(MENAFN- ProactiveInvestors - N.America) Samples from Noram Ventures Inc''s (CVE:NRM) Clayton Valley programmes are to be re-assayed to establish a low cost processing method, the firm said.
The work will be done at ALS Chemex in Nevada to provide additional data on the viability of large-scale leaching of lithium from the mineralised claystones, it said.
The idea is lithium could then be produced directly with a low cost and environmentally sensitive approach, reducing the need for roasting or other costly, complex processes.
Noram''s President, Mark Ireton, told investors: "We expect the results of the leach re-assaying will add significantly to our knowledge base on the most effective method of recovery and help develop a conceptual model for further development of the companies'' lithium claystone assets."
Once the ongoing surface sampling phases have been completed, shallow core drilling is recommended to enhance the understanding of the geology, lithium grades and thicknesses.
Drill collar locations and the numbers of holes is yet to be decided.
Earlier this week, the group said it had broadened surface sampling work at the Clayton Valley, Nevada acreage to include the newly acquired Zeus and Spartan lithium brine/clay claim groups.
Initial samples at Zeus returned lithium in a range of 196 parts per million (ppm) to a high of 760ppm with a 530ppm average.
The Zeus and Spartan calms are part of the recently acquired South Block Extension that consists of 550 claims in three contiguous groups (Zeus, Hades and Spartan) covering around 10,740 acres.
