We are delighted to report very positive results from the first 11 of 27 holes drilled at Area D following the wet season. We have extended the thick oxide mineralisation by over 100m in multiple directions from the original discovery mineralisation with these step outs with more results pending. Deeper drilling has also intersected wide zones of mineralisation, with numerous mineralised structural zones pointing to likely controls on mineralisation. Results from the remaining program will assist to fully understand the controls of mineralisation. Whilst this discovery is still at an early stage, extensions to the thick oxide zones are very exciting. Results from an additional 16 holes from Area D are pending, as well as extensional drilling at Area A, which is ongoing. We are looking forward to releasing more results of this extensive program as they become available.commented Mike Brown, Managing Director and CEO of Chesser Resources.

The Company is pleased to report drill assay results from 3 diamond holes (DD) and 8 reverse circulation (RC) holes (totalling 573m and 1,094m respectively). All holes are from Area D, where the company reported a high-grade discovery earlier in the year (see ASX announcement dated July 28, 2020).

 

AREA D

 

These are the first results reported from the fully funded planned program of 5,000m DD drilling and 15,000m of RC drilling that the Company is currently undertaking at Diamba Sud. The initial 3 DD holes and 8 RC holes reported in this release are the first results from 7 DD holes and 20 RC holes the company has drilled at Area D since commencing the drill program.

 

The RC drilling results have significantly extended the thick oxide zones intersected by previously reported holes DRS153-157 (the “Discovery Traverse”)[ii]. All the RC holes intersected significant wide gold mineralisation within saprolitic material. The mineralisation was mainly oxidised, in the form of limonite after pyrite and/or staining, with minor fine-grained pyrite zones. Further drilling is needed to confirm if the oxidised material has a horizontal lithological control additional to a structural control. Bedding from DD holes suggests the sediments are dipping gently to the northwest, striking to the northeast.

 

RC Holes DSR173, DSR174 and DSR175 were drilled on an east-west traverse to the north east of Area D on the 1429525 Line. All three holes hit significant oxidised mineralisation in saprolitic sediments and hole DSR173 intersected a mineralised zone in fresh rock from 103m downhole depth. DSR175 has increased the oxide trend to the northeast at least 50m and remains open. Holes DSR173 and DSR174 have delineated what may be a northwest trending oxide zone at least 100min strike length, which is open to the northwest with further results pending.

RC holes DSR176, DSR177, DSR178 and DSR179 were drilled on an east-west section approximately 100m to the northwest of the discovery traverse (Figure 2). All four holes intersected thick oxidised mineralisation and significant wide zones of pyrite mineralisation in fresh rock. The holes are proximal to previously reported DSR103, which intersected 53m at 2.61 g/t gold.[iv] Further drilling is needed to confirm the relationship between these zones of mineralisation and a likely northwest trending mineralised structure.

DSR172 was drilled under the central area of the Discovery Traverse and intersected thick oxide mineralisation in saprolitic sediments: 37m at 1.28m g/t gold from 24m. At 90m downhole depth it intersected a pyrite mineralised zone in fresh rock. Further drilling is needed to determine the controls on the mineralisation.

Sulphide mineralisation

 

Drilling points to multiple potential structural controls, including the hydrothermal breccias, as the principal mineralisation system below the oxide mineralisation, which is very encouraging for further exploration work. Multiple intersections of pyrite mineralisation in DSR179, DSR178, and DSR176 suggest the mineralisation system may be extensive.

 

The initial 3 DD holes were drilled to test the depth extent of the high-grade oxidised and fresh rock mineralisation intersected in the Discovery Traverse, and to investigate the nature of a major NE trending structure. The holes encountered saprolitic sediments (fine grained sandstones and carbonates) transitioning into fresh limestones. Mineralisation was encountered in varying zones of extensive hydrothermal breccias with silica and carbonate matrix. Fine grained pyrite in stringers and matrix infill was observed in the breccia zones, with silicification and minor to moderate iron carbonate alteration.

 

Hole DSDD014 intersected a mineralised breccia in fresh rock that aligns with the northeast trending structure, that holes DSR155 and DSR156 intersected in oxidised material (Figure 3).[v] Further results and drilling are needed to confirm this interpretation.

 

Figure 3: 1429450N section showing drilling reported in this release intersecting a mineralised hydrothermal breccia , currently interpretated as trending NE, with a late NE regional fault indicated.[vi]

 

Hole DSDD016 was located at the southern end of the Discovery Traverse and intersected numerous mineralised and strongly silica/carbonate altered hydrothermal breccias in fresh rock. Results from DSDD017, drilled to the west and under DSDD016 are pending and should confirm the controls on mineralisation and orientation of the breccias.

NEXT STEPS

 

Drill Results Pending

 

The receipt of drill assay results is pending from 16 holes drilled at Area D (4 DD and 12 RC) as well as ongoing drilling from Area A. The company is looking to complete the expected 20,000m program in March 2021, with a steady flow of results expected until late April 2021. The Company is also planning to extend gradient array induced polarisation geophysics (GAIP) over the large parts of the northern Diamba Sud block (DS1) early in 2021. GAIP has been proved to be effective for identifying structures and certain lithological units (such as granodiorites). The Company is well funded to complete all these activities following a ~$6million private placement in July of this year.
