Aircore drilling of interpreted ultramafic occurrences in the Lake Grace area in the search for Julimar-style Ni-sulphide targets commenced in Mid-December
-
Ultramafic lithology confirmed in early holes
-
Approximately 2km strike of ultramafic lithology confirmed at first target zone
-
The targets lie within part of interpreted mobile zone that hosts the recent Julimar NiCu-PGE discovery
-
A program of up to 29 holes targeting areas of known and interpreted ultramafic occurrences is underway
-
Historic exploration at Lake Grace has shown ultramafic rocks with evidence of nickel and cobalt bearing sulfides in drilling
-
Strong geophysical evidence for >25km of cumulative strike length of ultramafic rocks across Sultan’s Lake Grace portfolio
-
Lake Grace portfolio surrounded by major mining and exploration companies:
-

-
Gold Road Resources to east
Sultan Resources Limited (ASX: SLZ) ( Sultan or Company ) is pleased to announce the commencement of the first phase of reconnaissance exploration aircore drilling for nickel-prospective ultramafic rocks at identified magnetic anomalies within the Lake Grace prospect. The project is located in the Wheatbelt area between Lake Grace and Kulin in WA where the company has been exploring since listing in 2018.
The Ni-prospectivity of Sultan’s Lake Grace tenement portfolio has long been recognised by the company (see ASX Announcement 20/07/2020, 20/11/2020) and has been verified by the discovery of Chalice Gold Mines’ Julimar Ni-Cu-PGE deposit 215km to the northwest in the same belt of rocks (see Chalice ASX announcement of 23/03/2020). Sultan’s licences contain historically drilled ultramafic rocks with evidence of nickel and cobalt bearing sulfides[1] and detailed airborne magnetic surveying by the company (ASX Announcement 03/07/2020) has revealed several unexplored areas with geophysical characteristics indicative of ultramafic rocktypes. The aircore program is designed to confirm the presence of ultramafic rocks interpreted from the magnetics interpretation and help determine the prospectivity of the region for hosting Ni-sulphide deposits

All of Sultan’s tenure lies within an interpreted mobile zone prospective for Ni-Cu mineralisation as postulated by Impact Minerals Ltd (see Impact Minerals announcement dated 10/06/2020)
Aircore Drilling Progress
The aircore program commenced at the northern end of the project at Kulin (E70/5095, Figure 2) where previously identified ultramafic rocks have been noted in historic drilling and mapping by Sultan (see ASX Announcement 20/11/2020). The first four holes at this target have been completed and geological logging has confirmed the presence of ultramafic lithology in at least 3 holes. The aircore holes lie approximately 2km northwest of the historic diamond holes and confirm the strike extent of this first ultramafic target.
The rig will aim to traverse further ultramafic-prospective areas across E70/5095 prior to Christmas and return to finish the program further to the south on E70/5085 in January 2022 (Figures 2 & 3). Full geochemical analysis coupled with petrographic interpretation and possible QEMSCAN testing will be undertaken on bottom of hole samples.

The Project lies in the Lake Grace Domain of the Southwest Terrane. It is comprised of granulite facies granitic gneisses, gneissic remnants of greenstone belts, charnokitic granites and post-tectonic granites. The greenstone rock sequences are metamorphosed to high-grade upper amphibolite to granulite facies. Structurally- controlled gold mineralisation occurs broadly as multiple, well-defined stacked elongate to ellipsoidal lodes that vary in size from 1-10 m thick, 50-150 m wide (east-west) and 50-200 m long (north-south) that have undergone post- mineralisation deformation. The gneissic package dips between 35° to 40° to the southeast and strikes 040°. The host rocks form anopensynform thatplunges 30° toward120 |

| Relationship between mineralisation widths and intercept lengths |
·These relationships are particularly important in the reporting of Exploration Results. |
No mineralisation referred to in the document |
| ·If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
||
| ·If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
Any intersections included in the accompanying report are down hole lengths. The true widths of these intersections are not known. |
|
| Diagrams | ·Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |

| Balanced reporting | ·Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
The accompanying document is considered to represent a balanced report. The author has referenced numerous ASX releases by neighbouring exploration companies where balanced reporting is considered to have been undertaken. |
| Other substantive exploration data |
·Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
The author has referenced publicly available historic reports where balanced reporting is considered to have been undertaken. Otherwise the balance of the information is not considered material. |
