Tucklan gold drilling on track for end of the month -- local harvest commenced
Sultan Resources Limited (ASX: SLZ) ( Sultan or Company ) is pleased to announce results from ground Induced Polarisation (I.P.) survey undertaken across the Ringaroo Project (EL8735) within the Company’s emerging Lachlan Fold Belt (“LFB”) Porphyry Au-Cu projects (ASX Announcement 08/05/2020). The survey was completed over the previously identified gold and copper anomalous magnetic-high complex located approximately 8km south of Wellington in central NSW (see ASX Announcement 09/07/2020)
The ongoing exploration program is designed to identify drill targets with high potential to host porphyry-style Au-Cu mineralisation across EL8735 – Star Plateau.
IP Results - Ringaroo
During August and September 2020, Fender Geophysics completed 2 north-south lines and 1 eastwest line of dipole-dipole IP surveying across the Ringaroo magnetic high feature that is coincident with a large-scale gold and copper soil geochemical anomaly (Figure 1, see ASX Announcement 09/07/2020). All results have now been processed and modelled to show a highly encouraging chargeability and resistivity response coincident with the previously identified anomalous soil areas.
Inversion modelling of the IP data has defined a west dipping 650m x 200m wide IP high chargeability anomaly (>9mV/V, up to 30mV/V) which overlies a strong IP high resistivity (>1000 Ohm.m) anomaly Figures 1, 2 &3).
The Induced polarisation technique is often used in porphyry exploration to detect the presence of disseminated sulphides over a large volume of mineralised rock such as a typical pyrite alteration halo associated with porphyry mineralisation. Strong high chargeability anomalies with spatially associated high resistivity anomalies at Ringaroo suggest the potential presence of Porphyry style Cu-Au mineralisation. The IP anomalies are supported by surface soil geochemical samples and correlate to high Au and Cu results within a magnetic high feature. Previous ground exploration by Sultan has also identified Ordovician volcanics in the project area containing polymict volcaniclastic conglomerates and volcanic breccias. Significant reddening, or hematite dusting, of feldspars has been noted from petrology of hand samples. This type of host rock alteration is common to both the Cadia and Northparkes porphyry Au-Cu deposits. The Ringaroo prospect geology has been mapped by the Geological Survey of NSW as the same Macquarie Arc volcanic rocks that host Alkane’s recent Boda

Note the very strong chargeability ‘bullseye’ beneath anomalous gold in soil response. The 650m wide IP chargeability anomaly ranges from >9mV/V up to 30mV/V. A 350m wide resistivity high anomaly to the north is also evident on the section
Future Work Program - Ringaroo
The IP results have enhanced the Ringaroo targets potential for host porphyry Au-Cu mineralisation. A strong magnetic feature overlain with anomalous Au and Cu soil response and coincident IP chargeability highs is a compelling recipe for porphyry occurrence. Field mapping has noted alteration styles reminiscent of that associated with porphyries and rock sampling of the magnetic feature a short distance to the North by Impact Minerals has uncovered high copper grades at surface (see ASX Announcements 14/01/2020 and 23/04/2020). Future work at Ringaroo will include:

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
Rock sampling programs
-
Rock samples are 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 are collected
Soil sampling programs
-
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 is 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.

| 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 | ||
