Confirms High Scandium Grades at Syerston
Melbourne, Dec 8, 2014 AEST (ABN Newswire) - Clean TeQ Holdings Limited (
ASX:CLQ) is pleased to announce that assessment of recent drilling by Ivanplats Syerston Pty Ltd ("Ivanplats"), completed in August 2014, has revealed exceptional scandium grades in an number of drill holes at the northern section of its exploration license.
The new drill data along with historical Ivanplats drilling is currently being assessed to determine what additional work, including new drilling, may be required to produce a scandium resource at Syerston.
In August 2014 Ivanplats Syerston Pty Ltd completed a 14 hole shallow vertical reverse circulation drill program in the vicinity of the old Syerston homestead. The area is south trending from neighbouring licenses on which high scandium grades were previously reported. Best Intersections from the Ivanplats August 2014 drilling program include:
- Hole SRC1272 20m @ 606ppm (6 to 26m) inc: 4m @ 921ppm Sc
- Hole SRC1275 16m @ 541ppm (6 to 22m) inc: 4m @ 922ppm Sc
- Hole SRC1276 16m @ 605ppm (2 to 18m) inc: 4m @ 928ppm Sc (and/or 2m @ 1070ppm Sc)
(Calculated with 300ppm cut-off - Borate Fusion Sc analysis)
The scandium levels are considered very high and are quite shallow, being primarily contained in a laterite soil developed over ultramafic rocks. The laterite also contains significant nickel and cobalt mineralisation, which has been the primary focus of previous development studies.
The head of Clean TeQ Metals division, Mr John Carr, commented: "The drill results confirm that the Syerston project is a rare geological anomaly, hosting some of the highest naturally occurring grades of scandium mineralisation in the world. As a rare earth mineral with significant functional properties for the next generation of light weight industrial alloys and fuels cells, our focus will be to apply Clean TeQ's intellectual property and extensive experience in hydrometallurgical extraction of scandium to build a long-term and stable source of mineable scandium."
As announced on 24 November 2014, Clean TeQ has agreed to acquire the Syerston Project from a wholly owned subsidiary of Ivanhoe Mines Ltd (TSX: IVN). The acquisition remains subject to a number of conditions precedent, including government approval for the transfer and Clean TeQ shareholder approval. The acquisition is a significant first step in implementing the Board's strategy to build Clean TeQ's metal recovery business by identifying and securing projects which are able to benefit significantly from Clean TeQ's unique hydrometallurgical processing capability.
This recent data will be combined with extensive historic drill data from Ivanplats and Black Range Minerals to outline an in-fill drilling program and to establish a maiden scandium resource early in 2015.
Ivanplats completed a 14 hole shallow RC drill program on the Syerston Project in early August 2014, targeting laterites developed over ultramafics in the area. Assays for scandium returned significant results in six of the fourteen holes clustered in an area on the northern boundary of previous drilling campaigns. The six holes had a lateral strike length of approximately 1,000 metres in east west direction.
The scandium results from the six holes are tabled below. Intersections have been calculated using a 300ppm cut-off with no internal dilution, utilising two separate assay methods. Some higher grade individual intersections have been averaged out in these results, however a number of significant higher grade zones are also noted.
- SRC1269 - 22m @ 477ppm Sc (02 to 24m) (Analytical Method - Borate Fusion)
or - 22m @ 428ppm Sc (02 to 22m) (Analytical Method - 4 Acid ICP-MS)
- SRC1271 - 12m @ 572ppm Sc ( 0 to 12m) inc. 2m @ 832ppm Sc (Analytical Method - Borate Fusion)
or - 10m @ 519ppm Sc (02 to 12m) (Analytical Method - 4 Acid ICP-MS)
- SRC1272 - 20m @ 606ppm Sc (06 to 26m) inc. 4m @ 921ppm Sc (Analytical Method - Borate Fusion)
or - 14m @ 512ppm Sc (12 to 26m) (Analytical Method - 4 Acid ICP-MS)
- SRC1273 - 16m @ 523ppm Sc (14 to 26m) (Analytical Method - Borate Fusion)
or - 16m @ 479ppm Sc (14 to 26m) (Analytical Method - 4 Acid ICP-MS)
- SRC1275 - 16m @ 541ppm Sc (06 to 22m) inc. 4m @ 922ppm Sc (Analytical Method - Borate Fusion)
or - 10m @ 438ppm Sc (10 to 22m) (Analytical Method - 4 Acid ICP-MS)
- SRC1276 - 16m @ 605ppm Sc (02 to 18m) inc. 4m @ 928ppm Sc (Analytical Method - Borate Fusion)
or - 10m @ 650ppm Sc (08 to 18m) (Analytical Method - 4 Acid ICP-MS)
Drilling Procedures, Sampling, Analysis, Quality Control/Quality Assurance (QA/QC)
A Halco 1200 drill rig was used for the reverse circulation (RC) drill program provided by Drillit Drillers who operate from nearby town of Parkes.
Two meter samples were collected using a riffle splitter on the drill rig then sent to ALS in Brisbane via preparation lab in Orange to be assayed using both ICP-MS and Borate Fusion analytical techniques. Both Techniques were used to assess any differences in the scandium results for future reference and to assist with interpretation of historical drill results. One fully certified scandium standard and two identical duplicates per hole were also assayed for QA-QC purposes.
Initial examination of QA/QC results did not indicate any significant problems with assaying. However, there were slight differences in the reported scandium levels between the ICP-MS and Borate Fusion analytical techniques, with the ICP-MS giving slightly lower results.
