I talked to Eira Thomas at Stornoway and Roswitha at TWG. I did not get to talk to Hermann and I did not inquire as to what pipes were drilled or how much. As I guessed, their (TWG) core went in late and they are waiting on results. Madam Serious, Eira Thomas, at Stornoway-Navigator, waxed eloquent about peridotitic vs eclogitic chemistry at AV1, the Melville Island discovery. She is of the opinion that the original Diamet? chemistry was not significant of pyrope, but of eclogitic garnets. This is a shocker. But she also said that the chemistry was good for both eclogite and peridotite garnets.. i.e. pyrope.. I was getting hazy on this stuff as it was rushed.. She said that the key to Melville may be its eclogitic component. This may be more important than the pyrope found so far, and of course there is also the diamonds. I did not find the pyrope graph that exciting. I have seen better in more recent plays. The garnets were all above 3% calcium. They were also close to the so called g10/g9 line, albeit high in chrome. This is not really subcalcic pyrope. It is not terrible, but it is not subcalcic rigorously, by Sobolev's defiinition. However the diamonds are there. So an eclogitic pipe ortwo, like the Premier, is a possibility for that showing. The field may be something entirely different. You would not expect an eclogitic field but anything is possible. Seeing both peridotitic and eclogitic chemistry is rare. Seeing so-so pyrope and good eclogitic chemistry you would think is also rare. Usually kimberlites high in eclogitic garnets are pyrope- sparse. This includes Orangeites, Kimberlites, and Lamproites.
