TORO ENERGY LIMITED ASX RELEASE
16 December 2021
only | Further Massive Nickel Sulphides Intersected at Dusty 1 | |
HIGHLIGHTS | ||
• Toro has intersected more massive nickel sulphides at the Dusty 1 massive nickel | ||
sulphide discovery within diamond drill hole TED22 (Figure 1). | ||
use | • Further nickel sulphides also intersected in diamond drill hole TED21. | |
• | Diamond drill hole TED22 intersected a 5.8m thick(downhole) zone of visible nickel | |
sulphides containing lenses of massive nickel sulphides of up to 1.3m thick(downhole) | ||
with nickel sulphide blebs above, starting from 253.4m downhole. | ||
• Hand-heldspot analysis by portable XRF (hh-pXRF)suggeststhat individual lenses of | ||
personal | massive nickel sulphide in TED22 may contain 2.6 - 5.4% Ni (massive sulphide only- | |
see below for further information on hh-pXRF and refer to Appendix 1). | ||
• | Diamond drill hole TED22 targeted a position approximately 20m down-dip to the NE of | |
the massive nickel sulphides intersected in TED07 (see below). | ||
• As disclosed in Toro's ASX announcement of 9 December 2020, in prior drilling TED07 | ||
intersected 9m of nickel sulphides grading 2.07% Ni from 250.9m downhole and | ||
inclusive of 4.5m cumulative of massive nickel sulphide grading 3.91% Ni, 0.34% Cu, | ||
0.13% Co and 0.45 g/t Pt+Pd (laboratory geochemistry). | ||
• TED21, which targeted a position approximately 12m to the SE of the massive nickel | ||
sulphides intersected in TED04 (see below) intersected a 3.7m zone of visible nickel | ||
sulphides overlying massive nickel sulphide banding with a hh-pXRF range of 1.3 -7.4% | ||
Ni (massive nickel sulphide bands only- see below for further information on hh-pXRF | ||
and refer to Appendix 1) from 186m downhole. | ||
For | • As disclosed in Toro's ASX announcement of 1 September 2020, in prior drilling TED04 |
intersected 2.6m grading 3.45% Ni,0.18% Cu, 0.15% Co and 0.388g/t platinum and palladium (Pt+Pd) from 184.5m downhole (laboratory geochemistry).
• TED21 and TED22 provide further evidence that Dusty 1 represents a significant occurrence of massive nickel sulphides within the Dusty Komatiite and is still open at depth and along strike to the NW.
• Geochemical sampling of TED21 and TED22 is currently being completed and assay results will be announced once they are returned, at which point further details of the drill holes will also be available.
Toro Energy Limited (ASX: TOE) ('the Company' or 'Toro') is pleased to announce further positive results from recently completed diamond drilling at the Dusty 1 nickel discovery within the Company's 100% onlyowned Dusty Nickel Project (Figure 2) ('the Project') located in the Yandal Greenstone Belt, some 50km
east of the world class Mt Keith Nickel Deposit (see Figure 3).
Drilling has intersected a 5.8m zone (downhole) of visible nickel sulphides containing lenses of massive nickel sulphides up to 1.3m thick (downhole) from 253.4m downhole, in diamond drill hole TED22 (see Figure 1) and 3.7m of visible nickel sulphides from 186m downhole in diamond drill hole TED21.
For personal use
Figure 1: Lens of massive nickel sulphide intersected in diamond drill hole TED22 at Dusty 1. See text for further details.
Diamond drill hole TED22 targeted a position approximately 20m down-dip to the NE of the massive sulphides intersected in drill hole TED07 (refer to ASX announcement of 9 December 2020) and TED21 targeted a position approximately 12m to the SE of the massive nickel sulphides intersected in TED04 (refer to ASX announcement of 1 September 2020).
In TED22, a 5.8m zone of visible nickel sulphides was intersected from 253.4m downhole, which included lenses of massive nickel sulphide up to 1.3m thick towards the bottom of the zone (Figure 1). The upper section of the nickel sulphide zone contained 'blebby' nickel sulphides interstitial in the serpentinised komatiite host rock.
Hand-held spot analysis of sulphide within the sections of massive sulphide by a portable X-RayFluorescence ('hh-pXRF') instrument suggests local nickel concentrations of between 2.6 and 5.4% Ni (see below and refer to Appendix 1 for caution on hh- pXRF analyses and the instrument's performance against certified standards).
The presence of the blebby nickel sulphides above the massive nickel sulphides was also confirmed using hh-pXRF analysis.

In TED21, a 3.7m zone of visible nickel sulphides, including 'blebs' and 'stringers' overlying massive onlynickel sulphide banding (approximately 0.4m thick downhole) was intersected from 186m downhole.
Analysis of the sulphide within the massive nickel sulphide bands using hh-pXRF suggests the individual bands contain from 1.3 to 7.4% Ni (massive nickel sulphide bands only - see below for further i formation on hh-pXRF and refer to Appendix 1). As with TED22, hh-pXRF analysis has confirmed the presence of the nickel sulphide blebs above the massive sulphide banding in TED21.
Both intersections are hosted at the base of the Dusty komatiite within the Dusty 1 massive nickel sulphide discovery area (Figure 2).
useAll drill holes at Dusty 1 to date have intersected massive nickel sulphides of some description and thickness, and which are now spread over a local area of approximately 50m along strike horizontally and some 100m down-dip to the east along the base of the komatiite.
Diamond drill holes TED21 and TED22 are the first holes drilled at Dusty 1 since TED11 in 2020 (refer
to ASX announcement of 1 September 2021) and the intersections of massive nickel sulphides in personalTED22, down-dip of the massive nickel sulphides in TED07, and the visible nickel sulphides in TED21, long strike from the massive nickel sulphides in TED04, is further evidence that the Dusty 1 discovery
is an area with a significant concentration of komatiite hosted massive nickel sulphide. The nickel sulphide zone remains open at depth and along strike to the NW. The nickel sulphides may also continue up-dip towards the base of the overlying paleochannel.
Geochemical sampling of TED21 and TED22 is underway and assay results will be announced once they are returned, at which point further details of the drill holes will also be available. Due to current unprecedented demand for geochemical analysis it is difficult to estimate return dates for assays with any accuracy.
It is important to note that the nickel concentrations stated in this release do not represent the nickel grade of the drill core because there are some silicate clasts within the massive sulphide sections and therefore the overall grade of the nickel sulphide intersection once assayed will be lower as a consequence. 'Spot' analysis of drill core by hh-pXRFshould be used as a guide only, and is not a substitute for bulk geochemical analysis of drill or rock samples. Appendix 1 contains information on the results of testing
Forthe hh-pXRF against certified reference material and Appendix 2 has all relevant drill hole details.
