VII 2011 – Rogerley, Penny`s Pocket!

 

 

   The last few weeks were very busy for our team. Parallel with publishing Minerals #2, and editing the book “Agates from Ploczki Gorne, Lower Silesia, Poland” we were working on Mindat.org Conference and preparing for Sainte-Marie-Aux-Mines show. Finally everything went well, but at the end of the Conference I was really exhausted. I was dreaming about some real holidays – somewhere with no hurry – either under or over ground collecting. A great opportunity showed up just before end of Conference – Cal and Kerith Graeber invited us to visit the Rogerley mine again! Reason was simple – they just hit a new pocket which produced several good quality specimens. They still didn’t know much about overall size and quality of pocket. We decided immediately to go and 5 days after Conference we – Scott, Kristof and myself were in Northern England. Unfortunately for us, Asia was enjoying the beaches in Croatia,  so the photography portion of this report is not up to normal standards. It was difficult to take pictures while playing in the mud!
   The last year was very hard for UKMV team – they lost their good friend and main miner, in addition to not hitting any important pockets etc. This year was kind of an „exam“ for the mine – they were even thinking about leaving project! Fortunately in the middle of season they hit a new pocket, which will perhaps prolongate mine activity.
   The pocket was named „Penny’s Pocket“ in the honor of Penny Williamson – Curator of Geology, University of Wollongong, and Vice-President of Society of Mineral Museum Professionals from Australia. She had just visited the mine when pocket was found! She stayed there only a few days, so probably before reading this report she didn’t know how good Penny’s Pocket really was!
   During our stay it was shown that pocket is about 4-4,5 meter long, and at least 1 meter deep. Hopefully with additional work it will produce more specimens and we especially hope that it will be much deeper than it was when we had to leave. Penny’s Pocket, as all important pockets in Rogerley, is brecciated and filled by mud. In general there are 2 kinds of mud – a soft clayey one and a hard calcified one. All crystals are frozen in one of these two kinds of mud and have to be extracted very carefully. Unfortunately, a majority of specimens were previously damaged during a brecctiation episode. Fragments of breccia are from a few centimeters to over a meter in size. The majority of them do not have crystals on surfaces. Only in select horizons do blocks occur partly coated by crystals. The biggest specimens reach almost a meter but they need serious trimming to become a really good specimen. Size of crystals varies from a few millimeters to about 3-3,5 cm on an edge. The majority of crystals are twinned, with good or medium luster, very gemmy and with incredible daylight fluorescence (the best possible). They have growth hillocks typical of Rogerley fluorite. Untwined crystals are quite rare and usually not very good quality. The biggest fluorite collected during our stay was about 4 cm on edge.
   During collecting we discovered one very unusual block partly covered by small and partly by big fluorite crystals. Shape of the block retains the shape of a coral colony, and some of us suspect that maybe this is hydrothermally prepared coral later overgrown by fluorite!
   Our team spent 5 days in Weardale, each day working in the mine. During our stay Cal had a lot of problems with machinery and although he used us as a scapegoat (as it started just when we arrived) – you can trust me that we are last persons to make sabotage in this great mine :-) ! Fortunately we brought good weather with us from Mindat.org Conference and during whole our stay there was not any rain and quite a lot of sun (by Northern England standards). One of the days was interspersed by visit of two friends – Jurgen Tron (Germany) and Mark Kielbaso (USA) (by the way „sausage“ in Polish language!). Surprisingly they were quite relaxed, especially Mark who stayed in the mine for only a few hours and then went with Jurgen to nap in the sun! That was quite funny comparing with his fame as a digger and miner in serious minerals projects. I saw that Scott for while wanted to join his „lazy team“ but hopefully we prevented his tendency to laziness...
   Evenings we spent (of course) in the famous Blue Bell pub tasting great local beers and whiskies. One day we also made a short tour to see remains of famous mining operations in the area. However some invisible force pushed us quickly back again to the Rogerley mud.
   Altogether we spent a great time with friends, mud and fluorites. Of course self-collecting world-class specimens is an unforgettable experience, as is bringing them for the first time to daylight where they show incredible blue color (daylight fluorescence). During our stay we had the chance to collect many specimens,  several of which were really good and unusually big. Cal and Kerith, thank you very much for the invitation! These were the best holidays you can imagine!

Great site report as always--thanks for bringing the mine to us armchair enthusiasts! Scott, I`m very envious! Couple of questions/comments:

Did I see a 2nd portal (with an arched profile) under the staging area to the upper portal? What`s the story with that portal?

I have to say I winced a bit at the photo of Cal sitting on the saw. All I could think of was one slip and there go the family jewels...

Perhaps we`ll meet at one of the shows if you ever make it state-side, Tomasz.

Regards, John

Hi!
I am happy you liked the report, I am not sure if I understood your question well, but the lower entrance to the mine was the first one - beacuse the upper zone is more productive the mine was mooved there. You can find a detailed story in the article about rogerley in Minerals #2 - http://spiriferminerals.com/92,MINERALS---The-Collectors-Newspaper--2.html (or pick it up in Springfield/Tucson/Denver from Scott).
I hope to make it to Tucson next year so hope to see you there!
Best regards,
Tom

Tom,

Very interesting, to have the opportunity to collect in the Rogerly mine must be a pure treat. Someday I would love to be able to collect in the types of localities you get to. Makes me jealous! Fine specimens you collected, someday I would like to get something of that quality, almost makes me want to send all of my specimens to the crusher (not the halite I got from you though, it is great!) Keep up the great reporting on your collecting. Send me a wish list from Missouri`s Viburnum Trend, still owe you a few specimens, let me know what your interestedd in.
Sincerely,
John L. Dolde, PG
