DECEMBER 2021 QUARTERLY ACTIVITIES REPORT

HIGHLIGHTS

Bob's Prospect - Significant Gold System Confirmed 7km East of Apollo Hill

  • Significant Aircore (AC) and follow up Reverse Circulation (RC) results have confirmed a large, concealed gold system, 7km east of the 944,000 oz gold Apollo Hill Mineral Resource (35.9Mt @ 0.8g/t Au1); Figure 2.
  • Results include:
  1. 5m @ 6.82g/t Au from 130m - AHRC0825;
  1. 5m @ 3.15g/t Au from 168m - AHRC0827; and
    1. 32m @ 0.49g/t Au from 68m including 8m @ 1.41g/t Au from 84m - AHAC0349.
  • Drilling results show improving grade vectors, which remain open.
  • Intersections highlight a so far under explored 3.5km long gold system beneath relatively shallow cover (Figure 2) on the eastern side of the Apollo Hill 'Super Structure' (Figure 3).
  • A 4,000m follow up RC drilling program is planned.

Other New Gold Prospects

  • AC results from wide spaced regional exploration drilling, completed towards the end of the 2021 field season have also highlighted three new prospects along strike from the Apollo Hill Mineral Resource.
  • Significant intersections include:
  1. 13m @ 1.32g/t Au from 56m including 4m @ 4.31g/t Au from 56m - AHAC0464 at the Aquarius Prospect (Figure 5);
  1. 12m @ 0.74g/t Au from 48m including 4m @ 1.36g/t Au from 56m - AHAC0444 at the Casper Prospect (Figure 5); and
    1. 4m @ 0.47g/t Au from 44m - AHAC0477 and 8m @ 0.36g/t Au from 44m - AHRC0478 (two holes drilled 400m apart on a single regional drill line) at the Hercules Prospect (Figure 5).
  • Results are located on a major geological corridor that extends from Apollo Hill, highlighting the potential for additional discovery.
  • A 20,000m regional AC drilling program is underway across the greater Apollo Hill land package and assays are pending for approximately 30 holes, totalling 1,500m, completed to date.

Apollo Hill Resource Area - Resource Extension

  • At Apollo Hill Main Lode, RC drilling results continued to develop the mineralisation at the northern extents of the deposit.
  • Thick, shallow intersections included:
    1. 25m @ 0.66g/t Au from 11m - AHRC0821.
  • Mineralisation is an extension of the Apollo Hill hanging-wall zones and further drilling is being planned.
  • A resource upgrade process is underway at Apollo Hill utilising the results of all drilling from the 2021 field season, metallurgical test work and a preliminary engineering cost study currently underway. The update is scheduled for release towards the end of the March 2022 Quarter.

1 Details of the Mineral Resource which currently stands at 35.9 Mt @ 0.8 g/t Au for 944,000 oz Au and a breakdown by category are presented in Table 1a (page 17 of this document) along with the associated Competent Persons statement and details of the ASX announcement that this information was originally published in.

Corporate

Successful Capital Raising

  • In November 2021 the company successfully completed an $8 million share placement to Australian and Overseas institutional and professional investors. The placement was strongly supported by our current major shareholders. Funds are being used to progress exploration and resource development at the Apollo Hill deposit, to deploy camp and regional scale exploration programs and will also be directed towards the West Wyalong gold joint venture in New South Wales.

Strong Cash Position

  • The cash position of the Company at 31 December 2021 was A$10.038M. In addition, the Company expects to receive the balance of the November 2021 placement proceeds, totalling $1.360M (before costs), once a Foreign Investment Review Board approval process is complete in early calendar 2022.

ACTIVITIES

APOLLO HILL RESOURCE AREA

Resource Extension Drilling

During the Quarter, the Company completed an RC drilling program at the Northern end of Apollo Hill to follow up on previous significant results, including 7m @ 11.18g/t Au from 172m and 3m @ 17.62g/t Au from 160m in extensional RC hole AHRC0813. Results recently returned include 25m @ 0.66g/t Au from 11m in AHRC0821 highlighting thick shallow mineralisation on a northerly extension of the Apollo Hill hanging-wall zones. Further drilling is being planned.

This drilling is part of the Company's ongoing strategy to grow the Apollo Hill Mineral Resource, which was upgraded to 944,000 ounces on 28 January 20211. A resource upgrade is planned for early 2022, utilising the results from over 40,000m of drilling completed since January 2021, and results of metallurgical test work and a preliminary engineering cost study currently underway.

Figure 1 shows recent significant results in plan view.

Appendix 1 lists significant intersections and Appendix 2 lists relevant hole details. Results this quarter complement excellent assays reported in 2021 including:

  • 21m @ 1.82g/t Au from 57m - AHRC0646;
  • 8m @ 9.47g/t Au from 102m - AHRC0647;
  • 23m @ 1.74g/t Au from 49m including 8m @ 3.20g/t Au from 53m - AHRC0690;
  • 10m @ 4.00g/t Au from 89m - AHRC0766; and
  • 21m @ 1.81g/t Au from 44m - AHRC0769.

Metallurgical Test work

During the Quarter, the Company submitted 600m of large diameter (PQ and HQ sized) diamond drill core to the laboratory for a series of metallurgical tests designed to evaluate the amenability of Apollo Hill mineralised material to bulk tonnage, low operating cost processing methods such as heap or vat leaching.

Results from preliminary test work reported in the last quarter showed clear potential to consider lower processing costs through simpler and scalable treatment options. Lower unit costs can in turn lead to lower cut off grades allowing the processing of additional mineralised material, improved stripping ratios, more efficient mining processes and economies of scale.

Material was submitted from differing geographies, material types, grade ranges and rock types at Apollo Hill. Specific test programs conducted in site water are focussing on:

  • Rock strength and crushing and grinding characteristics;
  • Agglomeration and permeability tests;
  • Leach testing via bottle roll for overall recovery at various crush sizes; and
  • Bigger scale column leach testing to help assess leaching kinetics under conditions more closely reflecting full scale operations.

Costs Study

During the Quarter, the Company commissioned a preliminary capital and operating costs study for large scale, bulk tonnage processing at Apollo Hill. The engineering firm engaged to conduct the study has significant experience in this style of operation and are the design engineers for a similar project currently under construction in Western Australia. The study is expected to deliver up to date and locally based cost information which will provide a sound basis for assessing Apollo Hill's project development options.

Resource Update

The results of Saturn's successful 2021 drilling campaign are being integrated into a new mineral resource block model. This block model will be used with results of the costs study and the new metallurgical data (both due in February/March) to provide important cost and recovery information for open pit optimisation studies and the subsequent resource upgrade, planned for release at the end of the first Quarter of 2022.
