ASX:IR1 - ASX RELEASE I 9 October 2024
Iris Achieves High Purity Spodumene Concentrate from Beecher Project
IRIS Metals Limited (ASX: IR1) (“IRIS” or “the Company”) is pleased to announce that the Company has received results from metallurgical test work completed on spodumene bearing pegmatites from the Beecher Project, located in South Dakota, USA which has demonstrated the ability to achieve a high purity spodumene concentrate, exceeding 6.0% lithium oxide (Li2O) content.
HIGHLIGHTS
-
Metallurgical test program from the Beecher Project has produced a 6.1% Li2 spodumene concentrate, with lithium recovery exceeding 82%
-
Testing produced high purity spodumene concentrate, with samples yielding as low as 0.25% Fe2O3, considerably below industry specifications for concentrate of <1.3% Fe2O3
-
IRIS is currently planning next steps which include bulk sample processing with Dense Media Separation (DMS) and further refinement of the spodumene concentrate from the Beecher Project into lithium carbonate
IRIS Metals President of U.S. Operations, Matt Hartmann, commented:
“The results of our metallurgical test work at the Beecher Project are very exciting. IRIS has now demonstrated the ability to develop a high purity spodumene concentrate, confirming the processing viability of our South Dakota deposits that host some of the largest spodumene crystals in the world.
The South Dakota team is quickly moving to further refine our process flow sheet and complete process test work on additional spodumene bearing pegmatites, with the potential of a near-term bulk sampling effort. IRIS is advancing efforts on several fronts as we continue to unlock value across our substantial holdings in South Dakota.”
Beecher Project Metallurgical Testing
The primary objective of the metallurgical testing program was to assess the liberation and recovery of lithium rich spodumene within the Beecher pegmatite within the Beecher Project area and confirm the Company’s ability to produce a spodumene concentrate that meets market specifications. The heavy liquid separation (HLS) testing employed is a lower-cost and more rapid methodology for testing the applicability of a Dense Media Separation (DMS) process flow sheet,

which is done at a much larger scale and within a continuous process. Flotation testing on the non-magnetic HLS tailings was also included in the process flow sheet to ensure the highest possible lithium recoveries and determine the best course of development for future process test work.
Material for the test was sourced from PQ-sized drill hole BDD-24-022, which penetrated the full thickness of the Beecher pegmatite, and allowed for a variety of sample mineralogies and composites from across the mineralised interval. One-half of the PQ-sized drill core was processed for metallurgical testing. A total of five (5) samples were developed for the program, with test work completed by SGS Canada Inc. at their facility in Lakefield, Ontario. Three samples were developed from continuously cored zones through the Beecher pegmatite, representing high- and low-grade materials, with head grades ranging from 0.65 % Li2O to 1.72% Li2O. The remaining two samples were composited to form representative run-of-mine (ROM) material and averaged 1.10% Li2O.
Samples were crushed to -6.35mm (-1/4”), with the HLS feed screened to remove the fines (- 0.85mm). The HLS test work entailed performing separation at different specific gravity (SG) cut points at set intervals between SG 3.2 and 2.60 to determine ideal SG cut-points for the first (to reject silicate gangue as tailings) and second (concentrate production) passes, which would result in minimal lithium losses and production of on specification concentrate. The findings determined that global lithium recoveries between 45% and 59% were possible from all pegmatites sampled as similar SG cut points between 2.87 and 2.89. The similarity in SG cut point and recoveries indicate that all tested mineralogies have a similar lithium liberation at a crush of -6.35mm, and a strong indication that that all samples can produce on-specification spodumene concentrate under similar DMS operating conditions.
The HLS middlings, and -.85mm bypass fractions were combined and the ground to 100% passing -0.3mm for flotation testing. The flotation flowsheet included several process stages including desliming, magnetic separation, pyrite and mica pre-flotation, alkaline scrubbing, high-density fatty acid conditioning, and spodumene rougher and cleaner flotation. Flotation proved successful in recovering a significant portion of the remainder of the lithium bearing fraction of the materials, with total overall lithium recoveries following both HLS and flotation ranging from 62.9% to 82.3% based on mass balance calculations, with all but one sample achieving mid-70% or higher. Sample 1 was an outlier in flotation recovery and Fe2O3 content due to overall low feed grade and variability in the flotation test process as the first sample run through the program.
Table 1 presents the results of the HLS and flotation testing, including head grades, the recovery of lithium by each of the two major process stages in the flow sheet.
Overall, the completed metallurgical test work has provided very positive results for the Beecher pegmatite, with lithium recovery yields for high-grade material in excess of 82%, and test work has demonstrated the Company’s ability to produce a high-purity 6% Li2O spodumene concentrate. Furthermore, the combined HLS and flotation performance with the composite samples confirmed strong amenability to a hybrid DMS and flotation flowsheet for average ROM materials, with overall lithium recoveries of 77% and 80% at concentrate grades of 6.06% and 6.32% Li2O with <1.0% Fe2O3. These results exceed current market specifications for 6% Li2O spodumene concentrate (SC6), which require <1.3% Fe2O3.
IRIS is now planning the next steps in development of the process flowsheet that will be successful across the multiple spodumene bearing pegmatite bodies to support a “hub and

spoke” operations model for the Company’s South Dakota projects. IRIS anticipates testing of additional pegmatites at the Beecher Project and the Tin Mountain Project, as work also proceeds on developing a demonstration mining program and bulk sample collection at the Beecher Project.
In addition, IRIS is currently investigating paths to refine spodumene concentrate from its projects into lithium carbonate or lithium hydroxide within the United States. Now that the Company has spodumene concentrate samples in house, it is expected that testing with potential processing partners will occur in the near future.

IRIS Metals has secured mining permits covering the entire Beecher Project, allowing mining operations to commence at the company’s discretion. The Project’s location provides excellent infrastructure, including nearby road, rail, and power, in a mining-friendly jurisdiction within one of the most significant and largest lithium markets in the world. Recognising lithium as a critical mineral, the US government is offering substantial financial support to bolster local supply and reduce reliance on international sources.
Additional Ongoing Activities
The IRIS technical team has expanded exploration efforts across a large portion of the Company’s South Dakota project areas.
IRIS recently commenced drilling operations at the Tin Mountain Project, with activities there continuing through the fall. Site preparation continues at the Edison Project, with exploration permitting advancing in anticipation of commencing a drill program there in 2025.
Comprehensive regional exploration activities, focusing on geologic mapping and gridded soil surveys, are underway across the Company’s extensive mineral holdings. These efforts aim to identify promising targets on Federal mineral claims for future drilling.
Once identified, the targets will be prioritised, and the drill permit process will commence to ensure a steady workflow. IRIS will report on this workflow once sufficient data has been generated to support interpretations and subsequent decisions.
About The South Dakota Project
The Black Hills of South Dakota are famous for historic lithium mining dating back to 1898 when Li-bearing spodumene, and amblygonite was first mined near the township of Custer. IRIS has staked 2,387 federal mineral claims and has agreements over two patented claim blocks.
Existing project areas include:
-
➢ Beecher Project – including Longview and Black Diamond
-
➢ Tin Mountain
-
➢ Edison Project
-
➢ Helen Beryl Project
-
➢ Tinton Project
-
➢ Keystone Project
The Beecher pegmatite trend was mined sporadically between the 1920’s and 1950’s for lithium, beryllium, tantalum, mica and feldspar. Limited amounts of lithium spodumene ore from the Beecher mines was shipped to Hill City during the 1940’s where it was processed through a flotation circuit.
IRIS’ local partner has been granted mining licenses permitting lithium pegmatite mining for these patented claims.
These mining licenses, permitted by the State of South Dakota, enable IRIS to fast-track all exploration and mining activities including the right to explore and mine lithium bearing pegmatites.
