NickelSearch Limited (ASX: NIS) (NiS or Company) is pleased to provide an update on diamond drilling completed at the Sexton Prospect at its Carlingup Nickel Sulphide Project (Carlingup) near Ravensthorpe in Western Australia. Both diamond drillholes (DD) at Sexton intersected visual sulphides1 in the UMH and LMH, with both horizons intersected at shallower depths than expected in the second DD.
KEY HIGHLIGHTS
- Massive sulphide mineralisation intersected in both the Upper Mineralised Horizon (UMH) and Lower Mineralised Horizon (LMH) in two diamond drillholes at the Sexton Prospect.
- Multiple sulphide intersections previously reported over a 9.85 metre interval in diamond drill hole 23NRD028.
- Diamond drill hole 23NDD030 intersected massive sulphides in the same horizon, which demonstrates the nickel mineralisation continues 60m further along strike, extending the total strike length to 250m.
- Assays from the two diamond holes at Sexton expected in early August, and follow-up downhole electromagnetic (DHEM) surveys are now planned for these diamond holes to further test the extent of the sulphide mineralisation, which exhibits a strong DHEM anomaly response.
- Diamond drilling underway at the high priority B1 Prospect, where recent reverse-circulation (RC) drilling intersected nickel sulphides (see announcement 25 May 2023).
NickelSearch’s Managing Director, Nicole Duncan, commented:
“We are delighted to report that we have once again intersected visual sulphides, including massive sulphide mineralisation, in our diamond drilling program at Sexton, one of our highly prospective targets at Carlingup.
“The hole confirmed the presence of nickel sulphide mineralisation sitting in a structure located at relatively shallow depths of ~145m and starting quite close to surface at ~40m, which is particularly pleasing. This mineralisation was intersected shallower than anticipated, and our planned DHEM surveys in the DD will allow for more constrained models and show where the intersections are in respect of the new models. We eagerly look forward to assay results in the coming weeks.”
SEXTON DIAMOND DRILLING
The drilling program at Sexton targeted two distinct bodies of mineralisation encountered in earlier RC drilling and corroborated by DHEM surveys. The primary aim for the drilling was to identify the massive sulphides associated with the LMH, with the holes also designed to test the potential for further nickel sulphide mineralisation within the UMH.
Analysis following completion of the drilling confirms the overall strike length of Sexton mineralisation to extend to 250m and remains open both up- and down-plunge. To date, the drilling has shown there are multiple horizons of nickeliferous sulphide, shallowly plunging to the southeast, with the up- and down- dip extents undefined and open along strike. The mineralisation intersected is at the upper and lower contact of a banded iron formation (BIF) unit, within the ultramafic. In addition to sulphides on the BIF contacts, there are sulphides internal to the ultramafics. The amount and thickness of sulphide that has been intersected in each hole is variable, which is not uncommon in nickel sulphide systems that can pinch and swell.
The two holes successfully intersected sources of the DHEM plates modelled from the previous RC drilling. The intersections were shallower than anticipated, with multiple sulphide intersections. The planned DHEM surveys will now be completed to allow for more constrained models and in conjunction with assay results allow for the generation of follow up drill targets to extend mineralisation and vector in on higher grade zones.

LOGGING RESULTS
In the first diamond hole at Sexton (23NRD028), the mineralisation is spread over nine metres and includes a number of intervals of various thickness of net textured/matrix to semi-massive/ massive sulphides. The sulphides are predominantly pyrrhotite +/- pentlandite and pyrite, with minor chalcopyrite.

June 2024 Quarterly Report
HIGHLIGHTS
- High impact, low cost regional exploration activities continuing at the Pulju Project.
- Analysis of an important, extensive new Bottom of Till (“BOT”) drilling database (9,632 samples) covering the entire Pulju Project area, recently acquired from the Geological Survey of Finland (GTK), is underway.
- Detailed summer mapping program underway focused on better characterising the extensive areas of known nickel/copper mineralisation and outcrop within the regional exploration licences at Pulju to prioritise future drilling targets.
- Positive progress on the metallurgical test work program for the Hotinvaara Resource to confirm potential recoveries and concentrate grades, with final results expected in Q3 2024.
- Discussions with potential strategic partners remains ongoing.
PULJU NICKEL PROJECT
The known nickel mineralisation in the CLGB is typically associated with ultramafic cumulate and komatiitic rocks with high-grade, massive sulphide lenses and veins enveloped by very large, lower grade disseminated nickel sulphide near-surface. The disseminated nickel at Pulju is widespread and indicates the presence of a vast nickel-rich system.
Following the conclusion of the 2023 drilling campaign, in March 2024, Nordic Nickel reported an updated Mineral Resource Estimate for the Hotinvaara Prospect at the Pulju Project which now comprises 418 million tonnes grading 0.21% Ni, 0.01% Co and 53ppm Cu for 862,800 tonnes of contained Ni, 40,000t of contained Co and 22,100t of contained Cu1.
Pulju is located 195km from Boliden’s Kevitsa Ni-Cu-Au-PGE mine and 9.5Mtpa processing plant in Sodankylä, Finland. Kevitsa provides feed for the 35ktpa Harjavalta smelter, which is located approximately 950km to the south and processes concentrate from Kevitsa’s low-grade disseminated nickel sulphide ore (Mineral Resource Estimate Ni grade ~0.21%). Europe’s only other smelter is Terrafame’s 37ktpa Sotkamo smelter, located 560km south-east of Pulju.

Management Comment
Commenting on the June Quarter, Nordic Nickel Managing Director, Todd Ross, said: "We are very pleased with the progress made during this quarter despite continued challenging market conditions.
“The acquisition of the extensive BOT drilling database combined with historical drilling results and geophysics across Pulju provides us with a wealth of data to guide our future exploration efforts. This data, combined with the third summer mapping program now underway is another critical step in identifying new drilling targets and advancing our understanding of the Pulju Project's geology.
“Additionally, the ongoing metallurgical test work at Hotinvaara is crucial for assessing the economic potential of the project and advancing an initial scoping study, and we eagerly anticipate sharing the final results in the coming quarter.
“These activities underscore our commitment to advancing the Pulju Project and our strategic vision of supplying sustainably sourced nickel and battery metals to Europe. With that in mind, discussions with potential strategic partners continue which will allow us to ultimately fully unlock the value of Pulju for our shareholders.

Drilling Delivers 10.2m @ 2.3% CuEq, and DHEM Expands Further Potential in all Three Directions at Horden Lake
Highlights
- Shallow drilling delivers 10.2m @ 2.3% CuEq1 in HN-24-103
- Sits within wider 28.6m @ 1.05% CuEq from 74m.
- Expands the width of expected mineralisation in the open pit zone of the deposit.
- Assays confirm 270m down-plunge continuity from surface, linking with previously reported HN-24-100
- 14.6m @ 0.84% CuEq from 272m, incl 5.7m at 1.41% CuEq in HN-24-104.
- 7.3m @ 0.78% CuEq from 165m, and 13.2m @ 0.77% CuEq from 180.1m in HN-24-102.
- Up to 600m SW extended zone now defined by both DHEM and drilling as having strong potential for down-plunge extensions
- HN-24-104 off-hole conductor extends 170m down-dip, for a potential 400m total depth extent, which may remain open.
- Plates continue to extend the mineralised zones and connect with previously reported drilling and plates in HN-24-96,-97 and -98, highlighting the potential for southern zone mineralisation continuity from the central zone.
- Infill delivers continuity of mineralisation within the 2022 resource open pit shell
- 15.6m @ 0.88% CuEq from 121m, incl 5.7m @ 1.41% CuEq in HN-24-101.
- All intersections show mineralisation in Au, Ag, PGM and Co by-products never previously assayed in this area, and represent important upside to the metal endowment reported in the 2022 mineral resource estimate.
- Assays from 21 holes remain pending, including multiple step-out and DHEM results across zones of open mineralisation.
Managing Director, Mr Fairhall said:
“Horden Lake continues to deliver - from both step-out, and infill from historical drilling. In the shallow areas, results indicate excellent continuity, in places widening, of expected mineralisation, along with a suite of valuable by-products which were overlooked in previous drilling.
Excitingly, deeper drilling and DHEM again combine to show excellent down plunge continuity of the deposit, and the huge potential for it to continue at depth. We now have a zone over 600m extending the mineralisation strike length that exhibits strong potential for expansive down-plunge extension with further drilling, potentially similar to that observed in the central zone which extends to over 490m vertical (and remains open).
Overview
Horden Lake is a copper dominant Cu-Ni-Au-PGM-Co Project located 131km north-northwest of Matagami, in Quebec Canada. The Project hosts an indicated and inferred mineral resource estimate of 28mt at 1.5% CuEq, as a result of over 52,464m of drilling previously completed on the property. Pivotal has recently completed a 7,097m / 34 hole diamond drilling campaign of which 1,800m / 9 holes have been reported prior to this announcement.
The objectives of the drilling program were to infill missing by-product multi-element assay information, target resource expansion potential (which remains open at depth across its full extent) and collect a distribution of metallurgical sample for a complete test work program. Downhole EM surveys have also been completed to dimension future exploration potential and targeting.

Blackstone Minerals
Investor Insights
Blackstone Minerals is well-positioned to leverage a projected nickel supply deficit as it strives to become a vertically integrated producer of low-cost, low-carbon, battery-grade nickel. Key to this is Blackstone’s Ta Khoa project in Vietnam, an emerging hub for the electric vehicle market.
Overview
As the world moves closer to a sustainable net-zero future, the need for battery metals continues to mount and nickel may soon be among the metals to see a supply crunch. Though its roots are in the stainless steel sector, it's also a critical component of lithium-ion batteries.
Given that many nations are aiming to replace combustion vehicles with electric cars by 2030, the metal is already experiencing a massive spike in demand. Benchmark Minerals expects the need for battery-grade nickel will increase about 950 percent by 2040.
It's imperative to ramp up global nickel production but the resource sector, for its part, must do so with a much-reduced carbon footprint to influence the sustainability of the entire value chain. Blackstone Minerals (ASX:BSX,OTC:BLSTF,FRA:B9S) recognizes this. As a vertically integrated producer of low-cost, low-carbon nickel, the company aims to become a leading source of low CO2 emission nickel sulphide. Its flagship Ta Khoa project in Vietnam is representative of that goal.
Blackstone Minerals business structure schematic
With over 20 active mines and a burgeoning technology sector, Vietnam is on the road to becoming a hub of electric vehicle production and innovation, with low labor costs and regulated electricity pricing further driving its growth. Steadily increasing foreign direct investment in the region is indicative of this as the country seeks to attract $50 billion in new foreign investment by 2030.
Blackstone is uniquely positioned to take advantage of this, thanks to two factors. US President Joe Biden's Inflation Reduction Act, which came into force in August 2022, represents the largest investment into climate action in United States history. A similar initiative is rolling out in the European Union (EU), which maintains a Free Trade Agreement with Vietnam — something multiple partners of the company have expressed interest in.
Blackstone's Ta Khoa Project consists of two streams, the Ta Khoa Nickel Mine and the Ta Khoa Refinery. Recent milestones point to Blackstone’s commitment to advancing this game-changing project.
These milestones include a memorandum of understanding with Cavico Laos Mining to collaborate in a number of areas associated with CLM’s nickel mine in Lao People's Democratic Republic and supply of nickel products for Blackstone’s Ta Khoa Refinery in Vietnam.
Blackstone also partnered with Arca Climate Technologies to further investigate the carbon capture potential at the Ta Khoa Project through carbon mineralisation, and explore opportunities to utilise Arca’s carbon capture technologies within the project.
In a bid to collaborate on the supply of renewable wind energy to the Ta Khoa Project, Blackstone signed a direct power purchase agreement with Limes Renewables Energy.
Blackstone received AU$2.8 million as an advance from a research & development (R&D) lending fund backed by Asymmetric Innovation Finance and Fiftyone Capital. The advanced payment reflects the significant investment by Blackstone to develop the Ta Khoa Refinery process and Blackstone’s unique strategy to convert nickel concentrate blends into battery products in the form of precursor cathode active material (pCAM).
In December 2023, Blackstone entered into an option agreement with CaNickel Mining to acquire the Wabowden nickel projectlocated in the world-class Thompson Nickel Belt in Manitoba, Canada.
The Wabowden project will have the potential to fill the Ta Khoa Refinery, removing dependence on third party feed sources.
The company has signed a non-binding MOU with the Development for Resources Environmental Technology joint stock company (DRET) to investigate opportunities to repurpose and trade waste material (or residue) from the Ta Khoa Refinery into construction material products. Moreover, it has also progressed the Ta Khoa Refinery byproduct offtake strategy with Vietnam Chemical Group (VinaChem), PV Chemical and Equipment Corporation (PVChem) and Nam Phong Green Joint Stock Company (Nam Phong) to sell Ta Khoa Refinery byproducts, being manganese sulphate (or epsomite) and sodium sulphate.
As the company plans to build a global nickel business, Blackstone signed a non-binding memorandum of understanding with Yulho Co. Ltd (Yulho) and EN Plus Co. Ltd (EN Plus) to establish a collaboration across the businesses including EN Plus and Yulho who are in joint venture on the Ntaka Hill nickel sulphide project in Tanzania, and the Dinagat Island nickel laterite project in the Philippines.
Company Highlights
- The global nickel market is currently entering a structural deficit, with demand expected to grow 950 percent by 2040.
- Blackstone Minerals is well-positioned to address this deficit as a vertically integrated producer of low-cost, low-carbon nickel.
- Blackstone's flagship project Ta Khoa is a brownfield project situated in Vietnam, one of the lowest capital cost countries in the world and an emerging hub for the electric vehicle market with vast reserves of nickel.
- Vietnam is an increasingly attractive region for investment with direct foreign investments that grew from $1.3 billion in 2000 to $15.6 billion in 2020.
- The Ta Khoa project also has infrastructure advantages, via the existing Ban Phuc mine, and processing facilities, access to low-cost and underutilized hydroelectricity, a trained labor force and support from the local government.
- Blackstone Minerals’ downstream pre-feasibility study confirms a technically and economically robust hydrometallurgical refining process to upgrade nickel sulphide concentrate to produce battery-grade nickel.
- Blackstone’s key nickel and cobalt feedstocks for the Ta Khoa Refinery Pilot program were delivered to the metallurgical laboratory in Western Australia as of April 2022.
Key Project
Ta Khoa
Blackstone holds a 90 percent interest in the Ta Khoa Nickel-Copper-PGE Project, located 160 kilometers west of Hanoi in the Son La Province of Vietnam. It includes an existing modern nickel mine built to Australian Standards, which is currently under care and maintenance. The Ban Phuc nickel mine successfully operated as a mechanized underground nickel mine from 2013 to 2016.
Blackstone intends to complement the existing mine through the installation of a large concentrator, refinery and precursor facility, supporting integrated on-site production of nickel, cobalt and manganese precursor products for the Asia-Pacific market. One of Blackstone's key Research and Development objectives with Ta Khoa is to develop a flowsheet that will support this production.
To fulfill this goal, Blackstone is focusing on a partnership model, collaborating with groups committed to sustainable mining. It is also working to minimize its carbon footprint and implement a vertically integrated supply chain.
Project Highlights:
- Multiple Massive Sulphide Deposits: The Ta Khoa project features several incredibly promising deposits including King Snake (up to 4.3 percent nickel and 18.2 grams per ton (g/t) PGE), Sui Phong (2.95 meters @ 2.42 percent nickel, 0.52 percent copper, 0.06 percent cobalt and 0.05 g/t PGE), and Ban Chang. The project is also the site of the Ban Phuc nickel mine, which was operated from 2013 to 2016 by Asia Mineral Resources, along with several exploration targets that have yet to be tested.
- Experienced Leadership: Internally, Blackstone’s owners’ team brings over 50 years of experience in leadership roles at major nickel mines and refineries globally. This experience has been complemented by ALS Group, Wood, Future Battery Industries CRC, Curtin University and the Electric Mining Consortium.
- Large Reserve and Mining Inventory: The entirety of Ta Khoa is estimated to contain probable reserves of 48.7 Mt at 0.43 percent nickel for 210 kilotons (kt) of nickel and a mining inventory of 64.5 Mt at 0.41 percent nickel for 265 kt nickel. This excludes Ban Khoa and other developing prospects.
- A Long-lived Project: The Ta Khoa mine is expected to produce a yearly average of 18 kt of annual nickel concentrate over its ten-year lifespan. Blackstone believes the refinery can potentially extend its life past ten years.
- An Established Mining Operation: Existing infrastructure onsite includes a 450 ktpa Mill and mining camp. The mine will also benefit from a highly supportive community and favorable government legislation — Blackstone is committed to collaborating with community stakeholders in the project's development.
- Feed Flexibility: Ta Khoa's refinery will offer multiple feed options, including nickel concentrate, mixed hydroxide precipitate, nickel matte and black mass. This flexibility greatly improves the security and greatly reduces the risk of the project overall.
- Valued Partnerships: Blackstone is collaborating with multiple industry leaders and groups in the development of Ta Khoa
- Compelling Pre-feasibility Study: The financial outcomes of a base case pre-feasibility study on the project are promising. Based on a conservative NCM811 precursor price forecast, Ta Khoa displays an exceptional internal return rate on capital invested.
- Integrated Vertical Strategy: Blackstone is constructing both the Ta Khoa mine and refinery against a highly supportive ESG, macroeconomic and fiscal backdrop. This along with Ta Khoa's low capital intensity gives the company a significant advantage over competitors. Said low intensity is the result of multiple factors, including competitive labor costs, favorable regulations and low-cost renewable hydroelectric power.
- A Leader in Low Emissions: Independent assessments from Digbee, Minviro and Circulor, alongside an audit from the Nickel Institute, have confirmed that Ta Khoa will be the lowest-emitting flowsheet in the industry, at 9.8 kilograms of CO2 per kilogram of precursor with opportunities for even further reduction.
- Promising Pilots: With the support of ALS and process engineering partner Wood, Blackstone recently completed a 12-month programme of work that developed a scaled version of its concentrate to sulphate flowsheet. The refinery, which processed more than 9 tonnes of concentrate and MHP, successfully achieved battery-grade nickel sulphate of 99.95 percent, with a nickel recovery rate of 97 percent.
- Current Roadmap: Blackstone's next priority is to complete a series of definitive feasibility studies. Once those are complete, it will focus on fully integrating the mine into the electric vehicle consumer supply chain and finalizing its refining partnership structure.
