Announcement PDF Sultan Resources Ltd CORPORATE DETAILS ASX Code: SLZ DIRECTORS JEREMY KING CHAIRMAN STEVEN GROVES NON-EXECUTIVE DIRECTOR ASX ANNOUNCEMENT 16th August 2023 DAVID LEES NON-EXECUTIVE DIRECTOR www.sultanresources.com.au info@sultanresources.com.au HELICOPTER EM SURVEY TO ASSESS GEOPHYSICAL ANOMALY COMMENCES ON E70/5082 o Sultan have contracted New Resolution Geophysics (NRG) to undertake a helicopter-borne Electromagnetic (EM) survey system to better assess a conductivity anomaly identified from existing broad-spaced EM data on E70/5082, SW of Kulin in WA. o The heli-borne EM survey is being funded by Rio Tinto Exploration (RTX) pursuant to the recent option and farm-in arrangement between Sultan and RTX whereby RTX has rights to earn up to 80% of E70/5082 through $2M of exploration expenditure. o The new heli-borne EM survey will utilise NRG’s advanced “Xcite” system and be conducted at 100m line spacing, for a total of approximately 80 line km, commencing today. ______________________________________________________________________ Sultan Resources Ltd (ASX:SLZ or the Company) is pleased to advise that an initial phase of exploration has commenced on E70/5082, where a recent option and farm-in agreement allows Rio Tinto Exploration Pty Limited (RTX) to undertake preliminary exploration during an initial option period and then elect to earn an 80% interest in E70/5082 by way of $2m of exploration spend within 5 years (refer SLZ announcement 21st June 2023). E70/5082 forms part of the Company’s broader Lake Grace exploration project. The Company has contracted NRG to fly a detailed (100m line-spaced) helicopter-borne time-domain electromagnetic (HTDEM) survey totalling around 80 line km over an area approximately 4km SW of the wheatbelt town of Kulin (refer Figure 3), with acquisition of data commencing and expected to be completed today. The target was initially identified by RTX geoscientists after review of existing wide-spaced (20km) airborne EM data. ASX ANNOUNCEMENT – 16 TH AUGUST 2023 From modelling of the existing data (refer JORC Table 1 at the end of this release), RTX identified a strong untested late time conductivity anomaly (refer Figure 1 below) in the northern part of E70/5082, coincident with a circular magnetic and radiometric anomaly (refer Figure 2 below), suggesting potential for magmatic nickel sulfide mineralisation. The new heli-borne EM survey is aimed at confirming the nature and extent of the conductivity anomaly before considering the merits and nature of any on-ground exploration to further assess and test the anomaly.

About Sultan Resources Sultan Resources is an Australian exploration company with a portfolio of quality assets in emerging discovery terranes. Sultan’s tenement portfolio includes recently acquired lithium-prospective claims in NW Ontario in Canada; a tenement package in the southern terrane region of the Yilgarn Craton in the eastern wheatbelt of Western Australia with priority nickel-cobalt and gold targets, where Rio Tinto have recently formalised a farm-in JV on a central tenement; and tenements located in the highly prospective east Lachlan Fold Belt of Central NSW considered prospective for copper and gold. Sultan’s board and management is committed to the responsible discovery of metals via modern exploration techniques, and to add value to these projects for the benefit of the company and its shareholders. page 4 ASX ANNOUNCEMENT – 16 TH AUGUST 2023 JORC CODE, 2012 EDITION – TABLE 1 Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.) Criteria Commentary Sampling techniques • • The data represents the first phase of the AusAEM2020 (WA) survey flown with a with a rotary aircraft contracted to Geoscience Australia, using the SkyTEM® airborne electromagnetic system. The survey was flown at a 20-kilometre nominal line spacing over the most southwestern part and down to the southern coast of Western Australia. The accompanying data package, titled “AusAEM-WA, SouthwestAlbany Airborne Electromagnetic Survey Blocks:: SkyTEM® airborne electromagnetic data and GALEI inversion conductivity estimates”, was released on 4 November 2021 by Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA).
