Natural Gamma Ray Spectrometry confirms high polyhalite content in the two key massive polyhalite beds

The Directors of Sirius Minerals Plc (AIM: SXX, OTCQX: SRUXY), the globally diversified potash development group, are pleased to announce the completion of the wireline logging of its first borehole ("SM1") at the York Potash Project.

Following the completion of coring of SM1, announced on 27 October 2011, Schlumberger conducted a series of geophysical wireline logging tests on the hole. These tests included natural gamma ray spectrometry, density, neutron and sonic logging to assist in mineral identification. Spectral gamma ray tools resolve the natural gamma ray spectrum into its different components, including potassium; and so can be used to estimate approximate potassium contents in the borehole.

The Upper and Lower beds of massive polyhalite identified in the 27 October 2011 announcement, representing a combined 19 metres (true thickness) of massive polyhalite, gave average gamma readings across the whole of these intersections attributable to potassium that equates to polyhalite grades in excess of 80%. Within these thick mineralised zones there were certain zones of significantly higher than average grades apparent. These estimations of polyhalite grade align with the field assessment of the massive zones as having low levels of visibly identifiable halite and anhydrite inclusions.

It is very important to note however that full chemical and mineralogical analysis is required to confirm the grades and continuity of the potash mineralisation in the recovered core. These are expected in approximately four weeks, as advised in the announcement on 27 October 2011.

another rns with more fantastic news - yeeeeeeeeeeeeehaaaaaaaaaaaaaaaa

Natural Gamma Ray Spectrometry confirms high polyhalite content in the two key massive polyhalite beds

up again i note - volumes flying - and not surprised!!!! and its not in some war torn country in the middle of no where - yeeeeeeeeeeeeeeeeeehaaaaaaaaaaaaaaaaaaaa

volumes very high 4.5m + last 45 mins - best of the day and latest recent rns releases - kerrrrrrrrrchinnnnnnnnnnnnnnggggggggggggggggggggggggggggggggggg

and lunch time rush due shortly

lol wonder if bhp or another will make an offer - potash a rare commercial volume commodity which china needs as much as it can get and other countries of course!!!

A small mention here.

Jobs bonanza predicted after 143m RGF boost

good stuff skinny - locally it is massive news

but the better news is that the iis have sat up and taken notice again - interesting day ahead

significance of rns sinking in me thinks - on course for massive volumes all day currently

incredible - very strong buying should tick again soon

ticking nicely

Too far, too fast. At some point this will consolidate, but looks to be a good investment for the future, imo.

hopefully after 20p reached - cheers

however if the buying continues like this 20p will be smashed

.

final push - yeeeeeeeeeeeeeeeeeeeehaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Briefly breached 20p. Soon time to take profit, maybe?

you took the words out of my mouth hc - this is good

Just sold half here for just shy of 100%.

well done skinny

did similar - shoved some into barc!
