Peninsula Minerals' high grade drill results add to Ross uranium resource
Peninsula Minerals (ASX: PEN), a uranium developer and explorer, has completed 35 development drill holes during the first weeks of May for a total of 22,129 feet at its Ross Uranium project.
Ross is part of the Lance Projects, located on the north-east side of the Powder River Basin in Wyoming, USA.
The company said the intention of the current drilling has been on enhancing the grade and definition of the existing resource and to progress inferred resource to indicated status.
Results include:
- Hole RMR0358 intersected 19.5ft @ 2,090ppm U3O8 from 477.25’ to 496.50’GT 4.08;
- Hole RMR0347 intersected 19.5ft @ 340ppm U3O8 from 447.25’ to 466.75’ GT 0.66; and
- Hole RMR0349 intersected 23.5ft @ 270ppm U3O8 from 475.75’ to 499.25’ GT 0.63.
The highlight of these results was drill hole RMR0358 which intersected 19.5ft @ 2,090ppm U3O8 (GT 4.08), including a peak intersection of 6ft @ 3,120ppm U3O8 within a newly interpreted mineralised roll front.
Peninsula said three drill rigs are currently engaged at Ross testing extensions of the known exploration target zones identified by the modelling software while a fourth rig continues to test sparsely drilled target zones, with the aim of expanding the current 15,100,000 lb U3O8 JORC compliant resource.
Gus Simpson, executive chairman, said “now that we have modelled all geological and drill data the development team is able to accurately target the nose of the ore zones and they are bringing home the pounds.”
During May Peninsula has completed 35 drill holes at Ross, of which 22 holes encountered significant mineralisation. A total of 10 holes recorded multiple stacked intersections of uranium mineralisation.
The company said the focus of the drilling in May has been predominantly within the exploration target zones in Sections 18 and 19 as shown in Figure 1. Infill drilling will now be focused on the interpreted roll fronts, highlighted by an intersection of 19.5ft @ 2,090ppm U3O8 (GT 4.08).
In addition there are extensive exploration target zones yet to be tested in Sections 19, 13, 12 and 7. Three rigs are currently operating to expand these mineralisedsystems while a fourth rig continues to test for extensions of mineralised trends into the sparselydrilled Section 13, which, if successful, will add directly to the existing resource inventory.
Simpson said "Peninsula anticipates that by adopting the Grade Thickness method for the definition and reporting of reserves as well as for practical mine planning and production purposes there may well be an up lift in the total recoverable pounds of uranium."
