Bimurra Project Perseverance-Elizabeth Exploration Target
ASX Announcement 21 September 2015
GBM Identifies Significant Gold Mineralisation at Bimurra Gold Project, Mount Coolon Gold Mines
-
Extensive gold mineralisation confirmed in historical data within the Bimurra Hydrothermal system.
-
The exploration potential for the Perseverance-Elizabeth area has been quantified after modeling of gold mineralization in multiple zones over a 500 metre strike length.
-
An Exploration Target range for the Perseverance-Elizabeth area of the Bimurra Prospect of between 10 million tonnes at an average grade of 0.7 g/t Au containing an estimated 230,000 ounces of gold and 4 million tonnes at an average grade of 1.2 g/t Au containing an estimated 120,000 ounces of gold has been estimated.
It should be noted that the potential quantity and grade is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
-
GBM continues to process a large quantity of data and has identified other prospects which may host additional oxide and sulphide mineralisation.
Australian resources company GBM Resources Limited (ASX: GBZ) ('GBM' or 'the Company') is pleased to announce that a review of the exploration data available has identified extensive gold mineralisation at the Bimurra Gold Prospect, part of the Company's 100% owned Mount Coolon Gold Project, located near Charters Towers in Central Queensland.

Executive Chairman, Peter Thompson said the review had confirmed GBM's expectations of the gold potential at Mt Coolon.
'We believe that the Mt Coolon Gold Project area has the potential to host large scale gold mineralisation, and we have yet to fully analyse the large quantity of exploration data that we believe has the potential to identify other prospects that may host additional oxide and sulphide mineralisation. It certainly has the potential to be a significantly large mineralising hydrothermal system and we intend to investigate it in its entirety.'
Bimurra is a separate prospect area to the three main deposits (Eugenia, Koala and Glen Eva) which contribute to the Resources at the Mount Coolon Gold Project which were recently upgraded to comply with the guidelines of the JORC code (2012 edition) - refer ASX release 27 August 2015. These resources contain a total of 268,600 ounces of gold.

Mineralisation
The Bimurra Prospect is located in the Drummond Basin, approximately 200 km inland from the coastal town of Mackay in Queensland. The Drummond Basin has been a major gold producer since the recognition of the significance of epithermal mineralising systems lead to the discovery of a number of gold deposits in the area in the 1980's including Wirralie, Pajingo and Yandan. A gold endowment in excess of 7 million ounces has been identified in the Drummond Basin to date.
The Bimurra Prospect represents a large mineralising hydrothermal system (The Bimurra Hydrothermal System) hosting numerous prospects and mineral occurrences, almost all fit into the styles generally associated with epithermal low sulphidation mineralising systems. Previous explorers have identified and named nine gold prospects; Blenheim, Hilltop, Perseverance, Elizabeth, Bimurra East, Camp Creek, Ramillies, Bungobine Peak and Bimurra North East. In addition, a number of conceptual targets have been identified based on structural interpretation, soil and rock chip geochemistry. The area is also dotted with occasional unnamed pits and shafts from previous prospecting activity.
GBM is in the process of locating and compiling data from previous explorers and to date have assembled a data set which includes analyses, survey information and geological data including 9,285 samples from 130 drillholes. Initial interpretation and modelling is now well advanced for the main Bimurra mineral occurrence, which includes the Perseverance and Elizabeth zones, the two most intensely tested areas by previous explorers. Detailed mapping has identified numerous continuous and semicontinuous zones of chalcedonic quartz veining, stockwork and brecciation. Rock sampling and drill testing, both Diamond and reverse circulation percussion, has confirmed that gold mineralisation continues to depth and over significant strike lengths.
Intercepts of the Perseverance Zone include a number of quartz veins with 0.5 - 4 metre widths and moderate gold grades in 5 - 10 g/t Au range (most notably in PDHBIMS23, PDHBIMS28, and PDHBIMS32). Veins occur within envelopes of discontinuous low grade stockwork with widths up to 100 m and grades in 0.3 - 3 g/t Au range (PDHBIMS25, PDHBIMS39, PDHBIMS14). See table in appendix for detailed summary of historical drill intersections.
The Elizabeth Lode breccia, to the south of the Perseverance lode is approximately 250 m long and 40 metres wide and represents an excellent exploration target that remains widely untested by previous drilling (Tate, N.M., 2001). Hydrothermal breccias, such as that found at Elizabeth Lode were not recognised as economically significant by previous explorers and were apparently too low grade at surface to attract historical miners. However, previous work by Delta Gold Limited identified the potential of these zones, particularly when associated with major structures (Bungobine Anticline), as they represent large zones of very high fluid flow on and consequently indicate substantial potential for bonanza type breccia and lode style mineralisation at depth. The predominance of chalcedonic silica and quartz textures in the breccias are exposed well above the zone of gold deposition in typical epithermal systems. Potentially high grade bonanza gold mineralisation is likely to commence at depths of 100-300 m below the present surface (Tate, N.M., 2001).
Exploration Target for the Bimurra Prospect
Previous exploration results for the area historically referred to as the Bimurra Prospect (including the Perseverance Lode and part of the Elizabeth Breccia) has been compiled and a preliminary three dimensional model created encompassing a series of broad zones of gold mineralisation and associated quartz veining. This model was created to allow the near surface potential (maximum depth of model is 180 metres below surface) of the area to be evaluated as an exploration target. This model is intended only to provide an estimate of the potential of these two prospect areas. The model utilises broad search radii of up to 200 metres where supported by indications of geological continuity of the zones, but where drilling density would not otherwise permit grade estimation and is neither rigorous or detailed enough to be considered a resource estimate. The estimate utilised the 3D Discover software voxel process (Inverse Distance weighting). The total Voxel volume was checked against the volume of the 3D model and was in agreement to less than 10 % which is considered sufficient for estimation of an exploration target.
Based on the model an exploration target range has been selected which reflects the uncertainty in a number of areas with broadly spaced data, and also the alternative ways in which the deposit could be modelled i.e. higher grade lodes verses broad lower grade stockwork or vein zones. The target range is highlighted on the pseudo- grade tonnage curve produced by applying an assumed specific gravity of 2.5 t/m3 to the output volumes from the voxel model.
GBM have estimated an exploration target range for the Bimurra mineralisation of between 10M tonnes at an average grade of 0.7 g/t Au containing an estimated 230,000 ounces of gold and 4M tonnes at an average grade of 1.2 g/t Au containing an estimated 120,000 ounces of gold. It should be noted that the potential quantity and grade is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. It should be emphasised that this target estimate does not consider the potential for bonanza grade veins or shoots to exist in the Bimurra Prospect either near surface, or at depth.

Forward Programme
Completion of detailed data base compilation for the Bimurra area is expected to lead to estimation of a mineral resource for the more intensively drill tested portion of the Exploration Target area. This will be completed in conjunction with compilation of data from other deposits in the area which may hold potential for additional resources to be added in the near future based largely on historical work. Other proximal GBM prospects with potential include Wobegong and Red Flag Hill. If drill core from previous programmes can be located, check sampling, character sampling and petrography will also be completed to assist in understanding the system level that is exposed at Bimurra. Previous workers have indicated that the observed mineralisation is high in the epithermal system and that potential for bonanza grade veins may exist at depth.
In addition the Company is investigating options to fast track other prospects at the Mt Coolon Gold Project to gold production. Quotes for a scoping study to evaluate the feasibility of commencing a heap leach operation to extract gold from oxide resources at Eugenia are currently being considered.
Background to Mount Coolon Gold Project
In January GBM announced the signing of a binding Share Sale Agreement ('SSA') with Drummond Gold Limited (ASX: DGO) pursuant to which GBM would acquire a 100% interest in all of the issued capital of Mt Coolon Gold Mines Pty Ltd. This transaction was completed during April (see ASX release dated 13th April 2015). The project is located 250km west of Mackay in Queensland in the northern Drummond Basin. The Drummond Basin is an established gold mining region with past production of more than 4.5 Mozs and a total known gold endowment of over 7.5 Mozs of gold. Deposit styles range from bonanza grade epithermal veins (eg. Pajingo 3.0 M ozs) to bulk tonnage intrusive related gold deposits (eg. Mt Leyshon 2.1 M ozs).

Sampling techniques
|
-
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.
|
-
A total of 130 holes for 19,142.35 m have been drilled at Bimurra. Drilling includes a total of 38 DD holes for 7829.75 m, 63 PERC holes for 6112.6 m & 29 RC holes for 5200 m. Samantha drilled 2 DD holes for 339 m, Kenecott drilled 4 DD holes for 604.5 m, Geopeko- Menzies drilled 22 DD holes for 4737.79 m & 27 PERC holes for 3046 m, BHP drilled 1 DD holes for 198.5 m & 36 PERC holes for 3066.6 m, Perilya drilled 11 RC holes for 1866 m, Ross drilled 9 RC holes for 2040 m and Delta drilled 9 DD holes for 1949.96 m & 9 RC holes for 1294 m.

-
The sampling techniques used by all previous workers are similar to, or in line with GBM Resources Limited standard operating procedures for exploration drill product logging and sampling and are of a standard sufficient for resource estimation, where methodology is not clear in the database historical reports and documentation has been reviewed to ensure care and diligence was adhered to. Where drilling methods such as Rotary Air Blast (RAB) have been used, these holes have been excluded from resource estimation.
-
Diamond core was recovered in a standard wireline core barrel with inner split or 'triple' tube. Samples were pushed out from the core barrel, with the top half split was split and the core placed in a core tray of suitable dimension.
-
At all stages of drilling where Reverse Circulation (RC) or Percussion (PERC) drilling methods were employed, samples have been collected via either a rig mounted or standalone riffle splitter via a rig mounted cyclone.
-
Down hole camera shots were checked using visual and graphical representation.
