I basically had a standard lab WJ procedure, grind, sulphide float, gravity, regrind and tin flotation stage. The lode was 3.9%Sn, 2.2 % Cu and no Zn, diluted down to give the test work 1.5% Sn, 1% Cu. The cassiterite was coarse, the copper predominately chalcocite with minor chalcopyrite. Gravity wise the tin jumped out and the copper had an 88% flotation recovery to a 36% Cu concentrate and 350 ppm Ag. Comments on variations in head grades for the various samples pointed to erratic mineralization. I suspect if Strongbow have anything there, it’ll be a breeze!<br />Cheers, Stephen Young, Canada<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-40646303203554934742020-04-19T01:09:09.868+01:002020-04-19T01:09:09.868+01:00Thank you, Sir for giving the reply.

Yes made it so clear to me on how to get proper resource and reserve estimates.<br />I am sure such kind of exchanges of views not only help professionals and serve (as I feel) the purpose of Barry's efforts in running these Blogs with so much information.<br />I hope many more take active interest and benefit others in the profession.Rao,T.C.https://www.blogger.com/profile/11160713677908165404noreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-67572439539624452702020-04-18T12:36:11.947+01:002020-04-18T12:36:11.947+01:00No not at all, the assaying will be spot on.

Though I am not a Mining Engineer, I am keen to understand that comment--does it imply that selection of borehole sites was not proper andor/proper chemical analyses was not done on core samples to interpret data to get an indication.<br />May ignore my comment if not put in proper mining terminology.Rao,T.C.https://www.blogger.com/profile/11160713677908165404noreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-91295857657466676172020-04-17T10:28:38.078+01:002020-04-17T10:28:38.078+01:00I'm intrigued with this one, when plotted, the...I'm intrigued with this one, when plotted, the strike of this runs through United Downs industrial, just North of the two GEL boreholes and about 20m South of the most southerly point of the Wheal Maid decline. So GEL missed this by about 10m and Rio Tinto by 20m (30m) total, and the liberalisation width is as much as 16m - that's pretty unlucky by anyone's standards!Anonymoushttps://www.blogger.com/profile/18383105578393948029noreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-77197193000512678922020-04-17T01:54:20.042+01:002020-04-17T01:54:20.042+01:00So nice to get some positive news,Barry.
