Ann: VRX Submits Arrowsmith North EPA Referral, page-63

One of the presenters at the Australian Energy and Minerals conference put
up a slide comparing VRX with other emerging silica sand producers in Australia.
With a sand purity quoted at 99.6% - 99.9% for VRX, its lowest grade (99.6%)
was higher that the best grade of all the others. And with a resource quoted
at 1,056 Mt, the sand resource is about 5 times larger than all the rest combined.
Clearly, VRX has the largest, and highest grade silica sand deposit amongst
the next generation of producers.
Numbers can be found on slide 10, "Presentation for Australian Energy and
Minerals Conference, 18/3/21, news ASX:MLM.

All IMHO, DYOR
