Drilling has helped to define the Pepper 4 kimberlite on Vaaldiam Resources‘ (VAA-V) Pimenta Bueno property, about 70 km east-southeast of the town of Pimenta Bueno, in Rondnia state, western Brazil.
Five of seven holes intersected kimberlite. Of the five holes, three were vertical and two were angled at 45. The holes cut from 75-164 metres of tuffisitic kimberlite breccia. All ended in kimberlite. In total 583.7 metres of kimberlite core, weighing an estimated 2.7 tonnes, was sampled.
The Pepper 4 pipe has a minimum surface area of seven hectares and is covered by about 30 metres of sandstone. The pipe is composed of at least two types of diatreme facies kimberlite. The holes defined the southern and eastern margins of the pipe; the northern and western margins remain open.
The 1,760-sq.-km property hosts at least 33 kimberlite pipes, 15 of which are known to be diamond-bearing.
The seven Pepper kimberlite pipes lie within a 2.5-km radius. An ongoing drill program is attempting to delineate each pipe with five to six drill holes and three to five tonnes of kimberlite will be collected from each pipe for microdiamond analysis.
The first hole in the Pepper 13 pipe, 100 metres west-northwest of Pepper 4, has cut kimberlite at 23.5 metres down hole and is still in kimberlite at 138 metres depth.
The company continues to explore for additional pipes on the property.
In addition, Vaaldiam is performing due diligence on the 70-sq-km Duas Barras alluvial diamond property, 150 kilometres north of the town of Diamantina, in Minas Gerais state. The company has an option to earn a 70%-interest in the property from Brazilian-based Minerao Marly. A mobile diamond recovery plant capable of processing 10 cubic metres of gravel per hour will test samples from the site.
