Rokmaster Resources Corp. has satisfied the initial terms of its option agreement with Patrick James Burns to acquire a 100% interest in the Cristal Project in northern Chile.

The transaction secures the company's entry into the property, which comprises approximately nine square kilometres of contiguous exploitation mineral concessions. The ground sits along the West Fissure, north of the Collahuasi/Ujina porphyry copper district. To complete the initial requirements, Rokmaster received acceptance from the TSX Venture Exchange, issued 7,000,000 common shares to the optionor, and paid US$70,000 in cash.

“In addition to our existing Canadian porphyry projects, we are very pleased to have now added a compelling porphyry copper target in Chile. The region hosts 49 known giant porphyry copper deposits within 25 discrete clusters including Escondida, the worlds largest copper mine. Rokmaster has now completed the initial terms under the Cristal option agreement. This represents an important milestone for Rokmaster and we look forward to initiating further geophysical surveys at Cristal to refine the historical undrilled targets discovered during previous work by BHP and others, which our initial diamond drill program will test.”

— John Mirko, CEO & Director

With the initial acquisition steps finished, Rokmaster plans to initiate further geophysical surveys at the property to refine historical undrilled targets identified during previous work by BHP and others. These refined targets will then be tested by the company's upcoming initial diamond drill program.

“The geophysical signature at Cristal is compelling and significant in scale. Magnetic data define a strong, circular, doughnut-shaped anomaly approximately three kilometres in diameter and centred on the Property. The anomaly comprises a weak central magnetic high surrounded by a magnetic low-a pattern that may reflect alteration zoning associated with a buried porphyry copper system. The scale and geometry of this magnetic response, together with supporting electromagnetic and regional structural evidence, make Cristal a high-priority exploration target.”

— Dr. Thomas A. Henricksen, P.Geo., author of the 2018 NI 43-101 Cristal Project Technical Report

The upcoming geophysical work and subsequent diamond drilling will focus on evaluating the structural and magnetic anomalies outlined in historical technical assessments.
