    Preparation of remedial action plan well advanced-Accept it did not happen!

    Independent Technical Reviews Support Recommencement
    of Operations at Cascavel


    Reviews by SRK and Mining Plus conclude that mining & recovery issues
    can be readily rectified.

    In summary, the key components of the plan to recommence operations at
    Cascavel include:
    • Increasing the amount of high-grade ore being delivered to the processing plant by revising the mine plan to open up more development in the higher grade southern portions of the mine.
    • Improving gold recoveries by enhancing the liberation of gold from the ore.
    •  Providing additional training to plant employees; and
    •  Increasing the amount of working capital available to the Company.

    Cascavel Gold Mine Independent Technical Reviews
    Overall, Mining Plus stated: "The issues observed at the Cascavel Mine are common start
    -up and
    commission(ing)
    problems, and we identified no "fundamental problems that should impede

    the mine from achieving success."

    Key issues and areas of improvements identified in the review process included:
    The key findings from the review of the Cascavel processing circuits were that gold recoveries were
    most likely to have been impacted due to insufficient liberation of the gold from the ore
    and from
    operator error during the first two months of operation of the plant.

    Modifications to the tertiary crusher (VSI) are required to overcome the poor performance
    of this crusher and the circuits inability to date to achieve the optimal particle size
    distribution for gold liberation.

    If further tuning of the VSI does not result in the achievement of the desired particle size distribution,
    then a small mill will be introduced to the circuit.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


    Well that's further reassurance & conformation that recent sampling results being received
    after particle size is reduced post finer crushing liberates more gold from utilising hammer mills.
    Its a pity for LTH-that this was not acted upon some 13 months ago when Reviews by SRK and
    Mining Plus conclude that mining & recovery issues
    can be readily rectified!!!

    Further that the KEY FINDINGS from the review
    Cascavel processing circuits were that gold recoveries were most likely to have been impacted
    due to insufficient liberation of the gold from the ore and from

    This historical review certainly packs & impact now post recent Hammer Mill Recovery
    averaging 45 grams gold per tonne from multiple mine locations !
    Well there was very little doubt in my mind that issues experienced with the gravity plant
    have now been identified will be confirmed as being overcome once the gravity plant becomes operational
    then sooner the better
    After reading the above I will now conclude there is NO DOUBT WATSO EVER -in my mind regarding
    the gravity plants ability to recover gold once gold recovery commences post the Hammer mills is installation
    & as previously stated be gold recovery should be in the 85 -88% range.
    GET THAT 25/30 TONNE PER HR HAMMER MILL INCORPORATED IN CIRUIT-& operating ASAP!!

    Further this is virtually conformation of what will be found when tails are sampled !!
    Its unfortunate for LTH-better late than never if there was a higher sentiment rating
    than buy I would use it.
    That's virtually 100% absolution conformation for me !!!!!!!!!!!
    Bloody Good One !!!!!!
    GLTAH-always pay's to reread & analyse old announcements .
    imo Additionally when this resonates unlikely to be just mine .
