22° degree dip of the ore zones, one drive heading of 5 m width can be made at the design elevation, and the next lift
will then be 2 m higher. However, there is likely to be local variations in dip. If the orebody dip falls below 18°, then two or
more drive headings may be required at the same elevation, before stepping up to the next 2 m lift.

The stope drives
will be developed along strike in both the NW and SE directions, to a designed extent, generally approximately a maximum of 100 m, the
limit of forced duct ventilation. The total stoping length, with two faces on the same bed and same elevation, will generally be approximately
200 m.

The mined stope drives
will then be backfilled with paste fill. This will first require removal of any infrastructure from the mined stope drives and then installation
of backfilling piping. Backfilling barricades will then need to be built at the start of each stope drive. This filling operation will
need to be tight-filled as much as possible. The planned cement content for different stoping situations is summarized below.

| ● | Old stopes – 1%.          |
| ● | Active stopes – 3.5%.     |
| ● | Any undercut stopes – 7%. |

The emplaced backfill
will need a minimum of four-days’ curing time, before mining operations can continue.

The end of the stope
access crosscut with then need to be elevated, by a limited slashing of the back leaving enough waste to make a new ramp floor over a
small length, so as to provide a new stope access approximately 2 m higher than previously. The next stope drives can then be developed,
with one sidewall being ore, and the other sidewall being the backfill from the mining of the previous lift.

For the F2/F3 stoping
areas, this stoping cycle will be repeated for generally three lifts from the same stope access crosscut. For the next lift, a new stope
access crosscut will be developed from the stope ramp, approximately 35 m along-strike from the previous crosscut. In areas of the south
zone, when the Halo zone also occurs between the F2 and F3 zones, this can give up to six available faces on the same stope lift.

For the Main East
zone, which has a much more limited strike extent, of approximately
