STEAM ENGINE GOLD DEPOSIT (GREENVALE PROJECT)
Most of the operational activities during the reporting period were focussed on the Steam Engine Gold Deposit, which is located within the Company’s greater Greenvale Project (Figures 1 and 2). The work comprised:
-
Resource infill and expansion drilling at the Steam Engine and Eastern Ridge lodes;
-
Mineral Resource Estimation modelling;
-
Scoping Study evaluation programs; and
-
Detailed field investigation and mapping of the new Dinner Creek Lode.
The activities at the Steam Engine Gold Deposit are undertaken for the purpose of assessing the potential for a near-term mining and toll treatment operation at the Project. The programs were commenced during the 2020 September Quarter with the release of an upgraded Mineral Resource Estimate ( MRE ) and a Stage 1 drilling program.
A second Revised Mineral Resource Estimate (based on the Stage 1 drill results) and a Stage 2 drilling program were completed during the December Quarter.
Stage 1 Drilling Program
The Stage 1 drilling program commenced during late July 2020 and was completed on 18 September 2020. The program totalled 3,756 metres from 73 drill holes as follows:
-
65 reverse circulation ( RC ) drill holes for 3,059 metres;
-
6 shallow diamond core holes for 302 metres; and
-
2 deeper RC/diamond tailed drill holes for 395 metres.
Assay results from the Stage 1 program were incorporated into the Resource dataset for the purpose of developing a revised Mineral Resource Estimate, which was published on 14 December 2020.
All Stage 1 resource and exploratory holes intersected mineralised lode with the majority of intersections reporting high grade gold. All assay results from the Stage 1 drilling program were received from SGS Australia geochemistry laboratories in Townsville by early November 2020.
A range of typical intersections include[1] :
-
18m @ 2.4 g/t Au from 21m (SDD006)
oincl 6m @ 4.6 g/t Au from 33m -

Stage 2 Drilling Program
A Stage 2 drilling program comprising a total of 40 reverse circulation ( RC ) drill holes for 3,055 metres, commenced on 11 November 2020 and was completed on 12 December 2020. Drill hole depths ranged from 48 to 120 metres.
The objectives of the Stage 2 program were to:
-
extend high-grade zones identified during the Stage 1 program beyond the current Resource envelope;
-
identify new high-grade extensions at both the Steam Engine and Eastern Ridge lodes;
-
upgrade low-grade zones within the current Resource envelope; and
-
increase the Measured and Indicated Resource categories.
The first reportable batch of assays from Stage 2 were received in early January 2021. These results were from 15 of the 40 Stage 2 program holes. The remaining 25 holes are designed to extend the mineralisation envelope at the Steam Engine and Eastern Ridge Lodes and identify additional high grade ore shoots. Results for these holes are yet to be received.
The Stage 2 drilling results will be incorporated into a planned Pre-Feasibility Study, which will commence immediately after the delivery of the Steam Engine Project Scoping Study, expected in early February 2021.
Assay results from the first 15 drill holes were reported to the market on 18 January 2021. These holes were designed to target a large modelled low-grade zone of the Revised Mineral Resource (reported to the ASX on 14 December 2020; refer below) and were designed to upgrade the zone.
The 15 infill holes successfully fulfilled the design objective and resulted in the conversion of the low grade zone to become the highest grade zone within the Steam Engine Lode. The outcome was assisted by spectacular assay results of up to 184 g/t Au that were reported from two adjacent drill holes[3] :
-
5m @ 38 g/t Au from 49m (SRC077)
-
incl 1m @ 184 g/t Au from 51m
-
7m @ 20.6 g/t Au from 54m (SRC076)
-
incl 1m @ 135 g/t Au from 55m
The very high grades reported in holes SRC076 and SRC077 are on adjacent lines and are located directly down dip of the ounce per tonne intersection reported from the Stage 1 Program. The three ounce-plus per tonne intersections, together with other adjacent intersections define a very high grade ore shoot within a low-grade zone that was modelled in the Revised Mineral Resource Estimate[4] (Figures 3 to 5).
Such very high-grade zones will contribute to significantly raise the total ounces in the deposit. As a result, further drilling on this portion of the Resource will be conducted in order to delineate extensions to the high grade ore shoot.
The results from the Stage 2 drilling program have not been factored into the December 2020 Revised Mineral Resource Estimate, but will be included in a Pre-feasibility Study that will immediately follow the completion of soon to be released Scoping Study.

Revised Mineral Resource Estimate
The Steam Engine Project Mineral Resource Estimate ( MRE ) was revised on the basis of the results from the Stage 1 drilling program.
The revised MRE resulted in a 19% increase in total contained gold and a 26% increase in total Resource tonnes and now stands at (refer Figures 6 and 7; Tables 1 and 2):
-
1.6 million tonnes at 2.2 g/t Au (approximately 112,000 ounces) , including:
-
Measured and Indicated Resources: 650,000 tonnes @ 2.4 g/t Au (approx. 51,000 ounces) ; and
-
Inferred Resources: 950,000 tonnes @ 2.0 g/t gold (approx. 61,000 ounces)[5] .
The purpose of the revised MRE was to increase the geological confidence of shallow portions of the previous Mineral Resource. The revision also enables the completion of the Scoping Study and progression to a Pre-feasibility Study.
Mineralisation within the Steam Engine and Eastern Ridge lodes remains open along strike and down dip. The Stage 2 drilling program has targeted these areas to further expand and upgrade the Mineral Resource.

New Dinner Creek Lode
As a result of detailed geological mapping and rock chip sampling, an extensive zone of gold mineralisation was delineated approximately 900 metres to the east of the Eastern Ridge Lode. This zone of mineralisation has been named the Dinner Creek Lode (Figure 8).
Field geological observations noted that gold-bearing rock outcrops at the Dinner Creek Lode appear to be a similar rock unit with similar alteration style to the Steam Engine Lode. The Dinner Creek Lode is notably thicker at surface compared to the Steam Engine and Eastern Creek lodes and is potentially longer in strike length.
The Dinner Creek Lode has not been subjected to any modern or historical drilling, despite appearing at surface to be the longest and thickest lode zone.
A high priority maiden drilling program will commence immediately after the end of the current northern Australian monsoon season.

Rock Chip samples from Dinner Creek Lode
Rock chip samples taken from the alteration zone returned up to 7.6 g/t gold, which complements historically reported rock chip assays of 4.3 g/t and 3.6 g/t gold.
The alteration zone is a gossanous, strongly brecciated zone within a zone of gossanous sericitic-quartz alteration that has previously been mapped by Pancontinental Resources during 1993 to 1994. This zone is located within the Eland Metavolcanics, some two kilometres south-east of the Steam Engine Lode zone and some 4 kilometres north of the Bottletree porphyry copper zone.
The strongly brecciated zone has been mapped by the Company and is approximately 2 kilometres in strike length.
A sphalerite sample collected from the area was sent off to the CSIRO for lead isotope analysis and was reported by Pancontinental to be consistent with a primitive signature similar to that observed from the rocks hosting Cu-Au mineralisation in the Lachlan fold belt of NSW.
BIG MAG AND GREENVALE NICKEL POTENTIAL (GREENVALE PROJECT)
Desktop data review, land access preparations and initial exploration program planning was conducted during the Quarter on the Big Mag Prospect as well as the greater Greenvale Project area for its potential to host magmatic nickel sulphide deposits. The area has been a significant source of nickel production, notably at the Old Greenvale Nickel Mine which produced approximately $6b nickel at current prices.
Big Mag is a regionally large and intense magnetic feature that appears to be a large mafic or ultramafic intrusion, or several such intrusions. Consequently, it has the potential to host nickel-cobalt-copper mineralisation, either as sulphides or in a laterite weathering profile. The Company is of the view that the Big Mag feature is developed within the same geological sequence as the “old” Greenvale Nickel Mine” (now part of the SCONI Project).
The Big Mag magnetic feature is regionally significant and under-explored and is covered by a recently granted exploration permit (EPM26751, Twelve Mile Creek) (Figure 2).
Additionally, two new exploration permit for minerals ( EPM ) applications were submitted (Dido and Arthur Range Projects) covering substantial areas that are prospective for Voisey’s Bay style magmatic nickel-copper-cobalt-PGE deposits (Figure 2).
WYANDOTTE (GREENVALE PROJECT)
The Wyandotte Prospect is a shallow zone of high-grade copper mineralisation, which is potentially associated with a deeper intrusion-related or porphyry system.
Historic drilling has targeted the copper mineralisation. However, there has been insufficient drilling to estimate a reportable Mineral Resource.
A technical study of the existing data continued during the Quarter in order to establish an exploration target to determine whether potential exists for expansion of the copper mineralisation.
The results of this study will be published shortly. A program of drilling and mining studies is planned to commence early in 2021.
