To See Table Results Guyanor Ressources and Golden Star Resources announced today the results from the bulk sampling program undertaken by Guyanor and its joint venture partner Rio Tinto Mining and Exploration Limited on the Dachine Diamond project in French Guiana. The program was designed to sample a large volume of material from various zones of the Dachine ultramafic body to yield a parcel of diamonds in order to confirm the presence of gem quality stones. Using a cut-off size of 1 mm, grades varied from 0.06 to 10.48 carats per hundred tonnes. The largest stones were found in the 1.7 to 2.36 mm size range, with an average weight of 0.066 carats. However, the majority of the stones occurs in the ranges of 1 to 1.18 mm and 1.18 to 1.70 mm.
Stones are translucid to transparent, but often masked by large quantities of inclusions.
The dominant shapes are irregular, with small quantities of cubic and octahedral stones. Stones are often intensely reabsorbed. These results are considered disappointing and no further project work is planned at this time. Rio Tinto has advised Guyanor Ressources that, given the results obtained, it intends to withdraw from the project and terminate their joint venture. Guyanor Ressources will probably continue evaluating the remaining targets in the region, notably Vitoria and Palofini, where diamonds were found early this year.
