Drill cores taken by BRPM
since 1993 reveal the presence of continuous veins extending either horizontally or at depth, with tin grades ranging from 0.
exploration projects include gold and base metal mineralisation prospecting at Alouana, Tazekka and Tamlelt, and a pure gold project at Ourika.
Although there is the state body, BRPM
, its activities do not restrict those of other companies wishing to explore in Morocco.
SMI is another partnership of Omnium Nord Africain and BRPM.
It may well be that the success of ONA in mine development recently, as operating partner to BRPM, has been a factor in the government's often reported moves to restructure the BRPM.
Two BIMS rubbers used in this study are shown in Table 1, where BrPMS and PMS denote p-bromomethylstyrene and p-methylstyrene, respectively.
A high curative level in the BIMS-1 compound will result in a lower cure state because excess amounts of curatives will "graft and occupy some of the BrPMS groups in BIMS.
A more complex model also incorporated terms corresponding to the weight-% para-methylstyrene divided by the mole-% bromine (wt-% PMS/mole-% BrPMS ratio) and to the percentage of the para-methylstyrene sites that contain a bromine functionality (%PMS-Br).
