Mt. Roe Project

The Mt. Roe Project is located approximately 30km south of Karratha in the Pilbara region of West Australia. The Pilbara region is known for its iron ore deposits and substantial associated infrastructure. Since 2016 the Pilbara has also been known as an emerging area for significant gold potential specifically in paleoplacer-style or Witswatersrand-style conglomerate hosted gold deposits.

Mt. Roe Project

The Project encompasses two sets of tenements, the Mt.Roe and the Prinsep, covering 1,232ha of land immediately adjacent to Novo Resources Karratha Gold project and Artemis Resources Silica Hills property.

Exploration

On the MT.ROE tenements, conglomerate has been identified below an inferred equivalent of the Mount Roe basalt. This unconformity has been traced by way of mapping and trenching for approximately five kilometers to the south-southwest along the base of the Sholl Ridge. Gold nuggets found on the property are a mixture of flattened ‘melon-seed’ nuggets characteristic of conglomerate hosted gold while others are more coarse specimen type nuggets. Gold nuggets found in certain areas of the property exhibit the same characteristics as recent nugget discoveries in conglomerate host rocks by Novo Resources, Artemis Resources, De Grey Mining and Kairos Minerals Ltd.

Exploration activities to focus on areas of the unconformity hosting gold mineralisation included: mapping which indicted numerous cross faults, both ancient and more recent; trenching to identify areas of sedimentary units on the unconformity; and stream sampling to determine areas of the unconformity potentially shedding gold.

Given the proximity of the Artemis Resource coarse gold vein style mineralisation at Silica Hills, roughly 600m southeast, NxGold undertook a more traditional exploration approach which included detailed unmanned aerial vehicle (“UAV”) magnetics surveying, prospecting and soil sampling. This work was initially restricted to select areas of granted tenements but now the remaining tenements have been granted, a similar systematic work approach will be undertaken on the recently granted tenements to generate targets at which time all target areas will be prioritised for more advanced activities such as drilling.

Currently nine target areas have been identified as listed below:

Bulldog: historical nugget location, strong stream anomaly, underlain by large circular magnetic high feature; possibly part of the unconformity related conglomerate hosted gold, proximal to breccia dyke.

Cat: weak stream anomaly, part of unconformity related conglomerate hosted gold, requires field follow up.

Conglomerate: location of outcropping conglomerate and sediments, part of unconformity related conglomerate hosted gold, basin forming shear structure structures, proximal to historical nugget collecting areas and dryblowing area.

Crow: strong stream anomaly; local sub-cropping Cu-Au vein.

Eagle: strong stream anomaly, historical specimen nuggets, trenching exposed gold bearing vein, moderate to strong soil anomaly, underlain by large circular magnetic high feature; possible relation to unconformity related conglomerate hosted gold.

Hawk: strong stream anomaly, strong soil anomalies, below historical 80oz nugget patch, strong soil anomaly.

Kangaroo: moderate stream anomaly; on edge of large circular magnetic high feature, location of historical nugget collecting, part of unconformity related conglomerate hosted gold.

Sun: strong stream sample anomaly, location of NW-SE trending 50m pinch and swell quartz vein.

Swan: moderate stream anomaly, historical dryblower area, weakly auriferous veins exposed during trenching, cross structure anomalous in copper.

The PRINSEP tenements have only received an initial pass of stream samples and wide spaced soil lines with limited mapping and prospecting. No anomalous signatures were picked up with the first pass stream samples. Wide spaced soil grid lines covered areas of historic nugget searches.
