MINERAL ASSEMBLAGE RESULTS CONFIRM HIGH ZIRCON CONTENT AT DAMPIER HMS PROJECT
KEY POINTS
- Initial mineral assemblage testwork (QEMSCAN) indicates a high value, zircon-rich mineral assemblage for the Thunderbird deposit
- High in situ zircon content of 0.6% indicated for the high grade (9% HM) central portion of deposit
- Drilling results and mineral assemblage testwork continue to demonstrate Thunderbird has the hallmarks of a Tier 1 zircon deposit
Mineral sands explorer Sheffield Resources ("Sheffield") (ASX:SFX) today announced initial mineral assemblage testwork results from its Dampier heavy mineral sand (HMS) project near Derby in the Kimberley Region of Western Australia, confirming the anticipated high in-situ zircon content of the Thunderbird HMS discovery.
Significantly, the mineral assemblage results indicate a high in situ zircon content of 0.6% for the High Grade domain. This figure is derived from multiplying the average zircon content of 6.6% by the average grade within the High Grade domain of 9.0% HM. The High Grade domain averages 15m thickness over an area of 12km2 and remains open in all directions (see Figure 1 and ASX release dated 19 September 2012).
Managing Director, Bruce McQuitty said the results place Thunderbird in the top tier of zircon deposits worldwide.
"There are few heavy mineral sands deposits of this scale with higher in situ zircon content. The Thunderbird discovery is proving to be both high grade and large scale, presenting an outstanding opportunity for Sheffield to emerge as a major HMS developer."
The mineral assemblages have been determined using QEMSCAN on 35 composited HM samples derived from 14 drill holes. The composites were selected from high, medium and low grade 'domains', corresponding to 5% HM, 2% HM and 1% HM cut-offs, respectively. Averages for the high and medium grade domains are summarised below in Table 1 (see Tables 2-5 for full details).
| Domain | Zircon % | Rutile % | High-TiLeucoxene % | Leucoxene % | AlteredIlmenite % | Ilmenite % | |||
|---|---|---|---|---|---|---|---|---|---|
| HighGrade | 6.6 | 1.0 | 1.2 | 2.3 | 4.5 | 25.5 | |||
| MediumGrade | 7.9 | 1.5 | 1.7 | 3.7 | 9.2 | 25.1 |
Table 1: Averages of Mineral Assemblage Results from High and Medium Grade Domains
TiO2 minerals are defined according to the following ranges: Rutile >98% TiO2; High-Ti Leucoxene 90-98% TiO2; Leucoxene 70-90% TiO2 Altered Ilmenite 60-70% TiO2.; Ilmenite 40-60% TiO2.
For the high and medium grade domains, the initial mineral assemblage averages 7.1% zircon, 1.2% rutile, 1.4% high Ti Leucoxene, 2.9% leucoxene, and 31.7% ilmenite, with the zircon content ranging up to 12.3% in certain sections of the deposit.
These results indicate significant mineralogical variability within the thick, high-grade heavymineral intervals. However, the composite samples were selected from just 14 of the first 71 drill holes for which assay results have been received. Further QEMSCAN analyses will be undertaken once assay results from the remaining 93 holes of the maiden drilling programme have been received.
Composite samples were first screened at 212µm, with the minus 212µm fraction submitted for QEMSCAN analysis. The plus 212 µm fraction contains aggregated heavy mineral grains.
Additional heavy mineral may be liberated from these aggregates by more aggressive scrubbing and attritioning steps prior to concentration. This will be investigated by metallurgical testwork, which is currently underway.
Figure 1: Summary plan of results of the 71 drill holes received to date, showing the 12km2 area containing intersections greater than 5% HM on a greyscale elevation image. Grades within this area average 9.0% HM and the mineralisation averages 15m thickness.
About the Thunderbird Prospect
The Dampier project contains two significant heavy mineral sands prospects: a large, shallow eastern zone, named Thunderbird; and a smaller, deeper western zone, named Argo.
Sheffield's maiden drilling programme tested the Thunderbird prospect over an 8km strike length. The drilling pattern is nominally 500m x 500m at the centre of the target area to 500m x 1,000m at the strike extremities (Figures 1 & 2).
Drill results released to date relate to an area about 5km long by 4km wide (20km2). At a 2% HM cut-off, the main mineralised zone varies in thickness from 4.5m to 43.6m, with an average of 25m. There is a higher-grade core (>5% HM) to the mineralised zone which varies in thickness from 4.5m to 32.5m, with an average thickness of 15m over an area of 12km2. The mineralisation shows excellent continuity and remains open in all directions (Figure 1). It is hosted in fine loose sand, with minor 30-50cm bands of cemented sand and ironstone.
Overburden thickness averages 10m, increasing with the dip of the mineralised unit towards the southwest. Significantly, over half of the mineralisation outlined to date (2.5km across strike) has less than 3m of overburden.
Further information on the Thunderbird prospect is contained in the Company's ASX releases of 7 September 2011, 8 November 2011, 12 July 2012, 3 September 2012 and 19 September 2012.
