All Grade Mining Reports Positive Sample Results for its Plateada Copper Project


By All Grade Mining

Samples Reveal Higher than Expected Traces of Gold, Silver and Copper Sulfide Concentrate

HASBROUCK HEIGHTS, N.J. / ACCESSWIRE / April 4, 2014 / All Grade Mining (OTCQB: HYII), a development-stage company focused on the extraction of copper, today reported that recent samples taken from its Plateada copper property show higher than expected trace amounts of gold and silver as well as high concentration copper sulfide.

According to lab results for base metals and solubility based on samples taken on the Plateada property, copper sulfide exists at Plateada in the range up to 7.75% grade. The standard commercializable grade for copper sulfide is generally 0.5% or greater meaning that when concentrated CU content per ton of concentrate will be as high as 40%. The samples were collected by Ambiental Chile, SA, an engineering firm hired by All Grade Mining’s primary consultant, Foreign Commerce Consultative Services, Inc.

Copper oxide samples from the property reportedly range between .021% and 4.2%, which management states is commercial grade and could easily be sold to ENAMI or other entities once produced. Additionally, samples indicate that the property’s gold would yield between 0.5 and 2.1 grams per ton and silver would yield between 286 and 550 grams per ton.

Based on these results, All Grade Mining projects that its Plateada Copper Sulfide Project will produce 45,000 tons of total mineral concentrate during its first year of operation, which would generate $3.87 million in revenue.

In addition to taking mineral samples, Ambiental Chile, SA has also completed the assessment and expansion study on Plateada and All Grade Mining expects to receive these full results in the near future, including tonnage and reserve estimate of the property’s mineralization body, confirming the overall value of the mine and its life expectancy. The Company also reports that the first level tunnel structure in the mine was imploded and the expansion plan for the lower level is complete.

“All Grade Mining is very excited to report recent sample results indicating that our Plateada project will produce more revenue per ton than initially projected due to a greater presence of trace gold and silver than expected. With these new findings, company has now increased the profit margins on our Plateada project and we look forward to announcing the results of our final assessment and expansion study on the property in the near future,” commented Gary Kouletas, CEO of All Grade Mining.
