And what about this part:

Key Audit Matters

In addition to the matter described in the
Material Uncertainty related to Going Concern
section, we have determined the matters
described below to be the Key Audit Matters
to be communicated in our report:

The Key Audit Matters we identified are:

• Valuation of exploration and evaluation assets;
• Valuation of property, plant and equipment and mine development costs; and
• Valuation of ore inventory.

Key Audit Matters are those matters that, in our
professional judgment, were of most significance in our
audit of the Financial Report of the current period.

These matters were addressed in the context of our audit
of the Financial Report as a whole, and in forming our
opinion thereon, and we do not provide a separate opinion
on these matters.
