Notes
Notes to accompany Mineral Resource Estimate table
- Numbers may not add due to rounding.
- Resource models for the Barranco Option resources, were constructed within the GS3 software, a proprietary resource modelling software developed by Hellman and Schofield.
- The resource model for King Brown, Golden Orb, Battler and Marda Central (Python, Dolly Pot, Dugite, Goldstream, Cobra, Taipan and Green Tree) were constructed using Minesight software. The resource estimates for these deposits utilized a block model with block dimensions typically of 5m by 2m by 2.5m blocks (X, Y Z).
- Block interpolation was estimated using Ordinary Kriging within mineralization wire-frames based upon a ~0.50g Au/t lower delineation cut-off.
- The Marda Central project area is comprised of the Python, Dolly Pot, Dugite, Goldstream Cobra, Taipan, and Green Tree deposits.
- Resource classification has been considered with respect to various reporting ‘modifying factors’ as outlined in the JORC Code (Dec 2004). Consideration has been given to data quality, drilling and sample density, distances of interpolated blocks from assays points and the associated statistical local spatial distribution of gold and estimation variances.
- The Dulcie resource was estimated using Ordinary Kriging within a wireframe of laterite using 20m by 20m by 1m blocks. The resources for all other deposits are estimates of recoverable tonnes and grades using Multiple Indicator Kriging with block support correction into model blocks customised to the average drill hole spacing for each deposit and assuming smallest mining unit for ore selection in mine grade control of 3 metres (across the general strike of mineralisation) by 5 metres (along strike) by 2.5 metres (elevation).
- Resource assaying data sets derived from all available reverse circulation and diamond drill sampling.
- Geology ‘rock mass’ models and interpreted fault or shear zones have been used to constrain mineralisation as appropriate.
- Weathering domains have been used to constrain mineralisation and help assign representative bulk density estimates.
- Bulk densities are based on testwork carried out by SXG and previous companies.
- Data density varies and is reflected in the resource category which has been applied. All measured resources have a drill-hole density of approximately 12.5m x 12.5m. All indicated resources except Dulcie and Battler have a drill-hole density of approximately 25m x 25m. Dulcie has a drill density of 40m x 40m. Battler has a drill density of 20m x 12.5m. Inferred resources have variable density but always less than 50m x 50m except for Mt King which has variable drill-hole spacing between 25m and 100m and the Barranco Option resources which have an approximate drill hole spacing of 100m x 20m and were assigned an Inferred Resource status.
- Assays are generally fire assay, with limited aqua regia assays in the weathered zone.
- All drill-hole collars are surveyed by GPS). Down hole survey data is limited for historic drilling, except at British Hill, where most drill-holes are surveyed. All SXG’s drilling has adequate down hole survey information.
- A lower reporting cut-off of 1.0 g/t Au has been used except at Dulcie where a lower cut-off of 0.4g/t Au has been used.
- The resource estimation for Barranco Option resources was by polygonal cross-sectional methodology with the mean of all assays within a polygon used as the calculated grade.
