MOUNT BURGESS MINING N.L. Report for the Quarter ended 31 March 2022
Highlights of work conducted during the Quarter:
• Nxuu polymetallic Zn/Pb/Ag/V2O5/Ga/Ge Deposit. Samples from diamond core drilling conducted in Oct/Nov/Dec 2021, were submitted for assaying during the quarter. Results from seven drill holes received to date have been incorporated to update the Nxuu Deposit assay data base.
• Kihabe polymetallic Zn/Pb/Cu/Ag/V2O5/Ga/Ge Deposit. With the recent increase in the Gallium price a review was conducted on all Gallium assays received to date from the Kihabe Deposit. Only samples from drilling conducted in 2017, were assayed to include Gallium.
• Mineralogical test work conducted by University of Tasmania. Samples from the Kihabe Deposit were sent to the University of Tasmania to conduct mineralogical test work to confirm the host minerals for Gallium and Germanium
• A MOU for a potential power supply for the project was signed with Botala Energy Limited.
NXUU DEPOSIT ASSAY RESULTS
Assay results from seven Nxuu Deposit diamond core holes received during the quarter have been incorporated into the Nxuu Deposit assay data base.
The incorporation of assay results from these seven diamond core holes now enables data to be assembled for results from thirty diamond core holes. Details of the seven holes, announced to the market in April, are shown in bold in the various tables and in red on the attached drill hole map Figure 1. The combined 30 drill hole results show the following.
Weighted Average Grade
• 607.45m of Ga intersections give a weighted average grade of 10.8g/t, applying an 8g/t low cut (Table 2)
• 403.10m of Zn mineralisation give a weighted average grade of 2.0%, applying a 1% low cut (Table 3)
• 230.95m of Pb mineralisation give a weighted average grade of 1.5%, applying a 1% low cut (Table 4)
• 124.10m of Ag mineralisation give a weighted average grade of 22.1g/t, applying a 10g/t low cut (Table 5)
• 275.83m of V2O5 mineralisation give a weighted average grade of 1,224ppm (1.2kg/t) applying a 250g/t low cut (Table 6)
• 135.28m of Ge mineralisation give a weighted average grade of 5.6g/t, applying a 4g/t low cut (Table 7)
The assay results from the seven drill holes support and or improve the tenor and extent of the assay results of previous resource drilling campaigns.
Average Depth to Base of Mineralisation
Mineralisation in the Nxuu Deposit occurs in a quartz wacke situated within a shallow barren dolostone basin.
The 30 drill holes overall contain 195.06m of Kalahari sand cover and 1,024,24m of mineralised quartz wacke, totaling 1,219.30m (Table 1).
On average, the depth to base of mineralisation of the 30 drill holes is only 40.64m.
Average Percentage of Lengths of Mineralisation
The 26 holes assayed for Gallium contain 607.45m of mineralisation in 1,036.20m, to the base of mineralisation (Table 1).
On average 58.62% of the 26 hole lengths contain Gallium mineralisation.
The 30 holes assayed for Zn/Pb/Ag/V2O5/Ge contain 403.10m of Zn mineralisation (Table 1) + 210.16m of Pb/Ag/V2O5/Ge mineralisation which extend beyond the Zn mineralisation. This totals 613.26m of mineralisation in 1,219.30m to the base of mineralisation.
On average 50.30% of the 30 hole lengths contain Zn/Pb/Ag/V2O5/Ge mineralisation.
Assay results from a further ten diamond core holes are pending
