GTI Energy says it is making good progress towards reporting a maiden Inferred resource estimate by the end of June after acquiring a comprehensive historical data package for the Lo Herma ISR Uranium project in Wyoming’s Powder River Basin.

The Lo Herma data package has been compiled into a drill hole location database and checked against historic location records.

Using mapped redox trends, GTI Energy (ASX:GTR) says drill hole locations, grade information, and an exploration target range has been estimated, along with the preparation of an inventory of bore logs.

The exploration target range, which currently sits at 7.3 to 9Mt at a grade range of 500ppm to 700ppm U3O8 containing an estimated 8.1 to 13.9 million pounds of U3O8, has been reported and the staking of an additional 16.18sqkm completed to capture a greater extent of interpreted mineral trends and historical drilling.

The project has been expanded by 33% to 48.52sqkm and with the digitisation of the original drill data currently in progress, GTR says this information will be used to prepare a mineral resource estimate in line with the JORC code.

Current activities

Geologists are currently compiling a database of stratigraphic contacts for the various host sand horizons that will be used to correlate mineral intercept data once the digitised files are available.

Preliminary steps towards permitting a drilling program at Lo Herma are underway to conduct verification drilling of the historical data, gather information related to the depth of the static ground water table, and strategically target trend & depth extensions of the mineralisation. Environmental and cultural reviews are also underway.

The drilling program is not needed to generate an initial inferred JORC resource using the logs from the data package, but completion of new drilling has the potential to increase the initial resource areas and should also improve the level of confidence regarding the historic data, potentially leading to estimation of indicated resources.

Upcoming activities

Several days of field work are planned, when ground conditions allow, to verify a subset of collar locations that were taken from the maps. Arial geophysics will also been flown within the next month or two.

Once a database of mineral intercepts by sand horizon is prepared, GT contour resource modelling can begin to produce inferred estimates of resource tonnes and average grade.
