Preliminary Coring Results.

81.8 metres (true thickness) of total potash mineralisation across all three seams with the hole being terminated while still in polyhalite mineralisation;

All three potash seams successfully cored;

65 metres of polyhalite (potassium sulphate) mineralisation within the Fordon evaporites including two zones containing a total of a 19 metres (true thickness) of massive higher grade polyhalite;

7.8 metres of the Boulby potassium chloride seam;

9 metres of the Sneaton potassium chloride seam; and

~100% core recovery.


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

Chris Fraser, Managing Director and CEO of Sirius Minerals, said:

"Although preliminary, these are fantastic results for Sirius. The confirmation of all three seams in exceptional thicknesses is a validation of the world-class status of the project. We are all looking forward to the completion of the chemical assays to confirm the grade of these potash zones. Of particular excitement is the 19 metre thickness of massive polyhalite. This compares very favourably to the 5 metre thickness assumption used in the previously announced Exploration Target.

"The first hole we have drilled in the York Potash Project has delivered one of the world's single thickest potash intersections ever reported."

The market certainly likes the news, up 2 points with 35 million shares traded

Yes and excellent volume.

sp Looking good...now 160% up ...will keep holding..alot more to come.. (imho)

checked in half mine may this morn bank rest later today if rise continues - next results 3/4 weeks which should be v good - back in again b4 then if i sell all today

well done to all

yeeeeeeeeeeeeeeeehaaaaaaaaaaaaaaaaaaaaaa

Certainly on a tear this morning!

what a great monday - massive volumes - yeeeeeeeeeeeeeeeehaaaaaaaaaaaaaaaaaaaaaaaaa

wow volumes increasing!!! good day ahead not even 9am yet!! gla

heading for 20p + easily

ah profit taking (gl) has delayed the 20p - but volumes still nice and high!!

.

nice 1 hc

Wireline Logging Update

Wireline logging of SM1 successfully completed
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.

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
