 6 m lifts, leaving 5 m x 5 m post-pillars in a regular grid to support 
 subsequent operations. This method minimizes internal waste mining and suits the orebody     
 geometry while allowing high productivity and efficient backfill placement.                  |

These mining methods
were selected and designed following geotechnical assessments and are tailored to ensure high recovery and ground stability across varying
bed dips and thicknesses.

Previous DAF designs
made for the FW zones (January 2018) used internal stope ramps, which were developed on apparent dip within each bed. However, this design
test work made clear various disadvantages:

| ● | High dilution with the internal 
 stope ramp itself.              |

| 95 |

| ● | High losses with pillar wall next       
 to stope ramp.                          |
| ● | Very difficult drive intersections      
 with stope ramp, in areas of lower dip. |

In the stepped drift-and-fill
method, single drift-and-fill headings will be extended along strike, close to horizontal, with inclined shanty backs so as to reduce
dilution at the hanging wall contact. DAF headings will be developed with width from 3 m to 6 m. DAF panel lifts will be stepped up in
approximately 2 m vertical intervals, which corresponds with the average 22° degree dip of the F2, F3 and Main beds.

The method will use
external stope ramps, located on the footwall side of the ore zones, approximately 20 m below the bottom bed. Due to the low orebody
dip, this means at any particular elevation, the ramp will be approximately 70 m horizontally to the south of the F3 bed. At the bottom
level elevation, a stope crosscut will be developed from the ramp, going northwards until it intersects the first ore horizon (generally
the F3). For the F2/F3 area, the stope crosscut can be approximately horizontal, and will then normally be extended on to also intersect
the F2 bed. This will often allow four production faces, which can be developed along the F2 and F3 beds at that elevation. The stope
drives will need to be of a variable width, from 3m to 6m, so as to have the floor of the next (higher) stope drive located approximately
2 m higher.

In most cases, with
