molybdenum in the pilbara 470ppm, 100m

GDA has Molybdenum (Mo) in its Pilbara tenements and I've have been searching for info on (Mo)to try and get a handle on what prospects GDA's Mo has. Found this article on Mo from the Mining Daily, 22 oct 09...

"Ivanhoe Australia has discovered
high grade molybdenum
and rhenium mineralisation
close to its current Merlin
deposit in Queensland.
Christened the Little Wizard
deposit, Ivanhoe expects
the 15,000 tonne inferred
resource to provide potential
early cash flow of up to $100
million through selling the
material as Direct Shipping
Ore (DSO).
This cash flow represents
a substantial portion of
Merlin’s development capital
expenditure.
The 15,000 tonnes is graded
at 13% molybdenum, 160
grams per tonne of rhenium,
1.7% copper and 0.8 grams
per tonne of gold.
According to reports, the
Little Wizard zone lies 90
metres below the surface and
is 55 metres west of the current
proposed Merlin deposit.
While Little Wizard has
been delineated as a separate
mineralised system, Ivanhoe
geologists believe that further
surveys may define the potential
connection between the
Little Wizard Zone and its
main Merlin Deposit."

We know GDA has molybdenum (Mo) south of Moly Mines, spinifex project, with past drilling intersecting good depths from just two holes ( one hole was only drilled to find a water source but hit good grades of Mo. The grade from the two drill holes in GDA's tenement is not as high as Ivanhoe's. It will be interesting to see what grade and depths exist when they get into the main body.

The questions are....
If 15,000 tonnes that Ivanhoe has is worth $100m from a grade of 16% DSO, how much has GDA got and at what grade ?

"A significant amount of historic work has been performed on this tenement, with copper–molybdenum mineralisation being discovered at the Gobbo’s prospect in the 1960’s. Significant historic geochemical assay results have been extracted from open file reports on the tenement. During 1973, Australian Anglo American Limited (AAAL) undertook an extensive rock chip sampling program over the outcropping copper gossans along the northern edge of the Gobbo’s granodiorite intrusive (open file report A5199). This survey delineated 41 rock chip samples over 0.1% copper.
Subsequent explorers reviewed the 1960’s and 1970’s exploration results and in 1980 a drill program by AMAX
tested the best outcropping Cu-Mo mineralisation exposure. Only two holes were drilled - one shallow percussion drill hole and one deep diamond drill hole - both hitting Molybdenum mineralisation.
The shallow 30m-deep vertical percussion hole GDH1 was drilled to obtain a water supply for the deeper diamond hole collared 60m to the south east. The percussion hole ended in 470ppm Molybdenum mineralisation and averaged 13m @ 204ppm Mo from 17m depth. The 315m deep diamond hole GDDH2
was drilled towards the south at -50 ⁰ dip. This hole was located 200m due north of a quartz-porphyry / metabasalt contact. The diamond hole intersected quartz veins with visible Molybdenum mineralisation in the top half of the hole.
Open file report A9462 suggests the porphyry may be a thin shell only and the main granodiorite body may be less than 50m away. Hole GDDH002 was assayed in 3m sections and when averaged, measured 66m @ 219ppm Mo from 75m downhole depth. This hole intersected 7 zones of +300ppm Mo mineralisation from 18m to 135m downhole depth, with the drill hole trace and Mo assays of economic interest.
The copper anomalism demonstrates that the target is significant in size and only partially drill tested on the
eastern margin.
This project has the potential to be similar in mineralisation style to Porphyry / Granodiorite Cu-Mo deposits such as Spinifex Ridge, 80km to the north.
Field work on this tenement will continue in the 2010 field season, and the primary focus will be to assess potential for a Mo-Cu resource. As the existing mineralisation is located from surface to 100m vertical depth, it may be amenable to open cut methods should additional mineralisation be discovered with further drilling.
The steel additive Molybdenum is sought after by the steel mills, and this commodity fits well with the company’s multi-element exploration strategy to identify economic resources of commodities in demand.
