The coastal area has reported historical gold production from four prospects: Tozers, Boiler, Nickol South and Lydia. Now on granted mining leases, we are advancing these discoveries.

Reported historical gold production at Nickol River comes from four main areas: Tozer’s, Boiler, Nickol South and Lydia. These prospects are located 14 km east of Karratha and just north of the Northwest Coastal Highway. Artemis has entered into a partnership with the D & K Corps Investments Pty Ltd for access to some of their mining leases.

 

Nickol River mining

The Company has identified significant areas at Nickol River that are highly weathered and free-dig from surface to depths of between 2 - 6 m that would potentially be amenable to bulk scale mining and processing using a modern gravity plant for gold recoveries.

Also, as previously reported on 25 January 2017, previous trial mining operations at Nickol River reported by Sir Samuel Mines NL listing Prospectus, noted that in 1984 a 10 tonne per hour plant tested 600 t of surface material yielding a recovered grade of 0.33 g/t Au and in 1985 a bigger 40 t/hr pilot plant processed 42,500 t of surface material yielding a recovered grade of 0.15 g/t Au.

There are currently no Mineral Resources reported in accordance with the JORC Code at Nickol River as the previous work outlined in the 1980s in the Sir Samuel Mines NL Prospectus was published prior to the existence of the JORC Code.

Nickol River exploration

Prior to Artemis historic work on the Nickol River tenements included 58 RC Drill holes, mapping and soil sampling.  In 2012 Artemis carried out auger soil sampling in the western portion of P47/1518 (now M47/1527) as well as a limited rock chip sampling program to confirm the earlier results. The auger sampling identified broad gold anomalies, with a maximum assay result of 6.9 g/ t Au. The rock chip sampling also returned anomalous Au with results of up to 14.8 g/t Au from the Samantha Lode. The work completed by Artemis confirmed the tenor of gold mineralisation as identified in the historic exploration activities.

The gold geochemistry from the 2018 regional sampling program discussed earlier in this section is strong over the Nickol River alluvial area, Figure 33. This is in part due to the extensive disturbance by mining over the area, however the geochemistry generally suggests the known shear zones hosting primary mineralisation as at the Samantha, Tozers and Boiler zones may be replicated elsewhere.

Artemis has taken bulk samples from a series of trenches to better define gold mineralisation and guide further drill hole planning

Historic drilling at Nickol River identified intersections of up to 4m @ 9.70 g/t Au (NR16), and 3m @ 34.5 g/t Au (MRC13). Artemis has completed some bulk sampling under Programmes of Work for a series of trenches to better define gold mineralisation and guide drillhole planning.
