3.20 ($AU5.60) per pound of nickel produced. The current price is hovering at about $US8.30 (AU$13.30).

Estrella Resources has earned pre-qualification in the Timor-Leste Government's inaugural minerals tender process, opening up a potential pathway for the company to acquire tenure in a region known to host more than 200 mineral occurrences including gold, copper, manganese, silver and chromite. The process appears set to end the region's dearth of exploration due to a succession of long-standing geopolitical factors.

Estrella Resources has utilised a next-generation helicopter-borne electromagnetic geophysical system to identify several new conductor anomalies at its Carr Boyd project in Western Australia's Goldfields region. Multiple anomalies through a 5km strike length along the Colreavy komatiite have been recognised and, importantly, the “Target EM” system has also identified a new 3km linear zone under cover to the south of the Carr Boyd intrusion.

Estrella Resources is evaluating its Carr Boyd project in Western Australia's Goldfields region for lithium-pegmatite potential associated with a granitic or monzonitic body that intrudes the northern flanks of the mafic-ultramafic nickel host. New interpretations and a recent nickel discovery have highlighted areas of nickel potential and also indicate possible pegmatite-hosted lithium and related mineralisation within the project.

Estrella Resources' share price doubled this morning on the back of the company revealing an impending world-first helicopter-borne electromagnetic survey (TargetEM) at its Carr Boyd nickel-copper-PGE project in Western Australia. Given the significant technology and sensitivity upgrades of its new system, Estrella is intensifying its hunt for drill targets that previously evaded detection while using the older technology.

Estrella Resources has identified a slew of fresh targets at its Carr Boyd nickel project near Kalgoorlie following a review of data from its partnership with the CSIRO and results from a recent seismic survey. The company says it has highlighted 30 targets, including 15 with known nickel-copper-platinum group element intersections and another 15 hosting the right geology, but which are yet to be tested.

ASX-listed Estrella Resources has run the rule over a promising 5A nickel target at its Spargoville project, 20km south-west of Kambalda in WA's Goldfields, and has opted for an underground decline operation over open-pit mining. The company will now press full-steam ahead towards restarting the historic mining at Spargoville of nickel – now a much-needed battery metal.

Near-term nickel producer Estrella is one step closer to delivering its much-needed battery metal to the market. Glencore's Murrin Murrin operation has received a bulk sample of high-grade nickel from the company's Spargoville 5A project, 20 kilometres south-west of Kambalda. Estrella says its assays have met all the specifications from Glencore and the processing of the sample has begun.

Estrella Resources has announced an upgrade of the nickel resource estimate at its Spargoville project's 5A deposit, 20km south-west of Kambalda, with most of the resource now in the more confident “measured” category. Estrella is pressing ahead with optimisation work for a definitive feasibility study and is focused on 16 000 tonnes of massive sulphide grading 7.8 per cent nickel below 5A's existing open pit.

Estrella Resources has declared a maiden inferred mineral resource estimate of 0.86 million tonnes at 0.66 per cent nickel and 0.42 per cent copper at its T5 deposit in the Goldfields region of WA. The company says the latest estimate underpins an updated JORC exploration target of five to seven million tonnes at 0.7 to 1.5 per cent nickel and 0.3 to 0.5 per cent copper for the basal contact at its wholly owned Carr Boyd nickel project 80km north-east of Kalgoorlie.

Estrella Resources will turn its attention to upgrading its resource after the final chapter of resource drilling at its Spargoville nickel project near Kambalda in WA delivered a raft of solid intercepts. Assay results from two diamond holes sunk beneath the Spargoville 5A deposit include 2.76m at 3.58 per cent nickel from 71.46m and 2.2m going 3.17 per cent nickel from 61m.

Estrella Resources has received positive assay results showing multiple nickel intersections at the company's T5 deposit, part of its wholly owned Carr Boyd project north-east of Kalgoorlie in WA's Goldfields. The company says the results show mineralisation plunges down and to the south with a clear opportunity at depth where the deposit remains open.

Estrella Resources has been buoyed by more positive assay results and the bonus of additional key infrastructure as the company moves towards production at its Spargoville nickel project near Kambalda in WA's Goldfields. Latest results from resource drilling below the Spargoville 5A deposit include a 6.8m hit going 4.4 per cent nickel from 66.2m including 1.76m at 10.21 per cent.

Nickel-focused Estrella Resources is becoming increasingly bullish about shifting into production after receiving further high-grade assays from resource drilling at the company's Spargoville nickel project near Kambalda in WA. Significant results from its latest diamond drilling include 3.45m going 5.46 per cent nickel from 70m, containing a high-grade 1.2m at a stunning 10.85 per cent, 11.12m at 1.68 per cent from 59m and 2.7m at 2.47 per cent from 74m.

Estrella Resources says it remains on target to kick off full-scale mining of the company's 5A resource in early 2023 after further high-grade assays at its Spargoville nickel project near Kambalda in WA. With drilling coming to an end, Estrella will now move to extract between 2000 and 4000 tonnes of material for metallurgical testing. The company says plans to calculate a revised mineral resource estimate will feed into ore reserve and pit optimisation modelling.

Estrella Resources has extended its T5 deposit by 300m south after step-out diamond drilling hit semi-massive nickel-copper sulphides. The explorer says its hole, part of the company's Carr Boyd project in WA's Goldfields region, intersects 1.8m of semi-massive to globular sulphides from 929m came within a broader 21.2m mineralised zone. Down-hole electromagnetic surveys are set to commence soon at the project.

Estrella Resources has recorded a 17m intersection of semi-massive to disseminated nickel-copper sulphides at its Broonhill deposit, part of the company's Carr Boyd nickel-copper project near Kalgoorlie, in WA. The company says results show Broonhill remains open along strike, is increasing in scale and a separate deposit to the T5 mineralisation 1.5km to the south.

Estrella Resources says high-grade results from resource confirmation drilling at its Spargoville nickel project near Kambalda in WA highlight its best hope of transitioning to a producer in the near term . First assays from a hole drilled at the company's 5A resource returned a 3.4m intersection recording 8.2 per cent nickel, 0.6 per cent copper, 0.2 per cent cobalt and 21.5 per cent sulphur from 65.16m.

Perth-based nickel explorer Estrella Resources has struck nickel-copper sulphides in the first three step-out holes drilled at its T5 prospect 80km north-east of Kalgoorlie in WA's Goldfields region. The company says the intercepts show mineralisation continues to the south beyond downhole electromagnetic plates from previous drilling of the prospect at its wholly owned Carr Boyd nickel project.

Estrella Resources has begun resource confirmation drilling at its Spargoville nickel project in Kambalda as it prepares to produce a definitive feasibility study of its 5A nickel mine resource. Drilling contractor Topdrive Drillers Australia has mobilised at the project, that Estrella acquired in late 2017 with planning ongoing for an open pit cutback at the site's 5A nickel mine.

Nickel-focused Estrella Resources continues to intersect more nickel-copper sulphides in drilling at its Carr Boyd nickel project 80km north of Kalgoorlie in Western Australia. The company says it has hit a cumulative 17.5m of disseminated and blebby sulphides within a broader zone about 24m wide. The finding comes from 782m down a deep hole targeting below the company's T5 nickel discovery.

Estrella Resources has hooked onto more nickel sulphides at its flagship Carr Boyd nickel-copper project 80 kilometres northeast of Kalgoorlie in Western Australia. A single diamond drill hole yielded a significant strike of 8.07m grading 4.37 per cent nickel and 0.75 per cent copper within a larger zone of 16.2m running 3.12 per cent nickel and 0.60 per cent copper from 192.35m downhole

Estrella Resources continues to unveil the prospectivity of the intrusive igneous complex at its Carr Boyd project near Kalgoorlie in WA. The company says it has discovered more nickel-copper rich sulphides on previously untested ground at the Mossgiel and Gossan Hill prospects with mineralisation showing stark similarities to the geology of its original T5 discovery.

Estrella Resources is zoning in on more nickel-copper targets at its developing T5 discovery near Kalgoorlie in WA after the company spotted a suite of down-hole geophysical anomalies begging to be drilled. The anomalies lie tantalisingly close to the T5 deposit and suggest known mineralisation is open to the north and south, throwing up a plethora of new targets that the company will now target.

Estrella Resources has delivered another set of nickel and copper sulphides at its blossoming T5 discovery located at the company's Carr Boyd project near Kalgoorlie in WA. Estrella plunged a diamond drill hole below the discovery and intercepted a brace of separate of nickel and copper sulphide zones it says confirms the continuation of nickel-copper sulphides below the Carr Boyd mine's old workings.

Nickel explorer Estrella Resources has decided to sell its nickel rights over its Spargoville project located approximately 25km west of Kambalda in WA. After receiving several unsolicited offers the company has engaged Geolithic Geological Services to handle the sale process and it is now planning to concentrate its exploration efforts on the company's flagship Carr Boyd nickel project.

Mineral explorer, Estrella Resources continues to hit nickel and copper sulphides at its enthralling T5 discovery located at its Carr Boyd project near Kalgoorlie in WA. A step-out diamond drill hole below the T5 discovery has intercepted three separate zones of nickel and copper sulphides, including a new mineralised zone where a 3m interval grading 1.76 per cent nickel and 0.66 per cent copper was returned.

Estrella Resources has intercepted three zones of nickel-copper sulphides with a 60 metre step-out diamond drill hole below its T5 nickel-copper discovery near Kalgoorlie in WA. The company says each of the three zones contained thick widths of massive sulphides over the last 170m of the drill hole.

Nickel explorer, Estrella Resources has intercepted 12 metres of nickel-copper sulphides on previously untested ground, some 1.4 kilometres along trend from its striking T5 nickel-copper discovery near Kalgoorlie in WA. The company says the new intercept looks strikingly similar to the T5 discovery RC hole that returned 8m at 1.11 per cent nickel and 0.36 per cent copper in 2019.
