CuFe Ltd (ASX: CUF) (CuFe or the Company) is pleased to provide an update on the status of CuFe’s Tennant Creek Cu-Au project, which is owned 55% by CuFe and 45% by Gecko Mining Company Pty Ltd. The project has an existing JORC 2012 resource of 7.3MT at 1.7% Copper and 0.6g/t Gold (refer to CuFe’s ASX release dated 3 April 2023).
HIGHLIGHTS
- Detailed technical review has identified 4 high priority exploration targets to grow CuFe Tennant Creek global resources.
- Review has provided detailed information to initiate assessment of heritage and regulatory approvals for initial near term exploration program including approximately 5,000m of drilling.
- It has identified the potential to grow the Orlando resource based on existing drilling following an external review of the 2023 Orlando Resource and historical underground drill data.
- Detailed analysis to further define targets continues, including reprocessing and interpretation of historical geophysical data.
CuFe Executive Director, Mark Hancock, commented“With the ongoing exploration success of other juniors in the region, the sustained improvement in the copper market and historical highs in the gold price we have initiated a detailed technical review of our Tennant Creek project. The aim is to expand existing resources and highlight the exploration potential remaining in the area. We have developed a detailed suite of targets that we can translate to on ground exploration with an initial drill program to be executed post heritage and regulatory approvals. We see a lot of potential to add resources to underpin the future recommencement of mining in this world class mineral field.”
Technical Review and Scope
A detailed technical review of the Tenant Creek geology, historical data sets and exploration targets has been undertaken by Mr John Dobe as a technical consultant to CuFe. Mr Dobe is a geologist with >30 years of global exploration experience (predominantly Homestake/Barrick) specialising in project generation and project evaluations at all stages of exploration, from grassroots through to brownfields. John has a detailed understanding of mineral deposits with particular focus on porphyry Cu-Au, IOCG, epithermal Au, orogenic Au, Sediment-hosted Cu, SEDEX, and VHMS deposits.
The scope of the review included auditing and consolidation of historical drill hole geological and geophysical databases, exploration target review, generation and ranking. The outcomes of the review have helped derive an exploration strategy with the aim of growing the global resources at the CuFe Tennant Creek Project.
Review Findings and Target Ranking
The Gecko and Orlando Corridors are well explored and current resources are mostly well defined with multiple generations of surface and underground drilling including RAB, vacuum, RC and Diamond. The sharp and well-defined nature of the mineralisation does provide further opportunities for additional resources extensions immediately adjacent to the known deposits. Geophysical data is also abundant and wide ranging including IP, Helitem, magnetics, gravity and seismic.
Exploration targets in aim of growing the global resource have been identified within the Orlando and Gecko Corridor and have been allocated the following categories:
1. Resource extensions and infill
2. Near Resource / brownfields
3. Target Delineation
4. Grassroots / Generative
Resource extensions and infill targets have a higher degree of certainty and potential than those that are grassroots generative and conceptual in nature.
Targets have also been ranked by priority on the basis of their complexity, exploration maturity and prospectivity. Their relative potential size has been estimated based on technical review/analysis and conceptual models and projections (See Figure 1).
Figure 1: Targets defined during the technical review within the Gecko and Orlando corridors.
Four high priority targets have fallen out of the technical review that are located with both the Gecko and Orlando corridors. Spatially the targets are shown in Figure 2.
Figure 2: Location of the targets and the Orlando and Gecko Corridors
Orlando Corridor
Five targets have been identified within the Orlando Corridor, two of which are high priority, potentially adding to resources by extension and near resources / brownfields discoveries. Orlando underground resource extension includes the interpretation and modelling of the Orlando underground resources that are not included within the current Orlando Resource.
Recently MEC consulting was engaged by CuFe to review the Orlando Resources and historical drilling data. The review confirmed that there is drill hole data that supports extensions of copper and gold mineralisation from the existing open pit, into and around the historical underground workings. Currently this mineralisation is not interpreted and or reported in the existing 2023 Orlando Resource (See Figure 3 and refer to CuFe ASX announcement 3 April 2023). An immediate workstream has been initiated to develop a global resource for the Orlando deposit based on an updated validated drill hole data base including recently sourced Grade Control drilling from the Open Pit mining and historic drilling where QA/QC can be achieved. This target ranks high in terms of priority based on the short lead time with no drilling required and minimal execution costs. It also has the potential to grow the underground resource at Orlando with reasonable confidence considering the drill intercepts are confirmed and historical underground mining has recovered cooper and gold from these levels.
The second high priority target within the Orlando Corridor is an area immediately below the open pit and adjacent to the underground where there is a gap in drill coverage that leaves a portion of the resource open along strike and at depth (See Figure 3). Testing this gap will require deep drilling in the order of 350m but the potential scale of this target justifies its high ranking and priority.

CuFe Limited
Overview
CuFe Limited (ASX:CUF) is a multi-commodity exploration and development company with interest in eight projects situated throughout mature mining jurisdictions in Western Australia and the Northern Territory. The company's value proposition is predicated on its high-grade premium product iron ore projects as well as its exposure to copper, lithium and niobium. Its exploration portfolio includes mature copper targets at Tennant Creek, drill-ready lithium targets at North Dam, and greenfield exploration ground in close proximity to WA1's recent niobium discovery.
Tennant Creek hosts a mineral resource estimate of 7.3 million tons (Mt) at 1.7 percent copper and 0.6 grams per ton (g/t) gold for 127 kt copper and 145 koz gold. CuFe currently owns a 55 percent interest over 240 kilometres of the highly-prospective tenure, situated in the Northern Territory. CuFe's near-term plan for the mine, based on detailed mine planning, involves a staged cutback of the Orlando open pit to gain access to an ore supply for fast start options.
CuFe is also evaluating the Yarram project, as its close proximity to the Darwin port gives it the potential for low opex.
Lastly, CuFe has a low-risk 2 percent NSR gold royalty over the Northern Star Crossroads project, where mining is expected to commence in 2024.
CuFe is led by a highly experienced management team adept at identifying opportunities, making discoveries, evaluating and developing projects and maintaining operations.

Key Projects
Copper
Tennant Creek
The Tennant Creek project is located in the highly prospective Gecko-Goanna copper-gold corridor of the Northern Territory. A mature project comprising three high-grade copper and gold mineral resources, it contains a combined JORC 2012 mineral resource of 7.3 at 1.7 percent copper and 0.6 g/t gold for 127 kt copper and 145 koz gold. Highly-prospective for further resource growth from resource extensions and new discoveries, Tennant Creek is also located in close proximity to grid power, a gas pipeline, the Stuart highway and the rail line to Darwin.
The area where Tennant Creek is hosted is a re-emerging mineral field with recent neighbouring exploration success from companies such as Emmerson Resources (ASX:ERM) and Tennant Minerals (ASX:TMS). Near-mine targets include the potential to extend resources and open enrichment within the Orlando and Gecko structural corridors.
The current focus for Tennant Creek is to identify and drill high-potential exploration targets with a view to growing the resource base while considering a staged cutback of the existing Orlando open pit to gain access to an ore supply for a fast start option.
Bryah Basin JV projects
Through wholly owned subsidiary Jackson Minerals, CuFe has a 20 percent interest in roughly 804 square kilometres of highly-prospective tenements proximal to the former Sandfire Resources' (ASX:SFR) Doolgunna project and Degrussa copper gold mine, as well as several other prominent gold and copper prospects. Collectively known as the Bryah Basin JV projects, the tenements are currently subject to joint ventures and farm-ins with several companies. The most prominent of these is the Morck Well project, which is under an exploration licence with Auris Minerals (ASX:AUR) alongside the Forrest project.
The Morck Well project tenements cover an area of 600 square kilometres in the highly-prospective region, which has been recognized to have high iron ore potential.
Lithium
North Dam
The North Dam project is a highly prospective lithium tenure situated in the emerging Yilgarn Lithium Belt. Located roughly 50 kilometres south-southeast of the township of Coolgardie, the project is contained within the same lithium belt that contains known spodumene deposits such as Mt Marion, Pioneer Dome, Bald Hill, Manna and Buldania. There have also been several well-known junior exploration successes immediately adjacent to the tenement, including Kali Metals (ASX:KM1), Marquee Resources (ASX:MQR) and Maximum Resources.
To date, work on the project has included defining prospective pegmatites through rock chip sampling, soil sampling and geological mapping. Anomalous lithium and key pathfinder elements have also defined a prospective corridor of roughly 3.5 kilometres in strike length. Columbite and tantalite rock chips selected from a stream bed also contain up to 44 percent niobium and 14.53 percent tantalum.
CuFe has also completed a recent heritage survey and, pending results and conditions, plans to commence a maiden drill program.
Tambourah
The 100 percent owned Tambourah Tenure is a prospective lithium tenure with known gold occurrences. Located roughly 90 kilometres south of the Pilgangoora and Wodgina lithium complexes, and 175 kilometres south of Port Hedland, the project was historically explored for gold and contains known gold occurrences within alluvial material and reef systems. Current work on the project to date has involved geological mapping and rock chip sampling.
Niobium
West Arunta
The fully owned West Arunta consists of three tenements located in the highly-prospective region of the same name. The tenure is known to be prospective for carbonatite-hosted niobium and rare earth element mineralization. Spanning roughly 220 square kilometres, it surrounds Lycaon Resources' (ASX:LYN) Stansmore project and is located 70 kilometres north of several prominent recent discoveries.
CuFe has not yet finalised native title arrangements to commence work in the ground so in the meantime it engaged Southern Geoscience Consulting to undertake a geophysical review of publicly available airborne magnetic data for the tenements including re-processing of said data and 3D unconstrained inversion modeling. Analysis of the total magnetic imagery revealed three anomalous areas across the package, resulting in nine target anomalies for further investigation and exploration.
Iron
Yarram
The Yarram iron ore project is a mature development opportunity with the potential for low-cost production. CuFe currently holds a 50 percent interest in the project, which includes operatorship. Partially located on an existing mining lease on freehold land, Yarram has a high-grade DSO resource of 5.6 MT at +60 percent iron as well as a low-grade component of 7.1 Mt with the potential for beneficiation.
Situated 110 kilometres from Darwin Port and adjacent to underutilised mining infrastructure, Yarram also features favourable ore body geometry, with existing infrastructure and services contributing to its low capex and opex.
An initial diamond drilling program provided HG core from two deposits within the project. Physical and thermal metallurgical testing confirms the generation of a lump product with roughly 41 percent yield, elevated gangue levels in the very fine fractions and acceptable thermal and materials handling properties, making it suitable as a blast furnace lump burden feed.
CuFe has also undertaken geotechnical testwork on the diamond drill core to provide parameters for pit optimizations and designs. Final pit shells and a high-level mine schedule have been developed for use in regulatory approvals.
Gold Royalty
Crossroad gold project
Through fully owned subsidiary Jackson Minerals, CuFe holds a 2 percent net smelter royalty over M24/462, which contains Northern Star's (ASX:NST) Crossroads gold project. This project is the subject of a recently approved mining proposal envisaging the mining of 2.67 Mt of gold-bearing ore. The project is expected to commence sometime in 2024 and run for a 36-month period, with the majority of ore mined in the second and third years after pre-stripping.
This project represents a potential near-term revenue source for CuFe with no associated costs.
