Ann: Gifford Creek Niobium Drilling Update, page-32

I asked DT about the assays coming back and also how they dyke of niobium is known when they haven't drilled it yet.
His response:

Samples from both infill and extension have been fast tracked. But they are in separate batches. Infill samples will come first which we are expecting in the next week or two.

We do not know there is one, those are conceptual targets.

We, based off our drilling at C3, that there are multiple phases of intrusion that have a southwestern dip and generally dyke like shape in the fresh mineralisation.

We know that we have fresh Nb mineralisation in holes CBRC110 and CBRC111 (as well as others).

So, based on the information we have from drilling to date, we know that the intrusions (including the overall GCC which is kind of a “Mega Dyke” to use the words of Jon Hronsky, have a general dyke like shape and southwestern dip. And we know that Nb mineralisation occurs in at least two forms, being pyrochlore enriched carbonatite and siderite ilmenorutile veins with varied orientations. And that we have fresh pyrochlore mineralisation nearby in holes CBRC110 and 111.

We also know that oxide / residual / weathered mineralisation forms a blanket like geometry from the weathering of fresh mineralisation as the Nb (and REE and Ti and Sc etc) mineralisation is resistate and does not break down, it remains behind when the carbonate host rock is weathering away. Thus, if we have oxide mineralisation, then it must have come from somewhere nearby.

This is like using oxide gold mineralisation to help find and chase bedrock gold mineralisation.

Those fresh dykes in the diagrams are conceptual targets that we will drill with the next round of drilling. This will allow us to continue to assess the oxide mineralisation as well as test for the fresh rock source.

Moreso than REE deposits, Nb deposits are equally developed in oxide as in fresh. An exmaple fo this is Niobic which is a currently operating underground Nb mine, all in fresh rock, and the mines at Catalao are exploiting fresh material in addition to oxide. Hence the fresh dykes are compelling targets to be tested which we have not done in earnest to date.
