Uranium
Gold Road Resources holds the following uranium-prospective tenement portfolio:
- Thatcher Soak
- Lake Wells
- Lake Rason
- Golden Sands
Gold Road's Thatcher Soak uranium project is located approximately 150km north-east of Laverton in Western Australia within granted exploration licences E38/1083 and E38/1388. The adjacent tenements, containing the western portion and potential extensions of this deposit are held and actively explored by Uranex NL ("Uranex").
Gold Road holds a 100% interest in the Project, with mineralisation extending to the west into Uranex's tenements.
Gold Road announced its maiden uranium resource for the Thatcher Soak Project in 2008. The total length of uranium mineralisation at Thatcher Soak is approximately 15km.
The Thatcher Soak uranium mineralisation is principally carnotite with the mineralised zones elongated parallel to the drainage and largely coincident with a playa lake system. The mineralisation is usually shallow and 1m to 2m thick.
The resource was estimated using Ordinary Kriging of geochemical and factored radiometric assays within wireframes that formed the constraints for the block model constructed by Coffey Mining.
Iron Ore
Aero-magnetic signatures suggest a banded iron formation (BIF) extending over 80km within the Yamarna tenements. Inspection of the available outcrops indicated a strongly magnetic 1m to 40m wide magnetite banded iron formation. The historical data investigation suggested that very few drill holes targeted the iron formation and none were assayed for iron as the main exploration objective was for gold.
Molybdenum
Soil geochemistry at Yamarna has identified anomalous molybdenum values. A western 1km-long lead-zinc-copper-arsenic (up to 0.14% Pb) anomaly is associated with sporadic but elevated gold. The base metal anomaly coincides with an outcropping sulphide-rich alteration zone and is located approximately 200 metres west of the gold anomaly.
Nickel
Gold Road Resources has carried out studies to assess the nickel sulphide and chromite ore potential within the Yamarna greenstones. The initial study indicates that any Ni-Cu sulphide mineralisation within the Yamarna Greenstone Belt is most likely to be hosted by komatiite ultramafic rocks.
Data on the ultramafic rocks within the Yamarna Greenstone Belt is very limited with most of the useful data located around the chromite mineralisation.
Data from geological maps, drill logs, assay data and petrographic descriptions strongly suggest that the ultramafic sequence that hosts the chromite mineralisation at Yamarna South is the basal zone of relatively thin, but laterally extensive (>80km) layered mafic/ultramafic unit probably a sill.
Six of the highest priority magnetic targets have been delineated for ground EM or/and airborne VTEM in order to locate nickel sulphide conductors. Ground rather than airborne EM is preferred over targets that require penetrating through deep cover. The Company is actively seeking JV partners for its nickel projects.
Chrome / PGE
Yamarna chromite prospect located 2km west of Attila gold deposit. First pass RC completed by Gold Road over strike length of 500m, with multiple chromite seams intercepted.
The aeromagnetic data indicates that several other magnetic olivine cumulate units (and the magnetic gabbroic units to the east) may occur at irregular intervals along the trend, to date none of which have been effectively drill tested.
Results of Gold Road Chromite Drilling include 6m at 32.9% Cr2O3, and the Company considers there to be substantial potential to locate additional chromite mineralisation at Yamarna.
