Bryah Resources Ltd (ASX:BYH) has received assays from 10 rock chip samples taken from Black Hill and Mudderwearie within the Bryah Basin Project in central Western Australia.
Grades reached as high as 52.12% manganese at Black Hill and 50.88% at the historical Mudderwearie manganese mine.
Further rock chip sample results due in the next two weeks.
Shares jumped 30% to 13 cents in early trade.
Drilling of the two prospects is to commence following the receipt of necessary approvals.
Early cash flow through shallow high-grade manganese
The company’s strategy now includes exploration for shallow high-grade manganese resources which may be exploited to provide an early cash flow.
The Bryah Basin is well known for hosting a number of historical manganese mining areas.
The majority of mining activities are known to have occurred during the period 1948 to 1967 with manganese production grades above 40% manganese reported.
Manganese mining is presently occurring on ground adjoining the company’s tenements at the Horseshoe Flats mine.

At the historical Mudderwearie mine there are two open excavated areas with some stockpiled material on site.
The Black Hill prospect is dominated by a manganese capped mesa.
Survey results due in late May
Both the northern and southern anomalous areas have been covered by the recently completed VTEM-Max electromagnetic (EM) geophysical survey.
This type of survey is a useful exploration tool for identifying buried manganese deposits.
Results are due in late May 2018.
