In July 2019 Norwest purchased of the historical Bulgera Gold Project situated within the Plutonic Well greenstone belt and 10 kilometres from Company’s Marymia project tenements. Mining at Bulgera ceased in 2004 after a short period of exploiting near-surface gold ore for processing at the nearby Plutonic gold plant. Bulgera’s extensive historic exploration, development and mining database shows multiple gold lodes extending below the shallow open cut pits and along the 5-kilometre strike of the sheared greenstone package1. Remodelling of the historical Bulgera drilling data is aimed at identifying and reporting the remnant gold resources that comply with JORC 2012 standards. Reverse circulation (RC) drilling will be undertaken to extend the known near-pit and near-surface gold mineralisation at Bulgera. Aircore drilling will focus on zones away from the mined area where thick transport cover has masked the geology and mineralisation which is believed similar to the nearby Vango Mining prospects where numerous gold drilling intercepts are currently being reported to the ASX.
Norwest is also targeting a 4 x 8-kilometre coincident magnetic-gravity anomaly having geological features analogous to world class iron-oxide-copper-gold (IOCG) deposits such as those hosting Olympic Dam and Ernest Henry2. Norwest Minerals is the first company allowed access to drill into the large North Dovers iron-oxide-copper-gold (IOGC) target following its identification by BHP 20 years ago. Results from the three diamond holes drilled in May 2019 have been very encouraging with the Company commencing a large reverse circulation (RC) follow-up drill programme to more fully test the 4 x 8 km anomaly.
A brief description of Norwest’s other WA resource projects follow.
The Arunta West project - prospective for iron oxide copper gold (IOCG). A 4km by 8km coincident gravity-magnetic anomaly at the North Dovers prospect is the target of several deep diamond drill holes. Norwest will be the first explorer to drill at North Dovers with the work scheduled to commence May 2019.
Bali: The Company undertook a project-wide airborne electromagnetic geophysical survey designed to highlight conductors representing potential primary copper mineralisation that may be located within the project area3. Processing of the data to date, failed to reveal strong, discrete EM anomalies that present as walk-up drill targets. Further ground survey work and geological interpretation is being considered.
Bulgera: On 9 July 2019 Norwest Minerals announced the 100% acquisition of the Bulgera Gold Project (“Bulgera”) located 200 kilometres north of Meekatharra with an existing haul road to the Plutonic Gold operation4. Bulgera's historic exploration, development and mining database shows multiple gold lodes extending below the shallow open cut pits and along the 5-kilometre strike of the sheared greenstone package5.
Marriotts: remodel the existing Inferred Resource of 662,000 tonnes at 1.3% Nickel for 8,700 tonnes of contained nickel with the aim of converting part of the resource from Inferred to Indicated classification. Also, conduct a small study into sale or toll treating options of the resource.
Marymia: 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 early next calendar year.
The Ninghan Project - consisting of four tenements, was acquired together with Norwest’s 100% purchase of the Warriedar project tenements. The Ninghan tenements are prospective for gold and base metals and are located approximately 40 kms southeast of the Warriedar package and 20 kms west of the former Gold Rush settlement of Paynes Find.
Warriedar/ Ninghan: RC drilling, surface sampling and ground magnetics were completed at Norwest’s Warriedar Project. Gold mineralisation was intersected at the Mount Laws prospect from near-surface to over 150 metres deep along a strike of over 200 metres. At the nearby Ninghan tenements, aircore drilling and soil sampling highlighted several gold targets to be followed up with RC drilling.
