 215 m, different stope ramps have been designed to provide stope
access crosscuts into the central area of the stoping zone. These stope access crosscuts have often been designed with a downward gradient,
to a maximum of 13%. This will allow repetitive roof slashing of the stope ramps, so as to provide more stope access on progressive 2m
lifts. Much better recoveries are attainable by using DAF in the Main East zone. The advantages of this DAF mining method include:

| ● | High mining recoveries (minimal                              
 loss in ore pillars).                                        |
| ● | High productivities, as multiple                             
 primary panels can be accessed simultaneously.               |
| ● | Flexibility, with changes possible                           
 in panels due to variations in orebody geometry or faulting. |

In some very few
localized areas, the bed thickness can be more than 6 m, particularly in the Main East zone, and occasionally up to 8 m. In these parts
the first lower part of these panels can be mined out with a 3 m height and then backfilled. Short stope ramps will then be created longitudinally,
and upper panels will then be mined out with inclined roofs at top orebody contact.

| II) | Post-Pillar Cut-and-Fill |

This method has been
designed in those areas which generally have a vertical thickness greater than 5 m, which is the majority of the HW zone. Broadly, these
zones will be mined from the bottom-up in 6 m vertical lifts. Each lift will be mined out according to a regular mine-wide grid of 6
m wide stoping panels, leaving non-recoverable 5 m x 5 m post-pillars. The panels on the bottom-most lift of each stope block will require
a higher cement backfill, so as to provide a stable roof when stopes in the future are mined up from below.

Although the HW zone
is well-mineralized, there are erratic patches on internal waste. Based on this criteria, and previous studies involving the application
of a DAF method, it was decided to apply a PP-CAF method, with relatively large (6 m x 6 m) stope headings, around a regular pattern
of 5 m x 5 m non-recoverable post-pillars. This PP-CAF method offers the following advantages:

| ● | Minimal mining of internal waste.                               |
| ● | High productivity
