    ANNOUNCEMENT BY NEW TALISMAN GOLD MINES LIMITED (NTL, NTLOA or NTLO)
    FOR IMMEDIATE RELEASE
    
    - FIRST GOLD RECOVERED FROM METALLURGICAL SAMPLES
    - HIGH GRADE ORE ALLOWS FOR NON CHEMICAL RECOVERY METHODS
    
    New Talisman Gold Mines Limited ("NTL"), today announces the first recovery
    of gold from its Talisman gold mine as part of its metallurgical sampling as
    a precursor to bulk sampling ramp up and test work. This was recovered
    utilising state of the art non chemical extraction methods.
    Talisman is an important gold resource for New Zealand and was in the past a
    prolific gold producer and employer having produced 1 m oz of gold
    historically, in a gold region which has produced over 8m oz of gold.
    GOLD RECOVERED FROM METALLURGICAL SAMPLING
    Metallurgical test work investigated a suitable floatation and gravity
    recovery method of extracting gold from ore samples.  The company tested 146
    kg of very finely ground ore and has produced approximately 3 ounces of gold
    and silver.  Further concentrates will be used for more test work to evaluate
    the most effective recovery rates.
    Sample Collection
    Hand selected samples were collected from the Talisman stockpile in bags of
    approximately 8kg each. Samples were classified into rock types and an
    example of each type retained for identification purposes. Samples were then
    processed at the SGS Waihi laboratory being crushed and pulverised before
    passing through a 50 micron screen (approximately the same grain size as
    cement).  The pulverised product was then thoroughly mixed and a
    representative sample taken for assay purposes.
    Lower grade samples were discarded as the equipment is not sensitive enough
    to record micro gram recovery levels. The assay results of the samples
    selected for processing are tabulated below and a photographic record of
    examples of those samples is shown in the table - see pdf attached.
    
    Primary Concentrating
    
    This testwork relied heavily on wet gravity separation to remove the clay and
    other light minerals from the heavier electrum and sulphide minerals. It was
    found to be important to pass as clean a concentrate as possible through the
    final concentrator as the equipment relies on recirculating water and excess
    clay was kept in suspension causing cloudy water to be passed back through
    the separator bowl.
    In order to float out the clay approximately 2.5kg at a time of the sample
    was added to a bucket along with 3 litres of water and a small amount of
    surfactant to break surface tension and prevent fine gold particles being
    washed away. The mixture was stirred thoroughly to move the clay into
    suspension and then allowed to settle for a minute. Approximately 2/3rd of
    the liquid was then decanted and the process repeated until rapid settling
    was attained. It was found that, on average and dependant on the grade of the
    sample, a 7kg sample could be concentrated to approximately 160g of material
    which was then passed through the final concentrator.
    
    Matthew Hill, Executive Director, said "whilst this is a small amount of
    gold, in the larger scheme of things it is key to demonstrating our fuller
    understanding of the effectiveness of our extraction method options.  Without
    unnecessary expenditure and use of chemicals, we have identified a number of
    manufacturers to scale up the treatment options allowing for concentration
    and extraction, prior to any toll treatment driving early revenues to the
    company."
    ABOVE: THE GOLD LAB UTILISING GRAVITY AND FLOTATION - resulting gold
    recovered
    "These are the first ounces recovered from the Talisman ore since New
    Talisman owned the permit and show the huge strides the company has made its
    final steps toward bulk sampling for which final approvals are underway.  We
    have found nothing but support from shareholders and the wider community."
    Following initial test work we expect to be able to recover up to 30 oz gold
    per month using existing samples, while initiating precursor work toward bulk
    sampling.
