Sultan Resources Limited (ASX: SLZ) ( Sultan or Company ) is pleased to announce that it has completed the first phase of its maiden drill program at its 100% owned Tucklan Gold project in the east Lachlan fold belt, NSW. Core from the initial phase has been logged, and intervals for assay analysis have been dispatched. The Company commenced drill-testing of Induced Polarisation (IP) anomalies beneath strong gold and copper surface geochemistry at the Tucklan project in December 2020 (see ASX Announcement 07/12/2020).
Drilling Program - Tucklan
The initial phase of the maiden drill programme at Tucklan comprised 6 RC percussion holes, including two with diamond drilling tails, for a total of 1,544.3m (Figure 1, Appendix 1). Three holes reached their target depth of ~350m and three holes did not reach planned depth due to excessive ground water. Should assay results warrant, Sultan will return to Tucklan to complete the unfinished holes with diamond tails and drill additional holes into any significant mineralisation plus drill test additional soil geochemical targets. The basement geology at Tucklan has been interpretated as Ordovician Tucklan Formation and Silurian Dungeree Volcanics of the Rockley - Gulgong Volcanic Belt, within the Macquarie Arc. The host rocks are considered to have potential to contain multiple styles of mineralisation including porphyry Cu-Au, epithermal Au and McPhillamy’s-style bulk tonnage Au.

Geological Observations
Logging of the drill chips and core has been very encouraging and revealed broad zones of hydrothermally altered volcaniclastics and coherent volcanic facies that contain multiple generations of veining and sulphide mineralisation in some holes. In particular, hole TRC0001, which tested a strong IP chargeability ‘bullseye’ target, intersected a 136m down hole zone (172m to 308m) of moderate to intense, multi-generational vein sets and associated disseminated, stringer and vein-hosted sulphide mineralisation within volcaniclastic sediments (Figures 2 - 5). Sulphide mineralisation was visually estimated to be at least 1.5% throughout the interval and dominated by pyrite and pyrrhotite though significant sphalerite (Zn-sulphide), galena (Pb-sulphide) and chalcopyrite (Cu-sulphide) were all noted in some veins. Numerous vein sets have been identified and include:
-
Quartz Sulphide Veins
-
Quartz + Pyrrhotite veinlets
-
Quartz + Pyrite veins with chlorite halos
-
Pyrite/pyrrhotite veinlets
-
Quartz-Carbonate-Sulphide veins
-
Quartz + Carbonate + Pyrrhotite/pyrite
-
Quartz-Carbonate-Base Metals Veins
-
Quartz + Carbonate veins with Sphalerite + Galena + Pyrrhotite + Pyrite ± Chalcopyrite

ASX ANNOUNCEMENT – 11[TH] FEBRUARY 2021
The style of veining, sulphides and alteration is not interpreted to be typical of an epithermal gold system and could represent a similar style of mineralisation to the McPhillamy’s Gold Deposit located in a similar geological setting ~130km to the south. The occurrence and volume of pyrite and pyrrhotite are considered sufficient to be responsible for the strong IP chargeability response targeted by TRC0001.

Discussion
From the initial exploration groundwork, the Tucklan prospect was originally considered prospective as an epithermal gold target with some potential for Au-rich VMS mineralisation possible. Characteristics such as a structurally-related magnetic low associated with prominent K-radiometric anomalism, extensive Au+pathfinder element soil geochemistry and coincident IP response elevated Tucklan to a drill-ready status. Field mapping had identified outcropping gold-mineralised rock displaying disseminated sulphides and adularia alteration indicative of a potential epithermal system (see ASX Announcement 02/06/2020). Although three of the 6 initial holes failed to reach their target depth, one hole, TRC0001 did pierce a strong IP ‘bullseye’ anomaly and revealed an impressive array of sulphide rich vein sets hosted in volcaniclastic sediments of a mineralisation type that is reminiscent of the McPhillamy’s Gold Deposit (ASX: RRL).
The McPhillamy’s Gold Project is a bulk tonnage gold deposit containing a total resource of 70Mt @ 1.0g/t for 2.29Moz (see Appendix 2, regisresources.com.au/General/reserves-and-resources.html). McPhillamys is interpreted as an orogenic gold deposit hosted in a shear zone within Silurian dacitic volcaniclastics[1] . Gold mineralisation is associated with a hydrothermal alteration assemblage of
page 4
ASX ANNOUNCEMENT – 11[TH] FEBRUARY 2021
quartz+carbonate(ankerite)+white mica (phengite) +pyrite+/-chalcopyrite+/-pyrrhotite+/-chalcocite+/biotite. Elevated gold grades over 1 g/t are associated with very coarse euhedral pyrite, white mica, quartz and carbonate[1] . McPhillamy’s is marked at the surface by coincident Au+As+Cu+Mo+Pb+Bi soil anomalies within a potassium radiometric anomaly. Pole-dipole IP has revealed a 55mv/v chargeability anomaly coincident with the mineralised shear zone.
Many of the characteristics associated with gold mineralisation at McPhillamy’s can be observed in the core from TRC0001. Table 1, below, provides a comparison of the key features. Although the gold content of veining and alteration intersected in TRC0001 is not yet known, the extensive surface geochemical gold anomaly and presence of gold to over 1g/t in altered pyritic volcanic rocks at surface (see ASX Announcement 02/06/2020) indicates that a gold-fertile hydrothermal system has been operating at Tucklan. The discovery of a McPhillamy’s-style gold system at Tucklan could be a companytransformative event for Sultan.
Assay results are expected towards the end of the March quarter due to the increased exploration activity in NSW and resultant sample backlog at the laboratory.

-
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
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
-
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.

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 Based on the work discussed in this document, the rocks at Tucklan are classified to be of trachy-andesite to alkali basaltic volcano-sedimentary origin. |
