BUTCHERBIRD (100%)
The Butcherbird Project straddles the Great North Highway approximately 120km south of Newman. Work to date has identified both copper and manganese mineralisation and work is ongoing to assess the commercial potential of these discoveries and to explore for additional deposits within the province.
BUTCHERBIRD MANGANESE
The Butcherbird Project hosts the largest onshore manganese occurrence in Australia and is further enhanced by its location which straddles the Great Northern Highway and the Goldfields Gas Pipeline.
The manganese mineralisation at Butcherbird occurs in shallow flat lying zones with the ore occurring as discrete high grade bands interbedded with clay waste. These zones are often overlain by a cap of high grade ore which is being targeted as potential DSO material.
The style of the mineralisation at Butcherbird is amenable to relatively low cost beneficiation which contributed to the positive outcome of a Scoping Study completed in 2011.
Feasibility Studies have commenced with aim of confirming the viability of the deposits to provide substantial tonnes of commercial grade manganese oxide ore for export. Production is envisaged in two stages; Stage 1 will exploit the DSO ore identified at several areas within the project, commencing at Bindi Bindi Hill. Bulk sampling studies completed in the previous quarter have demonstrated that the DSO material can produce a high grade concentrate in excess of 40% Mn. Stage 2 will target larger scale production (0.5-1.0Mt p/a) from the larger benefeciable zones of mineralisation at the various resource areas.
Project Manager Appointed
To facilitate and accelerate the various ongoing environmental, Native Title, engineering and related studies required for mining approval applications, the Company has appointed an experienced Project Manager, Mr Mike Moore (B.Eng (Hons), MAusIMM, Dip CSM, ACSM).
Mr Moore is a mining engineer with 15 years’ experience from operations in Australia, South Africa, West Africa and Europe. His previous experience has included:
-
Managing the establishment of a new mining operation in West Africa and holding a board position with Carnegie Minerals Gambia Ltd;
-
Contracts management with mine service providers in the drilling and blasting sectors; and
-
Project management for resource and mine contracting companies.
Mr Moore has worked in open pit and underground mining operations including iron ore, gold, zircon, diamonds, tin and copper.
Mining Approvals
Mining Lease applications have been lodged for the DSO ore at Bindi Bindi Hill, as well as a number of Miscellaneous Licence applications to accommodate associated infrastructure including, but not limited to haul roads and water bores.
A number of studies have or are about to commence at Butcherbird with the aim of collecting and analysing the information required to support mining approval applications, primarily in relation to the proposed DSO production operation.
Studies that have commenced or are due to commence in the coming quarter include:
-
Native Title Negotiations;
-
Fauna vertebrate surveys;
-
Subterranean fauna surveys;
-
Hydrology;
-
Flora Level 2 survey; and
-
Approvals Regulatory Submissions and Management Plans (Bindi Bindi Hill).
Infill Drilling Programme
During the Quarter, the Company completed an infill RC drilling programme covering two areas of the Yanneri Ridge deposit which have been identified as potential start-up pit areas. A
total of thirty eight holes were completed for 1,140m which brought the drill spacing in the targeted areas down to 100m X 100m.
Once all drilling data and Quality Assurance/Quality Control information has been compiled, the JORC Resource Estimate for the Yanneri Ridge deposit will be reviewed and upgraded as appropriate.

BUTCHERBIRD COPPER
During the quarter, an RC drilling programme was commenced at the Company’s 100% owned Butcherbird Copper Project. The total programme comprises twenty two RC drillholes for a total of 5,640m. The drilling was designed to further test the copper prospectivity of the Butcherbird Shear Zone along a target corridor in excess of 6km in strike extent.
==> picture [271 x 199] intentionally omitted <==
Whilst the programme has suffered from rain induced interruptions, the partial results to date have further extended the strike of copper mineralisation. Drilling has now confirmed the high grade copper mineralisation discovered in 2011 over at least 600m in strike, open along strike and at depth. Mineralisation widths and grades generally appear to improve with depth.
Mineralisation occurs in a number of lithologically and structurally controlled positions within a >6km striking corridor along or adjacent to the Butcherbird shear zone. Previously drilling by Montezuma confirmed the presence of significant copper sulphide mineralisation and subsequent work has now confirmed the discovery as a significant copper mineralised system with excellent upside potential.
Prior to the rain event which temporarily disrupted drilling, ten RC Drillholes were completed for 2,112m. Notably, the best intersection from the recent programme, BBRC00220, is the easternmost hole completed to date.
The drilling and field crews have now remobilised to site and recommenced drilling with approximately 2,000m remaining to be completed in the currently planned programme, with further holes being planned.
In the interim, detailed geological and structural analysis of results to date will commence to better understand the distribution of copper mineralisation within the highly prospective Butcherbird shear zone in order to optimise the targeting of the next round of drilling.
Follow up work is likely to comprise a programme of extensional drilling as well as an infill programme to better define the geometry and geological controls on mineralisation within the system. Additionally, sporadic lead and zinc anomalism has been identified in certain zones and this will be investigated as a possible pathfinder to high grade copper mineralisation.
