ASX ANNOUNCEMENT - 20TH MAY 2020
Sultan Resources Limited (ASX: SLZ) ( Sultan or Company ) is pleased to announce results from the first batch of soil and rock chip sampling returned from ongoing exploration programs across the Company’s Lachlan Fold Belt (“LFB”) Porphyry Au-Cu projects (see ASX announcement 08/05/2020).
The ongoing exploration program is designed to identify drill targets with high potential to host porphyry-style Au-Cu and/or epithermal gold mineralisation across the three highly prospective targets at Big Hill, Ringaroo and Tucklan. The Company has received results for work undertaken at the first of these projects, Big Hill in the southwest of EL8375.
Significant Results
Geological mapping, soil and rock chip sampling has initially targeted the western flank of the Big Hill magnetic high complex, designed to identify often subtle surface indications of buried porphyry AuCu style mineralisation. Surface features typically associated with this style of mineralisation in the Macquarie Arc include large zoned Au-Cu and key pathfinder surface geochemical anomalism, zoned hydrothermal alteration facies including propylitic and sodic, and litho-geochemical indicators of volcanic arc rock-types ideally coincident with strong magnetic signatures.
The Company is pleased to report results that confirm all of these features, whilst defining three priority targets: Gowan Green, Big Hill and Wattle Ridge.
Jeremy King, Chairman of Sultan Resources commented:
“ Receipt of such outstanding soil and rock chip results within weeks of shareholders approving the acquisition is a timely reward. To have such high grade gold and copper results returned from within new large scale soil anomalies, coincident with the right rock types, porphyry style alteration and mineralisation, all sitting above a large magnetic complex confirms the Big Hill area as one with significant potential ”.
Gowan Green
Lying immediately to the north of Big Hill, the Gowan Green prospect is centred upon a subtle historic gold and copper working showing gossanous malachite-azurite veined, propylitic altered (epidotechlorite-carbonate-albite) mafic volcanic rocks (Figures 1, 2 and 3) in mullock heaps overlying a subtle magnetic high anomaly. Rock samples of this material have returned spectacular results, including:
Table 1: Significant results from the Gowan Green rock samples
| Sample ID | Au g/t | Cu % | Ag g/t | Sample Type |
|---|---|---|---|---|
| SPR020 | 24.6 | 26.1 | 65.5 | Mullock |
| SPR021 | 2.69 | 7.55 | 20.0 | Mullock |
| SPR022 | 0.51 | 4.49 | 7.7 | Mullock |
| SPR023 | 0.35 | 5.96 | 11.7 | Mullock |
| SPR024 | 0.94 | 5.71 | 21.6 | Mullock |
| SPR025 | 0.04 | 10.1 | 7.9 | Mullock |
| SPR026 | 1.16 | 12.55 | 24.8 | Mullock |
The high grade Au-Cu rock chip samples validate a newly defined large (>1.5km x >0.10km), low level Au-Cu + pathfinder soil geochemical anomaly associated with a discrete magnetic high (~300m diameter) anomaly and NE-SW structural corridor (Figure 5). Limestone stratigraphy, possibly forming a cap-rock displays numerous small zones of possible skarn mapped intermittently over a ~600m x ~300m area. Litho-geochemical studies of the multi-element assay data confirm Gowan Green rocks are calc alkaline basalts, with a volcanic arc tectonic signature consistent with being part of the Molong Volcanic Belt, Macquarie Arc. The target is therefore considered highly prospective for the discovery of porphyry related Cu-Au deposits.

Big Hill
The Big Hill target is marked by a large, high amplitude ovoid shaped magnetic high complex traversed by north-west striking structures. Mapping and soil geochemistry has defined a 2.2km x 0.4km target area containing epidote-veined, pervasive propylitic (epidote) altered, feldspar – pyroxene porphyry with significant disseminated & veined native copper and malachite (Figure 4). Rock samples of this material have returned:
Table 2: Significant results from the Big Hill rock samples
| Sample ID | Cu % | Sample_Type |
|---|---|---|
| SPR004 | 1.30 | Float |
| SPR005 | 2.40 | Float |
| SPR006 | 0.17 | Float |
| SPR014 | 2.21 | Float |
| SPR015 | 2.50 | Float |
The pathfinder geochemical signature is associated with localized disseminated pyrite in ‘green rock’ (chlorite-epidote-albite-actinolite-sericite-hematite-carbonate-prehnite-pyrite-magnetite) altered basaltic andesite volcaniclastic breccias. Encouragingly localized zones of hematite-albite ‘reddened’ altered feldspar porphyries and zones of sodic (silica-albite-pyrite) alteration has been observed (Figures 4 & 5) with up to 6.14% sulphur and 9.0% Na2O recorded (Appendix 1, Table of Rock Sample assay results).
The identification of localized sodic alteration, hematite-albite alteration (‘reddening’), disseminated pyrite associated with ‘green rock’ alteration and the distinct pathfinder geochemical signature is consistent with upper or outer parts of an alkalic porphyry Au-Cu system such as the high grade CadiaRidgeway porphyry Au-Cu mine 50km to the south, and the Boda discovery approximately 50kms to the north.

Big Hill Soil Results
Nominal grid 100m x 200m spaced soil sampling across the Big Hill magnetic complex has returned a significant large-scale (2.2km x 0.40km), low level Au-Cu + pathfinder soil geochemical anomaly (Figure 6), which is open to the south east and represents a compelling exploration target. Complementing the rock chip results outlined above, the soil anomaly adds scale to the Big Hill target whilst also encapsulating propylitic and sodic altered basaltic volcaniclastic rocks, lavas and feldspar porphyries, localized zones of disseminated pyrite, epidote veining with secondary copper (native copper, malachite and azurite), magnetite veining and hematite / feldspar veining. All of these features occur above the magnetic high complex interpreted to represent the upper or outer parts of a buried Late Ordovician-Early Silurian intrusive complex hosted in the same rocks as Alkane’s Boda discovery.
A small creek drainage may obscure soil sampling effectiveness between the Gowan Green and Big Hill Au-Cu soil anomalies, making it possible that Big Hill and Gowan Green may be part of the one porphyry system.

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 field during field inspection of the Big Hill porphyry 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.

| located on the Intersection of a major N-S striking arc parallel and NW-SE | ||
| striking cross arc structural corridors, | ||
| 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 | ||
| The Big Hill target eshibits features consistent with an Alkalic intrusive | ||
| complex, with mineralogy & textures typical of the Cadia Intrusive Complex, | ||
| including outcropping monzogabbro, diorite, monzodiorite & mafic | ||
| monzonite porphyry dykes & small plugs or ‘apophyses’. | ||
| Intrusives have intruded interpreted Cadia and Boda equivalent stratigraphy | ||
| being the Late Ordovician Oakdale Volcanics, including an upper volcanic | ||
| dominant and lower volcano-sedimentary package equivalent to the Forest |
