GREENLIGHT RESOURCES INC. (TSXV.GR), announces that the results of its 28 hole, 2,592 meter diamond drill program on its Brazil Lake Lithium project.
The Brazil Lake property, which has excellent access and infrastructure, is located near the deep water port of Yarmouth Nova Scotia.
Diamond drilling by the Company in the fall of 2010 was focused primarily on structural drilling to define the extensions of the two Lithium-bearing pegmatite dikes outlined in previous exploration efforts. The two spodumene-bearing pegmatite bodies are 275 to 300 meters in length and 300 meters apart, trending approximately 050°, dipping 55° to 75° SE and plunging to the south at approximately 50°.
The 2010 drill program shows the North Dike to have a maximum true thickness of 17 meters averaging about 8.5 meters. The dike is approximately 300 meters in length and the Lithium-bearing portion of it is approximately 160 meters in length and has been followed down dip for a distance of 175m (115 meters vertical depth). It remains open at depth. While drill holes from the current program were located primarily on the down-dip extensions of the pegmatite, the lithium content of the North Dike ranged from 0.25% Li2O to a high of 2.15% Li2O with an average of 1.08% Li2O.
Based on the results of the 2010 drill program, the South dike has a strike length of 120 meters and an average width of 5.7 meters. It has been traced down dip for a distance of 80 meters. Drill hole intercepts from the current program ranged from 0.02% Li2O to a high of 2.23% Li2O returned an average grade of 0.69% Li2O. Lithium grades here are also open down-plunge. Channel samples were also taken from seven drill holes drilled to approximately 20 meters depth along the strike of the south dike. Drill hole intercepts from these holes ranged from 0.03% Li2O to a high of 2.30% Li2O returned an average grade of 1.39% Li2O.
Significant intersections of Rubidium (Rb) were also encountered in some holes. Examples of the grades included Hole BZ-10-01 which returned values up to 0.17% Rb over 5.24 meters, Hole BZ-10-03 which returned values up to 0.11% Rb over 10.94 meters, Hole BZ-10-12 which returned values up to 0.11% Rb over 8.48 meters and Hole BZ-10-20 which returned values up to 0.14% Rb over 27.40 meters.
Future drill programs will include infill drilling for increased resource definition and identifying high grade shoots within the dikes. The drilling and other data on the property has been turned over to an independent geological consulting firm, which will produce a 43-101 compliant resource calculation.
Continuing Exploration Programs
Field exploration commenced in January 2011 is being carried out on areas of pegmatite float approximately one kilometer south of the North Dike known as the Church Road area. The Church Road area is marked by the presence of both large boulders of spodumene pegmatite and of small fragments of spodumene crystals in the overburden. A nominal 100 by 100 meter grid of backhoe pits has been dug up-ice from the northernmost point of spodumene-bearing boulders. The pits are sampled at 1meter intervals and about 10 kilograms of till from each interval is screened and washed and the spodumene crystals are collected and counted. As the source area for the spodumene is approached the number of spodumene-bearing fragments should increase toward the base of the till column. The train has been traced by pitting for over a kilometer and now significant concentrations of spodumene are being seen in the basal till. Further pitting will be carried out to "hone -in" on the source dike. It is felt that a new discovery is imminent there.
The property, which is mostly overburden covered, has good potential for finding more spodumene bearing pegmatite bodies.
Silchlor Cyclic Vacuum Chlorination Process
The Company also confirms that it is proceeding with the testing and evaluation of its patented Silchlor Cyclic Vacuum Chlorination Process announced October 28, 2010. Dr. Ian Flint of Halifax, Nova Scotia has been retained to manage the assembly of a small scale reactor as well as supervise its testing and evaluation. Assayed samples from the Brazil Lake drilling program discussed above will be used in order to ascertain the commerciality of the Silchlor process on extracting Lithium from the Brazil Lake Spodumene.
The objectives of the Company's bench testing of the Silchlor Cyclic Vacuum Process include:
- Demonstrate similar or lower cost profiles as the solar brine process used to extract Lithium from salt pans in South America and Nevada.
- Minimize waste product.
- Reduction in impurities in the initial Lithium Chloride product which could allow for less complicated procedures to produce high purity products with increased values.
- Recovery of additional marketable products in the Spodumene, in particular Rubidium as well as aluminum chloride and silica tetrachloride.
Current Lithium prices area approximately $6,500 per tonne and Rubidium is approximately $11,000 per kilogram.
Rare Earth Element Project - Porcupine Upper Miramichi
On October 15th 2010, the Company announced the signing of a letter of intent to earn up to a 100% undivided interest in the Porcupine-Upper Miramichi Rare Earth Property in New Brunswick. The primary target is the various rare earth elements (REE) that were discovered in soil samples on the property in 2007. Soil assays for REE's include Samarium (Sm), with reported with grades of up to 218 ppm (g/t) and Dysprosium (Dy) with grades of up to 98.6 ppm (g/t), Neodymium (Nd) with grades of up to 1190 ppm (g/t), Ytterbium (Yb) with grades of up to 31.3 ppm (g/t) and Yttrium (Y) with grades of up to 472 ppm (g/t). Reported assays for Heavy REE's include Terbium (Tb) with grades up to 20.3 ppm (g/t) and Ytterbium (Yb) with grades up to 31.3 ppm (g/t) while reported light rare earth metals include Cerium (Ce) with grades up to 459 ppm (g/t) and Lanthanum (La) with grades up to 1,300 ppm (g/t).
