In March 2018, the Boorara TOTAL GOLD RESOURCE is now up 118% to 507,000 OUNCES.
MRP Resources March 2018 estimate - total Mineral Resource at the Boorara Gold Project of 16.45 Million Tonnes @ 0.96 g/t for 507,000 oz of gold is based on a 0.5 g/t gold cut-off grade (previously used 0.4 g/t) with a maximum top cut grade applied of 40 g/t.
The MRE has been estimated at a 0.5 g/t lower cutoff grade for the Boorara Gold deposit as follows:

The Other Material Information required by ASX Listing 5.8 and the JORC Code, 2012 Edition Table disclosures are included in the announcement dated 6 March 2018.
Nimbus project near Kalgoorlie mineral resource of 12.1 million tonnes at 52 g/t silver, 0.2 g/t gold and 0.9% zinc containing 20.2 million oz of silver, 78,000 oz of gold and 104,000 tonnes of zinc. (See table below and ASX announcement 30 April 2015.) This represents a 58% increase in silver, a 60% increase in zinc and a 66% increase in gold compared with the previous 2013 Mineral Resource Estimate Statement.
The Nimbus resources are in addition to the 232,000 oz of gold located at Boorara deposit 1 km southwest of Nimbus.
In May 2016, a new high grade silver zinc resource was estimated from within the global Nimbus resource of 12.1 million tonnes at 52 g/t silver, 0.9% zinc, 0.2 g/t gold containing 20.2 million oz of silver, 78,000 oz of gold and 104,000 tonnes of zinc.
The high grade underground silver zinc resource for the Nimbus project of 255,898 tonnes @ 773 g/t Ag and 13% Zn has been estimated using a higher modelling cut-off grade of 500 g/t Ag and a top cut grade of 2800 g/t Ag was applied.
The high grade resource inventory includes lodes 3, 4, 5 & 7 from the high grade silver zinc resource which total 132,075 tonnes @ 968 g/t Ag & 19.36 % Zn (bottom cut-off grade 500 g/t Ag & top cut grade 2800 g/t Ag).
The recently increased geological understanding of Nimbus deposit provides MRP with a high level of confidence in the new high grade silver zinc resource, however further work is required to bring the resource up to a level required for future Ore Reserve estimations to be completed.
