Ann: Exceptional 99.1% TGC purity Achieved-BKT.AX, page-19

hi Destria

the 'high purity recoveries' would not effect the resource size since the 'higher purity' is a product of creating more waste from the ore (since the more the graphite flakes are grinded, the higher the purity)

a currently unknown factor that is important is "yield" from spheronising. the last quarterly report says: BKT is currently doing test work to determine the suitability of Mahenge concentrates to produce spherical graphite, expandable graphite and commercial scale graphene. therefore, a spheronising announcement about battery grade graphite & also anode production may be due in the near future, similar to the links below:

battery grade sphercial graphite: http://www.asx.com.au/asxpdf/20141120/pdf/42tv9y6txgsy0r.pdf

yield: http://www.asx.com.au/asxpdf/20151111/pdf/432wwmrm1z80r0.pdf

anode: http://www.asx.com.au/asxpdf/20150114/pdf/42vzr7180wtbv1.pdf

BKT are drilling now to upgrade the resource to 'measured-indicated'. i would guess a resource upgrade would be due in July or August at the latest

the last quarterly report states for this current quarter: "Completion of the bulk of the Pre Feasibility Study activities". therefore, the PFS looks close to completion, probably no later than September. The report on the BKT website states: "Pre-Feasibility Study (PFS), aimed for completion around August 2016. "

the last announcement was a huge unexpected surprise & indicates BKT are working very diligently
