Feasibility Study progressing on a low capex operation generating near-term cashflow
Superior Resources Limited ( ASX:SPQ ) ( Superior , the Company ) announced today a further boost for its emerging Steam Engine Gold Project following the latest batch of assay results. The drilling program is part of the Company’s 13,000m drilling campaign underway at its 100%-owned Greenvale Project, located approximately 210kms west of Townsville, Queensland (Figures 1 and 2).
The latest results from 15 RC holes drilled into the Steam Engine Lode confirm the down-dip strengthening of the lode, a development that has been observed over substantial portions of the Steam Engine Lode.
Importantly, the intersections are located predominantly outside the current Mineral Resource of 1.73 million tonnes grading 2.2 g/t Au for 122,000 ounces of gold[1] , which was based on the 2020 drilling program.

Superior’s Managing Director, Peter Hwang commented:
“Once again, the results continue to firm up the project’s potential at depth and along strike. The confidence provided by this year’s drilling program has enabled us to commit to an even larger follow-up program aimed at aggressively expanding the mineralisation envelope.
“Of the almost 15,000 metres of Resource drilling that has been completed since mid-2020, most were infill holes aimed at upgrading confidence levels of shallow parts of the Steam Engine and Eastern Ridge lodes. Having achieved that objective, we will now focus on expanding the mineralisation envelope to realise the potential of the Steam Engine and Eastern Ridge lodes. At surface, these lodes have a combined strike length of at least 2.5 kilometres, of which, only about 15% has been tested to any depths greater than about 50m.
“In addition, we will also target the significant potential that exists in the Southern Zone Lodes and the two-kilometre-long Dinner Creek Lode. The southern extents of most of the lode zones are obscured by thin Tertiary cover. Surface soil geochemistry indicates the potential for extensions of the lodes beneath the cover as well as the existence of new lode zones west and south of the current lodes. We are planning to drill each of these target zones in the next program.
“In the meantime, we are progressing with a revision of the Mineral Resource Estimate as well as preparing a maiden Ore Reserve. With the continued positive developments from this year’s Resource drilling program together with the recent strengthening of gold price forecasts, we are also undertaking further financial modelling to reassess the project’s development strategy.
“This process will examine the merits and timing of establishing a scalable processing plant against haulage and toll-treatment pathways, optimal Mineral Resource targets and other key financial factors.”
The latest results at Steam Engine follow the spectacular intersection grading 115.2 g/t Au from its Eastern Ridge Lode, announced in October (refer ASX release 18 October 2021), among other positive drilling results in 2021.
Superior aims to develop a low capex mining operation at Steam Engine, with the potential for near-term cashflow to drive increased shareholder value and support the Company’s other high-potential Queensland projects, including the Bottletree Copper Prospect.
Assay Results – 5[th] Batch
Results have been received from 15 reverse-circulation ( RC ) drill holes (SRC175 to SRC189) at the Steam Engine Lode (Table 1).
The holes targeted predominantly deeper portions of the main Steam Engine Lode. The drilling has shown considerable potential for increasingly deeper portions of the Steam Engine Lode to contain substantially greater thicknesses of gold mineralisation. The results confirm that good potential exists for significant expansion of the Mineral Resource and that further down-dip drilling of the lode should also be continued to outline the extent of underground potential at Steam Engine. The mineralisation remains open at depth.
The current depth extents to which the Steam Engine Lode has been drilled is considered to be relatively shallow and considerable potential exists to incorporate deeper Mineral Resources into a larger open-cut pit.
Significant results include SRC188 with 21 metres @ 2.2 g/t Au from 160 metres downhole (including 5m @ 5.1 g/t), SRC175 with 8 metres @ 2.8 g/t from 154m downhole (including 1m @ 6.7 g/t), SRC183 with 9 metres @ 3.0 g/t Au from 173 metres downhole (including 1m @ 10.7 g/t), SRC176 with 7 metres @ 2.7 g/t Au from 118 metres downhole (including 2m @ 5.6 g/t), SRC178 with 7 metres @ 2.4 g/t Au from 76 metres downhole (including 1m @ 8.1 g/t) and SRC177 with 8 metres @ 2.2 g/t from 126 metres downhole (Table 1).

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section)
| Criteria | JORC Code explanation | Commentary | Commentary |
|---|---|---|---|
| Mineral | • Type, reference name/number, location and ownership including | • |
The areas reported for the Steam Engine Project lie within Exploration Permit for |
| tenement and | agreements or material issues with third parties such as joint | Minerals 26165, which is held 100% by Superior Resources. | |

| Resources to operate on the tenements. | |||
| Exploration | • Acknowledgment and appraisal of exploration by other parties. | • | All historical drilling reported in this report has been completed and reported in |
| done by other | accordance with their current regulatory regime. | ||
| parties | • | Compilation in digital form and interpretation of the results of that work in digital form | |
| has been completed by a Competent Person. | |||
| Geology | • Deposit type, geological setting and style of mineralisation. | • | The Steam Engine and Eastern Ridge gold deposits are hosted within shear zones. |
| • | Gold is mineralised within a number of north-northeast trending, west-dipping pyritic | ||
| quartz-muscovite-carbonate schist lodes within metamorphosed intermediate to basic | |||
| intrusives and metasediments. Significant chlorite–epidote and sericite type alteration | |||
| zones exist in the shear zones with the mineralisation appearing to be mostly | |||
| associated with heavily sericite altered sections of the host rock. | |||
| • | The gold mineralisation phase consists of a predominant pyrite sulphide assemblage | ||
| +/- minor arsenopryrite, pyrrhotite, and chalcopyrite (all fine grained). | |||
| • | Several gold bearing lodes occur in the area, of which the Steam Engine Lode zone is | ||
| the most notable. The Eastern Ridge Lode zone is located some 500m east of the | |||
| Steam Engine Lode zone. The Southern Lode zone is located approximately 600m | |||
| Southwest of the current Eastern Ridge Mineral Resource area and lies geologically | |||
| between the Steam Engine and Eastern Ridge lodes. The Dinner Creek shear zone is |

|---|---|---|---|
| located some 2 kilometres south-east of the Steam Engine Lode zone and has very | |||
| similar looking mineralisation and alteration to the Steam Engine Lode. | |||
| • | The lodes are typically interpreted as being of the mesothermal lode type. Recent | ||
| studies undertaken by Superior Resources suggest the Steam Engine mesothermal gold | |||
| mineralisation is orogenic style mineralisation. | |||
| • | Important features of the lodes are their continuity and a persistent dip to the west. | ||
| Drill hole | • A summary of all information material to the understanding of | • | Drill hole collar and significant intersection tables are included in the main body of the |
| Information | the exploration results including a tabulation of the following | report. These tables include information relevant to an understanding of the results | |
| information for all Material drill holes: | reported. | ||
o easting and northing of the drill hole collar |
|||
o elevation or RL (Reduced Level) of the drill hole collar |
|||
o dip and azimuth of the hole |
|||
o down hole length and interception depth |
|||
o hole length. |
|||
| • If the exclusion of this information is justified on the basis that | |||
| the information is not Material and this exclusion does not | |||
| detract from the understanding of the report, the Competent | |||
| Person should clearly explain why this is the case. | |||
| Data | • In reporting Exploration Results, weighting averaging | • | Exploration results are reported as a length weighted average of all the assays of the |
| aggregation | techniques, maximum and/or minimum grade truncations (e.g. | hole intersections. | |
| methods | cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some |
• | No top cutting has been applied to the exploration results. The recent addition of some ounce/tonne gold grades in some assays in the 2020 and 2021 drilling means that grade cutting of very high values will need to be applied during the resource estimation process. |
| typical examples of such aggregations should be shown in detail. | • |
No metal equivalent values are reported. | |
| • The assumptions used for any reporting of metal equivalent | |||
| values should be clearly stated. | |||
| Relationship | • These relationships are particularly important in the reporting of | • |

| percent respectively. | |||
| • | At this stage, no test work has been done to investigate options to improve the gold | ||
| recovery in the Steam Engine Lode samples. |
