    In ref. to my prior post,probably best to start a new thread.

    This is the best summary of Madagascar's geomorpholy:

    www.smedg.org.au/Premoli.htm
    and quoting from this

    "The Graphite system:

    Rocks assigned to this system form the greatest part of Madagascar's Basement - and they are also
    the most consistently mineralised in gold. The system is characterised by the presence of
    graphite in greater or lesser abundance. The intensity of metamorphism varies according to
    location; the different regional groups are still defined by their metamorphic grade rather than
    their stratigraphic relationship."

    Bass's holdings sit in the drainage area from Madagascar's known gold area

    7.2.6. AMBOSITRA-ANTANANARIVO GOLD DISTRICT


    Location and history

    The Ambositra-Antananarivo gold district is particularly developed in the province of Antsirabe
    and officially produced 1,489 kg (48,000 oz.) between 1901 and 1921. The largest part of this
    production came from the region south of the Onive River (sketch 7/8). Some deposits occurred
    around Ambatolampy and in the Faratsilho sector.

    Gold production was particularly important from 1890, when the exploitation was carried out by
    administrative corve‚s. Around 1900 these corve‚s employed more than 2,000 workers in the
    Sarobaratra River alone. The inevitable exhaustion of the alluvial resources took place
    immediately afterwards and was a powerful incentive to the first exploitation of primary gold,
    particularly where their contacts with the overlying laterites formed zones of strong enrichment.

    This gave the district a new lease of life with a high production between 1904 and 1911. At that
    time numerous exploitation of graphite were developed and attracted labour away from the less
    lucrative gold workings. Production has been totally artisanal ever since.

    It would be futile to list all the deposits that occur in the Ambositra-Antananarivo goldfield.
    In any case records are very scarce, and they are mainly known by traces on ancient workings
    (Besairie, 1966, p 276).

    The heart of this goldfield can easily be reached by 100-180 km of excellent surfaced road from
    Tananarive (sketch 7/15); most individual deposits can be reached only by 4WD vehicles,
    particularly during the rainy season. The town of Antsirabe offers very good and pleasant
    accommodation."


    ........I leave the bagger estimation to the DOC if gold were part of the equation
