MARYMIA (80%)

 

The Marymia Project is located approximately 900 kilometres north of Perth within the Archean Marymia Inlier. The project is situated 40 kilometres east of the Plutonic Gold Mine, 20 kilometres southeast of the Marymia gold camp, and 55 kilometres northeast of Sandfire Resources NL’s DeGrussa copper mine. Exploration by Norwest at the Marymia Project employed reverse circulation (RC) drilling to test two high-priority targets being the Jenkins Volcanogenic Massive Sulphide (VMS) soil anomaly and the Dixon North Magnetic Anomaly (gold).

In March 2019, a first pass RC drilling programme at Marymia’s Jenkins prospect intersected relatively wide zones of near surface anomalous zinc and lead mineralisation trending along a 1.2-kilometre strike. The Company has planned an extensive infill aircore drilling programme to test the area for economic zinc & lead mineralisation. The drilling is scheduled to commence during mid-2020.

Jenkins Prospect RC Drilling

The Jenkins VMS RC drilling returned several significant intersections with anomalous +0.1% lead (Pb) and zinc (Zn) results. The drilling intersected the Juderina and Johnsons shale sequence which are intruded by an ultramafic.  The ultramafic has a chlorite schist upper component, a Talc Chlorite phase and a Peridotite phase.

The drilling tested the hangingwall and footwall Juderina and Johnsons shale positions, as well as the ultramafic unit with the sequence appearing to dip to the north at around 60 degrees.

The mineralisation zone is in the hangingwall position of the Juderina and Johnsons shale (MMRC19007, MMRC19005 and Australian Mines Ltd hole MMRC003).  This mineralisation is primarily Zinc rich with intersections including 3m @ 0.55% Zn in MMRC1905 and 9m @ 0.28% Zn in MMRC19007.  Below the zinc mineralisation there appears to be a zone of Pb mineralisation in the ultramafic which includes intersections of 25m @ 0.34% Pb in MMRC19009 (inc. 2m @ 1.2% P).  continuity of the anomalous Zn/Pb mineralisation extends over 1km along strike. Follow-up aircore drilling of the Zn-Pb anomaly is being planned to test for economic level of mineralisation along strike and at depth.
