Macarthur Intersects Thick Magnetite Zones in Stage 2 Drilling

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 6, 2006) - Macarthur Minerals Limited (TSX VENTURE:MMS) (the "Company") wishes to advise that it has just received the primary results from the Davis Tube Analysis derived from Stage 2 drilling.

From the Davis Tube Test primary results received, seven holes in the Stage 2 drilling have intersected thick down hole widths of magnetite minerlisation.

The average intersection of the drill holes is 92 meters
BIF equals Banded Iron Formation


The final XRF (refer to definition below) assays of the magnetic concentrate often lags 7 to 10 days in arrears; the final assays will be reported as they are presented to the Company. To-date the Company has received only one assay file, which includes a 35 meter interval from LGRC_011 (see Table 3). Further results from the intersection are still pending.

XRF is the method used to measure the elemental composition of materials.
