ASX ANNOUNCEMENT
29th October 2019
EXCEPTIONAL GRAVITY RESULTS HIGHLIGHT GOLD POTENTIAL AT LAKE GRACE
Highlights
- Detailed ground gravity survey covering 20km of gold mineralised terrain completed
- Results show numerous prominent gravity targets associated with historic and recent gold mineralisation in drilling
- Very strong, 2km long gravity high associated with Challenger Gold Prospect – down dip of recent gold intersections in drilling:
- o shows strong similarities to the gravity response that marks the Tampia Gold Deposit
- o Larger than the Tampia gravity anomaly
- Gravity survey indicates a +17km trend of dense mafic lithology extends NW from Challenger and remains untested by deep drilling
The Board of Sultan Resources Ltd (Sultan or the Company) is pleased to advise that the detailed ground gravity survey at the Company's Lake Grace Project (see ASX announcement 23/09/2019) has been completed. Designed to cover the Challenger Prospect and extend northwest along the gold-hosting regional structural trend, the survey has successfully provided detailed geological information on the dense, mafic gold-hosting rock types and highlighted numerous prominent gravity anomalies associated with areas of historic and recently discovered gold mineralization.
Managing Director, Steve Groves commented: "The results of the gravity survey are exceptional. The strong gravity response at Challenger lies immediately adjacent to our recent successful RC drilling, where we have drilled the near-surface area of what looks like a very large gold mineralising system that dips tantalizingly towards a huge, arcuate gravity anomaly that has very similar properties to that which marks the Tampia Gold Deposit. It remains untested by drilling. Furthermore, the gravity survey has identified a number of additional targets, all of which are coincident with historic gold anomalism. This paves the way for some exciting exploration programs for Sultan in the near future."

Survey Details
The survey was designed to provide high resolution gravity data across the recently drilled Challenger Gold Prospect and extend north-west to cover historically identified1 gold anomalies associated with mafic rock types. A total of 2156 ground gravity readings were acquired by Atlas Geophysics between 23/9/19 and 8/10/19. Readings were taken at varying spacings along east-west lines mostly positioned 200m apart. Closer spaced readings were taken around the Challenger prospect on a 100m x 100m grid. All data was forwarded to Core Geophysics where readings were corrected to produce a spherical cap bouguer anomaly (SCBA) with all processing and imaging using a value of 2.67 gm/cc in the bouguer correction (Figure 2). Core Geophysics then performed a detailed analysis of the data to identify targets prospective for gold mineralization.
Survey Results
The survey has revealed at least four prospective targets (Figure 2), the most prominent of which exists at the Challenger Gold Prospect where recent drilling by Sultan has discovered thick zones of significant gold mineralization over a wide area2 . All four targets are all associated with recent and/or historic gold anomalism.

Figure 2. Proposed exploration targets for the Challenger gravity survey with recent and historic significant gold results
Target 1 – Challenger Gold Prospect
A large gravity high has been mapped at the Challenger prospect and is likely to represent a mafic gneiss/granulite given this was recorded in EOH geology for several historic air-core holes that traverse the anomaly. The 2km long, slightly arcuate high encloses the recent drilling by Sultan2 and remains untested by deeper drilling. All historic Aircore/RAB drilling was either too shallow or stopped in highly weathered bedrock to provide an effective test of the gravity high. The two historic diamond holes drilled by North Ltd1 collared on the southern edge of the high but drilled at an angle away from it. Both holes intersected significant gold mineralisation that is interpreted to be dipping towards the gravity anomaly. Sultan's recent RC drilling also intersected significant gold mineralisation that is interpreted to be dipping down towards the gravity high. Three-dimensional inversion modelling of the gravity high shows it to be separated from magnetic units and strongly reflects the prospective petrophysical association observed at the nearby Tampia deposit3 . Another feature of both the gravity and magnetic data is that the sequence appears to be folded, with a plunging synform geometry evident. Fold axes in similar geometry host some of the high-grade gold at Tampia3 .

Figure 3. Comparison of the 2km long Challenger gravity anomaly to the Tampia gravity response at the same scale. Note that the accurate shape at Challenger could indicate a folded sequence and the proximity to previous deeper drilling at Challenger (blue dots) suggesting that the most prospective area af the gold-hosting stratigraphy remains untested.
Target 2 – Apollo Prospect
This target is located about 6km northwest of Challenger, along the interpreted line of mafic gneisses and is characterised by a discrete gravity high similar in amplitude to that of the Challenger prospect. The target is adjacent to North's historic Apollo prospect1 , where numerous shallow RAB holes returned highly anomalous gold results (Figure 2) The target could represent an untested zone of non-magnetic mafic gneiss and 3D inversion of the gravity data indicates that rocks below the gravity high reach a peak density of around 3 gm/cc at a depth exceeding -100m RL. Although the residual gravity anomaly indicates this is an isolated target, it is possible that this once formed a part of a larger fold closure with Challenger at the distal south-east end. Core Geophysics recommend that the target is prospective for Challenger style, non-magnetic mafic gneisses and/or a possible gold target of an unknown association.
Target 3 – Columbia Prospect
This target is located about 16km northwest of Challenger, along the interpreted line of mafic gneisses and is characterised by a broad gravity high coincident with a structurally disrupted magnetic unit. The target is adjacent to North's historic Columbia prospect1 , where shallow RAB drilling returned highly anomalous gold results including 5m @ 0.18g/t Au and 4m @ 0.11g/t Au (Figure 2). Core Geophysics note that the target represents an enigmatic confluence of several parallel north-south faults crossing a northwest trending magnetic unit. Of note is the disruption (shearing?) of magnetic units in conjunction with the change in density and is an unusual combination of structural disruption, increased density and magnetic susceptibility with the possibility of an intrusive rock mass at depth. The complex geophysical and structural signature, coupled with very significant historic gold results, renders Target 3 as an alluring regional exploration target for Sultan.
Target 4
This target is proposed due to geological and geophysical similarities with the Griffin's Find deposit. Although not specifically a gravity target, the qualitative similarity in magnetic stratigraphy makes this a compelling, but still speculative, exploration target. The geophysics show that the region of Target 4 is characterised by a broad, low-density rock mass which is consistent with the presence of a granitic intrusive. However, a visual comparison of the broader magnetic stratigraphy between Griffin's Find and here suggests that this package was once a likely repeat of the stratigraphy at Griffin's Find. Historic soil sampling results have returned anomalous gold values in the 6 – 10ppb Au range over the target4 . Although somewhat speculative, Target 4 should be considered as a possible correlative to the Griffin's Find deposit.

Figure 4. Target 4 - the residual gravity SCBA (left) and a TMI FVD (right) is overlain by SCBA residual contours. Exploration prospectivity should increase to the NW, away from the dominant granitic assimilation in the SE
Next Steps
Sultan is continuing to review the gravity results in conjunction with their recent drilling to design follow up exploration programs. The focus will be on the Challenger Prospect, where significant gold mineralization has already been discovered.

Thisgave flexibility to where field duplicates wereintroduced into the geochemical sampling streamto the lab and allowed for compositing at any depthor interval.●On a regular basis both sample and duplicate wereweighed with a simple hook based hand held scaleto check for representivity of both the metresampled and the duplicate.
