Bullabulling Gold Project - February Project Update
8 February 2011
GGG Resources plc is pleased to announce a project update on its Bullabulling
project, the former producing gold mine in the Coolgardie Goldfield of Western
Australia. The update includes results from an additional 29 drill holes of the
current resource drilling programme. Bullabulling is being re-developed by the
Company with its joint venture partner, Auzex Resources Limited.
Highlights
* Latest drill highlights indicate all 29 new drill holes were mineralised
including:
18m at 4.37 g/t Au from 53m in BJ0057,
4m at 3.30 g/t Au from 42m in BJ0084,
5m at 8.20 g/t Au from 23m in BJ0085.
* To date 87 of 88 holes show mineralisation consistent with the current JORC
resource model
* 22% of mineralisation in the current programme extends beyond the current
JORC
* JORC resource model upgrade on track to be reported in Q2 2011
* Additional 7km of drilling commissioned on top of the existing budgeted
17km
* Metallurgical drilling has been completed ahead of schedule and preliminary
results indicate material is softer than expected
* New prospecting licences were added to the existing tenements for a total
of 144km2
Jeff Malaihollo, Managing Director of GGG Resources, says:
"Results from the drilling continue to increase our confidence in the quality
of the historic data and the accuracy of the resource model. We have now
commissioned a further 7kms of new drilling in order to infill the new
mineralisation we found outside of the historically drilled areas. If the
results are consistent with the rest of the deposit, we expect to include these
zones in the new resource estimate to an Indicated Resource category. We are
also delighted that the metallurgical work indicates a softer material than
expected. Although at an early stage, this may have a positive impact on the
project by lowering mining and crushing costs and therefore enabling us to use
a lower cut-off grade."
Geological Review and Drilling:
The Joint Venture is pleased to announce an update on progress to date on work
at the Bullabulling Gold Project. Work in the period after Christmas has
focussed on completing the resource drilling, reviewing QAQC results, reviewing
drill spacing requirements to upgrade the new resource estimate and completing
metallurgical testwork.
The Bullabulling Gold project is a large tonnage, low grade deposit with high
grade shoots, associated with the regional Bullabulling shear zone which
extends over tens of kilometres. The current programme focuses on approximately
2.3km of the 6km portion known as the Bullabulling Trend which was previously
mined by Resolute Mining. The focus for the Joint Venture is to establish an
initial reserve to commence production in 2013. Mineralisation is open in all
directions, and it is planned to follow up new exploration targets once the
current programme is completed.
Resource Drilling
A key objective of the resource drilling programme is to compare results from
the historic drilling to improve the confidence in the historical assays which
should allow the current inferred resource to be reclassified in the indicated
and measured categories. This, in turn, should enable initial JORC compliant
reserves to be established for the project. The current reported JORC compliant
mineral resource is 41,517,000 tonnes @ 1.48 g/t Au for 1.98 million ounces of
gold at a 0.7 g/t Au cut off. This is estimated to an assumed economic mining
depth of 315m RL, approximately 120m below the current surface.
Total drilling to date is 14,518m from 115 holes since the programme started
(Table 1), including pre-collars for the metallurgical testwork sampling with
average drilling since the start of the programme of 241m per day. This is an
increase of 56 holes for 7,595m since the last work update announcement.
Drilling during the period focussed on Titan, south and north of Phoenix,
Bacchus South and reconnaissance drilling at Bonecrusher, which is located at
the northern end of the Bullabulling mineralised trend.
Results have been received for 82 RC holes and 6 Diamond drillholes out of a
total of 115 holes. Results from the remaining 27 holes are still pending, The
results from the drilling to date continues to increase our confidence in the
quality of the historic data and accuracy of our resource estimate. Only one
hole drilled to date has failed to intersect mineralisation and this was
predicted by the resource model (Table 2). The majority of holes are returning
intersections similar to those predicted by the resource model and about a
quarter are intersecting new zones of mineralisation outside the resource model
both below and along strike from known mineralisation.
New intersections not reported previously include:
* 7m at 1.44 g/t Au from 64m in BJ0041
* 18m at 4.37 g/t Au from 53m in BJ0057
* 18m at 1.10 g/t Au from 92m in BJ0058
* 5m at 1.45 g/t Au from 117m in BJ0058
* 5m at 2.10 g/t Au from 147m in BJ0063
* 12m at 1.07 g/t Au from 36m in BJ0067
* 12m at 1.08 g/t Au from 87m in BJ0071
* 11m at 1.15 g/t Au from 12m in BJ0074
* 6m at 1.73 g/t Au from 99m in BJ0077
* 12m at 1.94 g/t Au from 62m in BJ0079
* 4m at 3.30 g/t Au from 42m in BJ0084
* 5m at 8.20 g/t Au from 23m in BJ0085
* 7m at 1.64 g/t Au from 36m in BJ0085
* 16m at 1.09 g/t Au from 44m in BJ0091
* 6m at 1.41 g/t Au from 99m in BJ0092
* 10m at 1.16 g/t Au from 26m in BJ0093 and
* 6m at 1.41 g/t Au from 156m in BJ0095.
There are 303 intersections returned to date from 82 assayed RC holes, which
averages 4 intersections per hole relating to the multiple stacked lodes
defined by the structural mapping. These intersections have been compared to
the resource block model to assess the validity of the reported resource.
Approximately 22% of the reported intersections have returned gold
mineralisation outside the current resource model, which has been reported to
approximately 120m below surface and these will add to the current resource
base of the project.
Approximately 41% of the intersections returned similar grades or widths of
mineralisation to the resource model.
About 20% of the intersections have better grades or widths than predicted by
the resource model.
Only 17% of intersections returned widths not intersected or worse than
predicted by the model.
Resource Estimation
Snowden, the project geological consultants, continue to work on the new
resource and reserve estimate and are continuously reviewing drilling results
as they become available in relation to QAQC and drill spacing requirements to
upgrade the current resource to the Indicated and Measured categories. The
drilling QAQC Standard Operating Procedures (SOP's) have been reviewed
following a site visit and the QAQC twinning of historic Resolute drillholes
has been modified to infilling between holes rather than exact twinning of
historic holes. The QAQC part of the programme has consequently been redesigned
to infill down-dip of holes originally planned for twinning. A review of the
standards, blanks and duplicate samples to date has also been completed. While
a high number of the Quality Assurance Quality Control (QAQC) samples are
within the expected range of gold content, several batches of results have some
inconsistencies and these have been resubmitted.
A geostatistical review of the results to date suggest that a drill spacing of
at most 50 metres between sections along strike is required to classify any
resources as Indicated. Most of the area that is being targeted, between
Phoenix and Bacchus, is covered with a drill spacing of 50m or less. However,
the number of new intersections that lie outside the current resource model at
depth and to the east mean that additional drilling is required to infill these
areas to the required drill spacing. About 7km of additional drilling is now
planned to infill the new mineralisation with the aim of including these zones
in the new resource estimate to an Indicated Resource category.
Drilling Programme Increased
The total number of meters planned over the targeted 2.5km strike of the
Bullabulling trend has now increased to 24,140m over 175 drill holes. The new
JORC resource estimate is expected to be completed on track in Q2 2011.
Metallurgy Test Work
The recent review study included an assessment of historical metallurgy and
processing costs. The review has highlighted that processing costs are a
critical variable in the economics of the Project. Although recoveries
typically exceeded 90% and there does not appear to be any refractory gold
within the deposit, the economics of the project and mining of the ore zones
are sensitive to cut off grade. Also as the bulk of the resource upgrade has
come from transitional and fresh material at depth, and the majority of ore
processed historically came from oxide ore, a new metallurgical programme has
been designed to review the metallurgical characteristics of fresh ore in
detail with both physical and leaching properties closely examined. Gravity
gold recovery will also form part of the programme due to the anticipated
coarser gold in the plant feed, particularly the fresh ore.
Metallurgical core collected from the recent diamond drilling programme has
been logged, photographed and selected 20-25m intervals (300kg) from each
drillhole delivered to the Ammtec laboratory in Perth. The core has now been
reviewed and various samples selected for comminution (the process in which
solid materials are reduced in size, by crushing, grinding and other
techniques), recovery and variability test work. Results have been received
from the comminution metallurgical test work showing that a Bond Work Index of
6.9-9.5 with one sample at 12.6. In general the mineralised rock is competent
and should not have any issues when crushed.
The remaining core has been crushed and assayed and composite samples selected
with grades from 0.7 g/t - 1.5 g/t Au for recovery and metallurgical
variability test work. Lycopodium is currently reviewing the data and has
started modelling potential processing and plant capital costs, assuming a base
case plant capacity of 5.0 mtpa and an alternate plant capacity of 3.5 mtpa.
Preliminary crushing, mill and plant design work will also be carried out. This
information will then be used to define operating and capital costs for the
planned reserve estimation. Although at an early stage, the Bond Work Index is
softer than expected and this may lower the operational costs and therefore
lower the required economic cut-off grade.
New Prospecting Licences Acquired
The Joint Venture is also pleased to announce that new Prospecting Licences
have now been granted to the Joint Venture. The Joint Venture now controls
144km2 in the region. These areas cover most of the prospective areas along the
Bullabulling shear zone. The latest map of tenement will be available on the
Company's website.
