Significant Results - Tucklan
Geological mapping, soil and rock chip sampling has initially targeted a prominent magnetic feature coincident with a strong potassium radiometric anomaly and a line of historic gold workings.
Soil Sampling
Soil sampling across a 100m x 100m grid has defined a 1.5km x 0.30km, NW-SE striking, coherent gold in soil geochemical anomaly showing gold values consistently greater than 7.2ppb Au. A higher grade 700m x 300m Au soil anomaly ‘core’ is evident with values up to 613ppb Au in soil returned. The gold in soil anomaly is open to the southeast (Figure 2).
Semi-coincident with the gold in soil anomaly is a series of zoned pathfinder soil geochemical anomalies that are indicative of a large scale, zoned hydrothermal gold system. Complex metal zonation includes Au-As-Sb-Hg-Ba-Ag-Se-Te in the southeast, Au-W-Ag-Cd-Pb ±Hg-Ba-Te-Se in the northwest, Au-Pb-Cd-Ag-Tl in the east and a well-defined arcuate Cu-Zn-Co zone across the centre.
Historical gold workings are associated with the gold in soil anomaly and include numerous prospecting pits and a shallow shaft and adit. These form part of the under-explored and extensive historic Tucklan Goldfield. The large-scale gold and pathfinder surface geochemical anomaly is spatially associated with a 3.5km x 2.5km magnetic high complex (Figure 2) and 1.8km x 0.5km NW-SE striking potassium radiometric anomaly (Figure 3).

Rock Samples
First pass rock chip sampling on the margins of the gold and pathfinder soil anomaly has confirmed the presence of strongly anomalous gold and pathfinder elements such as As-W-Tl-Ba-K-S ±Ag-Cu-Mo. Significant gold rock chip results in pervasively altered volcanic rocks include 1.11g/t Au, 0.25g/t Au, 0.14g/t Au, 0.48g/t Au, 0.27g/t Au and support the strong prospectivity of the Tucklan Project.

ASX ANNOUNCEMENT – 2[ND] JUNE 2020
The gold rich rock chip samples are associated with widespread disseminated pyrite in pervasive silicaK-feldspar (adularia*) - white mica-jarosite-kaolinite-gypsum-pyrite altered, polymict breccias or volcaniclastic sandstones, with pyrite veining and localised quartz±sulphide stockwork veining (Figures 1 and 4).

Lithogeochemical Studies
Immobile element lithogeochemistry plots characterise the hydrothermally altered host rocks as trachy-andesite to alkali basaltic volcano-sedimentary rocks and indicate they are part of the Late Ordovician – Early Silurian Tucklan Formation of the Rockley - Gulgong Volcanic Belt of the Macquarie Arc. The Tucklan Formation is interpreted to be synchronous with Phase 4 volcanism in the Macquarie Arc which is associated temporally with the largest porphyry Au-Cu deposits in the belt. The Tucklan gold target is just ~45km to the NE of Alkane’s recent Boda Au-Cu alkalic porphyry discovery.
Lithogeochemical alteration studies have confirmed the rocks have undergone significant potassium metasomatism, with the likely presence of significant K feldspar (adularia*) and white mica alteration. The rocks have also undergone sodium and calcium depletion. Terra Spec SWIR hyperspectral data confirms the white mica is predominately NH4 (ammonium) white mica with minor phengite & muscovitic phengite (Appendix 2). Significant jarosite, kaolinite & gypsum has also been identified. Ammonium (NH4) white mica has been documented as an alteration halo mineral to various gold deposits, including the high-grade Waihi epithermal gold veins in New Zealand.
*To be confirmed by petrological studies and /or k-feldspar staining
Future Work Program - Tucklan
The Tucklan geology and geochemistry are consistent with characteristics associated with several ore deposit models, such as volcanic hosted epithermal gold systems or gold rich VHMS (volcanic hosted massive sulphide) systems. In addition, high potential remains nearby and at depth for the presence of porphyry Au-Cu-Mo deposits.

ASX ANNOUNCEMENT – 2[ND] JUNE 2020
The high priority Tucklan gold target remains undrilled. Several high priority magnetic highs and lows associated with arc-parallel and NW-SE cross-arc structural corridors remain unexplored Figures 5 & 6). Follow up exploration including geological mapping, further rock and soil sampling, petrology, high resolution IP surveys are planned with a view to delineating sites for extensive drill testing.

Lachlan Fold Belt Exploration Programme – Other Prospects
Big Hill
Follow up exploration at Big Hill will continue in the next quarter with
-
high resolution ground IP surveying designed to locate chargeability features (pyrite halos) coincident with the multidisciplinary surface anomalism, and
-
Ongoing geochemical sampling and mapping to the east of the current soil anomaly to test the remainder of the magnetic complex.
For further information on Big Hill and its outstanding initial groundwork results, please see the Company’s announcement dated 20 May 2020.
Ringaroo
A soil and rock chip sampling campaign has commenced at the Ringaroo porphyry Cu-Au target in the north of EL8735. The Ringaroo target is located directly along strike to the south of Impact Minerals “Apsley” target (ASX Announcement 22/11/2019) where a high amplitude magnetic high anomaly has been defined on Sultan’s tenure.
With over $2m cash, Sultan is well placed to continue this activity and fund exploration of these high quality prospects.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
-
Criteria JORC Code explanation Sampling • Nature & quality of sampling (e.g. cut channels, random chips, or specific techniques specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.
-
Include reference to measures taken to ensure sample representivity & the appropriate calibration of any measurement tools or systems used.
-
Aspects of the determination of mineralisation that are Material to the Public Report.
-
In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.
Commentary
Current Rock sampling program
-
Rock chip samples were taken in the during field inspection of the Tucklan gold target
-
Rock samples were collected from surface outcrop and float
-
Outcrop samples are resistant portions of the local geology and are considered to be in situ. Float samples are interpreted to have been sourced from local area..
-
Samples weighing up to several kilograms were collected
Current soil sampling program
- All soil sample points were located using a hand-held GPS with +/-5m accuracy utilising MGA zone 55 (GDA94) coordinate system. Surface organic matter was removed from the sample site using a hand pick and shovel and a 25cm x 25cm x 25cm deep hole was dug using a mattock, with a sample of primarily B soil horizon collected. The soil sample was screened using a 3mm mesh aluminium sieve and a 200-250 gram sub sample of -3mm fraction was retained in a labelled soil geochemical bag for analysis. Soil sample IDs and locations are stored digitally in a register which also notes sample content and conditions. External certified reference material / standards, blanks and duplicates are submitted every 50th, 51st and 52nd sample respectively for QAQC purposes.

| with historical gold workings that include numerous prospecting pits, plus a | ||
| shallow shaft and adit. These form part of the overlooked & extensive Tucklan | ||
| gold field. | ||
| The Lachlan Orogen is approximately 700 km wide and 1000 km long and has | ||
| disputed complex evolutionary history. The Macquarie Arc is part of the | ||
| eastern sub-province of the Lachlan Orogen and is the host to numerous | ||
| porphyry Au–Cu deposits. It consists mainly of subduction-related Ordovician | ||
| intermediate and mafic volcanic, volcaniclastic and associated intrusive rocks | ||
| and was accreted to Gondwana in the Early Silurian, and underwent rifting | ||
| and burial in the Middle to Late Silurian. | ||
| It consists of four structural belts, namely, the western (Junee-Narromine), | ||
| the central (Molong), the eastern (Rockley-Gulgong) Belt, and southern | ||
| (Kiandra) volcanic belts. These belts have most likely been formed by rifting | ||
| and dismemberment of a single arc, which developed along the boundary | ||
| between the Australian and proto-Pacific plates during the Ordovician and | ||
| was subsequently dismembered during the Silurian. | ||
| An entirely intra-oceanic setting is postulated for the Macquarie Arc | ||
| (Crawford et al., 2007), with four phases of arc-type magmatism, the earliest | ||
| in the Early Ordovician, and culminating in the Late Ordovician to Early | ||
| Silurian. The four phases of volcanism in the Macquarie Arc relate to distinct | ||
| groups of porphyritic intrusions that vary from monzodiorite-diorite through | ||
| monzonite-granodiorite compositions and correspond with porphyry copper- | ||
| gold and epithermal gold-silver mineralisation | ||
| Lithology | ||
