The Marriotts nickel deposit is located approximately 70 km south of Leinster, and 80 km north of Leonora. Norwest holds a 100 percent interest in a single Mining Lease (M37/96), covering an area of approximately 0.16 square kilometres. The nickel deposit was remodelled in October 2019 to define a total resource of 743,000 tonnes at 1.07% Ni for 7,950 tonnes of contained nickel. A significant tonnage of the new resource reports to the higher confidence ‘Indicated Resources’ category as shown in the table below.

The new Marriotts model has a precise mineralisation wireframe which has increased the reliability of the interpretation resulting in the high amount of Indicated tonnage. The previous January 2018 model used a wireframe described an inaccurate in many areas which allowed some of the higher nickel drill grades to spread beyond reasonable limits during block grade interpolation. As a result of restricting the spread, the overall grade of the new Marriotts resource has dropped from 1.3% to 1.07%. (Note: the January 2018 Inferred resource totalled 662,000 tonnes at 1.3% nickel for 8.700 tonnes contained nickel metal)
A preliminary mining and economic study was completed on the new Marriotts resource.
The key findings are:
- At current nickel price Marriotts project produces a negative cashflow
- A nickel price of US$8.50 per pound is required to achieve a positive cashflow (no capital allocation)
- A nickel price of US$9.00 per pound produces cashflow of $6 million
