Latin Resources Limited (ASX: LRS) (“Latin” or “the Company”) is pleased to advise the latest assay results from diamond drilling at the Company’s 100% owned high-grade Colina Lithium Prospect (“Colina”), one of several prospects within the Salina Lithium Project in Brazil, has confirmed the previously reported visual spodumene estimations in hole SADD016. These results have surpassed all previous intersections, returning 25.24m @ 1.25% Li2O1 from the central area of the Colina Prospect. Mineralisation remains open to the south.
HIGHLIGHTS
- Drilling at Colina has confirmed the presence of additional wide, spodumene bearing pegmatites below any previously reported intersections, with recent drill hole SADD020 intersecting 7.46m of pegmatite with estimated 15-20% spodumene.
- The latest results from diamond drilling in the centre of the Colina Prospect have confirmed the previously reported wide spodumene pegmatite intersection in drill hole SADD016, returning 25.24 m @ 1.25 % Li2O from 94.14 m.
- The Company will undertake preliminary Dense Media Separation (DMS) metallurgical test work on the Colina Prospect drill core as a part of the Company’s fast-track strategy.
Latin Resources’ Exploration Manager, Tony Greenaway, commented:
“Our drilling at Colina continues to return excellent results, with these latest assays from drill hole SADD016 being our best intersection to date, further highlighting this central zone of Colina as a priority area for the Company.
“The discovery of a new spodumene pegmatite at depth in hole SADD020, below all our previously reported pegmatites, has highlighted the upside at Colina. We know we have additional pegmatites to test further out to the west of Colina, and now we have proven the potential for additional stacked pegmatites at depth. The more we drill at Colina, the better this prospect seems to get. Based on this newly discovered pegmatite, the Company will continue to push our drilling below our previous target depths to fully evaluate this emerging new zone.
“We are also very pleased to get some initial metallurgical test work underway. We have had very productive discussions with a number of specialist consultant groups during the recent PDAC conference including metallurgical, mining, and environmental permitting consultants. We outlined and have initiated some dense media separation test work, which will provide the Company with preliminary recovery and potential lithium concentrate grades, as well as providing guidance for a more detailed metallurgical test work program to be undertaken as part of the Company’s strategy to fast-track our exploration activities to a Maiden JORC Mineral Resource.”
Colina Prospect – Resource Definition Drilling
Latest assay results from diamond drilling at the Company’s 100% owned Colina Lithium Prospect, part of the broader Salinas Lithium Project in Brazil, have confirmed the grade of the previously reported wide pegmatite in hole SADD016 (Figure 1 and Figure 2) including2:
- SADD0016: 25.24m @ 1.25% Li2O from 94.13min
including: 7.00m @ 1.52% Li2O from 97.00m
and: 9.19m @ 1.51% Li2O from 109.00m
Visual logging of hole SADD017 drilled down dip to the east of hole SADD016, has shown multiple separate wide pegmatites (Figure 3), with the Company’s on-site field teams estimating significant zones of spodumene in the logged pegmatites (Refer to Table 1 for details).
In addition to these two results, SADD020 drilled approximately 260m to the south of SADD016, has uncovered a new thick pegmatite below any previously reported intersections, with a zone of 7.46m of spodumene bearing pegmatite at a depth of 207.08m own hole (Figure 2 and Figure 4), with logging estimating between 15-20% spodumene3.

These results highlight the significant upside potential for the discovery of new pegmatite zones within the Colina Prospect. With the imminent arrival of additional, larger drilling rigs capable of reaching greater depths, the Company continues to push drilling beyond previously planned depths to fully evaluate this new zone.

Red Mountain Lithium Discovery Bolstered with More Outstanding Thick Intersections
Key Highlights
- Multiple lithium intersections reported in assay results for the next four holes, RMRC004-007, with intersections up to +80m thickness, including:
- RMRC004: 83.8m @ 1,230ppm Li from 16.8m.
- RMRC005: 80.8m @ 1,270ppm Li from 56.4m
- RMRC006: 62.5m @ 1,070ppm Li from 6.1m and 70.1m @ 1,090ppm Li from 89.9m
- RMRC007: 74.7m @ 1,160ppm Li from 18.3m
- Intersections sit mid-project within 4.6km of strike length drilled to date at Red Mountain.
- Assay results for the remaining four drill holes expected in late July.
Assay results from the second batch of samples include the following drill intersections:
- RMRC004 : 13.7m @ 1,070ppm Li / 0.57% Lithium Carbonate Equivalent1 (LCE) from surface
- 83.8m @ 1,230ppm Li / 0.65% LCE from 16.8m
- RMRC005 : 26.0m @ 656ppm Li / 0.35% LCE from 3.0m
- 80.8m @ 1,270ppm Li / 0.68% LCE from 56.4m to End of Hole
- RMRC006 : 62.5m @ 1,070ppm Li / 0.57% LCE from 6.1m
- 15.3m @ 896ppm Li / 0.48% LCE from 71.6m 70.1m @ 1,090ppm Li / 0.58% LCE from 89.9m
- RMRC007 : 74.7m @ 1,160ppm Li / 0.61% LCE from 18.3m
- 25.9m @ 1,580ppm Li / 0.84% LCE from 115.8m
This second batch of assays, from drill holes located centrally within the group drilled so far (Figure 1), demonstrate thicker intersections than those previously announced, with all four holes intersecting +70m zones grading over 1,000ppm lithium. These outstanding results indicate the scale and grade potential at Red Mountain, as it continues to emerge as a project of significance in North America. Assays for the final four holes from the campaign are expected to be received later this month, which, along with other results, will allow the Company to determine the next steps at this highly prospective Project.
Astute Chairman, Tony Leibowitz, said:
“Our confidence in the scale and significance of this discovery continues to increase with each successful drill-hole at Red Mountain. Assays from the latest four holes have exceeded expectations and returned some very thick, high-grade intercepts which have confirmed robust lithium mineralisation in the middle of the project, between intersections from the discovery holes.
“With final assay results expected for the remaining four holes shortly, data from all holes will then be integrated into an updated geological model for Red Mountain with a view to expediting the process to achieving a maiden Mineral Resource Estimate.”

About Lithium Carbonate Equivalent (LCE)
Unlike spodumene concentrate, which is a feedstock for a value-added battery product, Lithium Carbonate is a principal lithium-ion battery product, which may be used directly in battery production or converted to other battery products such as lithium hydroxide. The Benchmark Mineral Intelligence Lithium Carbonate China Index priced lithium carbonate product at US$13,710/t6 as of 12 June 2024.

Exploration Program Underway at Corvette River Lithium, Gold, Copper & Silver Project in Quebec
The Project consists of several claim areas, including Felicie on the Corvette Lithium Trend which hosts Patriot Battery Metals’ world-class Corvette Lithium Project2 and the West Eade and East Eade claims on the parallel Corvette South Trend, approximately 12 km to the south. Both trends are on the prolific Lac Guyer greenstone belt in the tier-one global mining jurisdiction of Quebec, Canada (see Figure 1).
Phase 1 of the program will investigate and prioritise zones across the extensive claims areas for further work and follow up drilling. The program will include extensive geological mapping, excavator trenching and channel sampling, for multi-element assaying, using a team of geologists, support staff, excavators and an air support team. Field logistics are supported by helicopters, including heavy lift helicopters, to move excavators, required equipment and personnel. The program is being phased, given the limited access to heavy lift helicopters during this period. The program is sequential, initially focussed in the Felicie area (see Figure 1), to be followed by the East Eade and then the West Eade claim areas.
The primary objectives of the program are to investigate identified target locations through field mapping of structures and outcrops, extensive excavator trenching and channel sampling to finalise planning positions and the priority of follow-on drill targets in the following project locations:
- Felicie Project – Field map, trench and sample structures and outcrops associated with previous rock chip sampling that included grades of up to 4.16 g/t Au, 44.1 g/t Ag and 0.23% Cu3 from a zone of 180m strike-length open in all direction.
- East Eade – Extensive investigation of an approximately 300m wide complex fold-closure, which included previous assays of up to 29.7 g/t Au and 12 g/t Au3 See photographs of East Eade below.
- West Eade – Further investigate areas around historical sample sites with assays of up to 11.45g/t Au3 and more recent rock chip sampling results including 3.37 g/t Au over 3m3.
- Lithium Targets – Follow up on Lithium bearing pegmatite targets that have been previously reported, including CR1 (mapped over 1.6 km4) at Felicie and CS15 at West Eade (see Figure 1)

Metals Australia CEO Paul Ferguson commented:
“It’s pleasing to be under way with phase 1 of our field exploration program at Corvette River. The commencement of this program is a result of a lot of great work by our team and our contractor, Magnor Exploration. We have developed a detailed and prioritised exploration program targeting lithium as well as gold, silver and copper and put in place a contract to allow this important work to be completed during the summer field season, when ground truthing is possible in Quebec. Importantly the program phasing recognises the challenges associated with accessing heavy lift helicopters during the peak summer period.
We are now on the ground with a dedicated team of geologists and field staff, including excavators. The team will be able to follow up on the targets, associated structures and outcrops that have been identified from previous sampling. This will allow accurate positioning of trenching and channel sampling. The outcomes of this work will result in a well-defined and prioritised list of drill targets – which will be the subject of phase 2 of the program.
This program will follow up on the highly prospective lithium pegmatite targets as well as high-grade gold and silver target zones we have communicated previously. I look forward to communicating the results of phase 1 when they are available.
We continue to aggressively progress all our high-quality projects on their pathway through exploration and, when results warrant, into development. Four of our projects are now pending government approval for their next phase of exploration, including Lac Carheil, which also has active prefeasibility study work underway. It’s been an incredibly active period of planning, permit applications and work-program contracting. We are now seeing the field exploration stages starting to emerge – with Corvette River now fully permitted for advanced exploration target testing.
We are only able to advance this work because we have a very supportive board, a dedicated and driven team and the financial capacity to fund the programs we have planned. Currently, there is no value ascribed to our projects by the market and we have a market capitalisation well below cash backing, which is highly unusual. Given the high-quality pipeline of projects we are progressing and the opportunities they represent, I expect the balance of 2024 and beyond to represent exciting times for the Company.”
