Drill holes are generally on an angle YT!The ann doesn't say what, but I guess 60 degrees ish.... Just a pluck. By the maps they provide definately not 90. So, future drilling maybe directly down (90 degrees) or at a greater angle in the direction perpendicular of the ore body to capture it at shallower depth. (30 degrees maybe ) I'm no drilling expert!! Someone set me straight please!
I've gone back through Granges early anns on Southdown and some of their early drill holes didn't hit mineralisation until 150m. If it is an extension of the same deposit, then the mineralisation looks to start under 20-50m of cover and extends to 300m depth. Hopefully MAK's is the same.So you reckon they came from outside the orebody, on say a 60 degree angle and only uintersected it at 120m's? Makes sense I guess,
Buenas, Amigo YT!Hey Kennarico,
Thanks for the info, makes complete sense to me now, its a very easy way of understanding the deposit extension, MAK maybe onto something here!
Tassie U surface assays look pretty interesting, the MD calling the deposit to be potentially economical, before they've even drilled.
Average assays 14lb/tn sounds pretty good?
Any thoughts?
Not sure of Tassies stand on U mining still....
Hey Kenna,
Tassie U does look interesting, but like you I have no idea what Tassie stance on U is,
Opies doing well I see
Yes, Tassie is a 'green' state but it hasn't stopped the NW corner of the state slowly being turned into one huge mine. There's numerous operators and new mines being developed as we speak. The question of whether U is a 'green' fuel, or a world destroyer is the question perhaps.I don't know what the chances would be of getting a mine going thanks to being the green state. Anything that isn't green causes a lot of controversy here and the greens have more power here than anywhere else in Australia.
Australia's Apple Isle gets a taste for uranium
When Australia was enmeshed in the 1950s Cold War and strategic metals such as uranium were sought, there was one shortlived quest in Tasmania but Minemakers Ltd now is intent on taking forward the first modern uranium search on the Apple Isle.

PERTH -
Minemakers Ltd, an explorer with a diverse set of commodity targets on prospects in the Northern Territory, Western Australia and Tasmania, now believes it has at least one significant uranium target in Tasmania.
Tasmania has been absent from the pegging rush for uranium prospects in Australia, however, Minemakers has some distinctive uranium targets to evaluate on its Rossarden prospects that takes in the Storeys Creek tungsten-tin project, mined in the past by two companies.
The company's managing director, Andrew Drummond, told Mineweb that historical records showed six significant uranium occurrences in Tasmania and five of these are on Minemakers' tenements.
One prospect explored by a company set up in the 1950s, Tasmania United Uranium NL, contained high grade mineralisation, with past assays as high as 13.6% U308 (300 lbs/tonne).
This mineralisation was in a fault zone and was followed underground for 27 metres and there was evidence that limited drilling went no further than 50m.
At the Castle Carey zone, records showed there was potential for a large deposit of medium grade uranium that was discovered in a black shale stratigraphic unit 2-3m thick and contained in a fault-bounded block about 6 kilometres x 700 metres in extent. The company said limited past trench sampling at Castle Carey indicated grades would be about 0.1% or 2.2 lbs/t U308. "In the mid 1950s that grade was not economic but is potentially so at today's uranium prices," the company said.
Drummond said field work on Tasmania United may not be restricted to being a high grade deposit in a fault zone as there was evidence that a larger alteration zone contained significant uranium mineralisation.
Minemakers is now developing a drilling programme on Storeys Creek for tungsten and tin and on two of the separate uranium targets.
Drummond said the Rossarden licences provide the same sort of opportunities that explorers had venturing into the eastern goldfields of WA in the 1980s when the focus for targets below mainly shallow workings was enormous.
Prospectors worked alluvials in the wolframite and cassiterite deposits at Storeys Creek and adjacent deposits in the Rossarden district from 1892 and the last operator there was Aberfoyle Ltd before it was taken over by North Ltd, in turn acquired in the late 1990s by Rio Tinto plc.
You would have to consider that if they define a resource here of any decent tonnage, that GRR/Sojitz will farm in and add W Southdown to the Southdown project. All the infrastructure will be well on the way by the time a JORC is finalised and they just plug it in. As long as the deposit is close to surface it looks pretty positive.MAK ann out late Thursday....release of Fe assays for Southdown.
Southdown iron project potential must be being watched by GRR...and potential partners.
