Sorry, cant remember who reposted this, I saved it to share with newbies. Thanks again for posting it.
The Beaufort Research Note of 10.07.2017 provides the only indication to date, of potential tonnage for the CS Project, referring on page 7 , to an anticipated pozzolan/perlite deposit of >20Mt (presumably tonne ie US metric ton).
This tonnage was probably calculated using a notional average depth of 5m for the deposit over a total area of 1.58sq km (Main Zone 0.72sq km; NE Zone 0.42sq km and Tuff Zone 0.44sq km) and an average specific gravity (SG) of c2.5 for the in situ pozzolan/perlite source rock.
The latter number of 2.5 SG. is mid-way in the range for rhyolite (ie 2.4-2.6) and is appropriate as an average for in-situ pozzolan (vitrified tephra/tuff) . The Kirkland Mining Co pozzolanic tuff, cited by others on this BB, has a SG of 2.2-2.3, probably reduced due to the 10% non-pozzolanic inclusions.
The data (RNS 03.08.17) from 5 bore-hole cores in the Main Zone and 2 in the Tuff Zone, plus the company online maps and cross-sections, provides a basis, admittedly very limited, for reassessing the Beaufort estimate. The recent 16.10.17 RNS also adds that �the Main Zone remains open to the south, extends further north and east than previously defined and that the Main Zone and East Zone are part of a continuous sequence of adjacent and overlapping zones of pozzolanic perlite and tephra.� This latter statement implies the continuation of a significant thickness of potential source-rock from the Main Zone N and E into the NE Zone as indicated by the A � A cross-section.
Using a 300m grid superimposed on a satellite image of the 3 zones, and the information outlined above, it is possible to estimate the potential source-rock tonnage for each 300m sq block to arrive at totals for the three zones, rounded down to the nearest million. It is important to note however that �source-rock� refers to the total pyroclastic sequence between andesite basement and rhyolite cap-rock. The pyroclastic sequence includes tuffs, tephra, pumiceous ashes, lahars and other lithologies of varying pozzolanic and perlitic quality. Only those portions of the sequence which satisfy all industry tests for use as pozzolan or perlite, which are extractable economically and for which there is a demonstrable market, can be classed as �resource�. The following totals are therefore estimations of potential �source-rock� not �resource�.
Main Zone. 32 million tonnes.
Northeast Zone. 5 million tonnes.
Tuff Zone. 40 million tonnes.
