Critical has received the green light to start drilling at the Sunnyside prospect within its Halls Peak project in New South Wales.

The final approval paves the way for the company to carry out 1,700m of diamond drilling to test geophysical anomalies to a maximum depth of 700m.

This is aimed at expanding the overall potential of the Halls Peak system and demonstrate continuity of mineralisation between the Gibsons and Sunnyside prospects.

Critical Resources (ASX:CRR) expects Sunnyside drilling to begin once the remaining five holes at the Gibsons prospect are completed.

Recent drilling at Gibsons has intersected copper and deep disseminated sulphide mineralisation

“Being able to drill the previously untested geophysical anomalies seen at Sunnyside represents a major step in our exploration program at Halls Peak,” managing director Alex Biggs said.

“The Sunnyside prospect is approximately 1.5km from the Gibsons prospect so represents a clear expansion of the resource potential that exists at Halls Peak.”

Sunnyside up

The drill targets at Sunnyside were developed through reinterpretation and analysis of data collected in a 2012 Versatile Time Domain Electromagnetic survey.

Additionally, all holes will be subject to downhole electromagnetic surveying that will aid the company in refining further targets for the next stage of drilling.

Critical believes this staged approach to exploration will enable more accurate, lower risk, target development and more efficient placement of future holes and further exploration of the down dip and down plunge extensions to known mineralisation.

Halls Peak project

The Halls Peak project is located about 45km southeast of Armidale in the New England Fold Belt, an area that is known for its mineral endowment and production.

Massive sulphide deposits were first discovered in 1896 with near-surface mining extracting high-grade zinc, lead, copper and silver.

Halls Peak itself comprises historical mines and prospects such as Gibsons, Sunnyside, Firefly, Faints, Khans Creek, Keys and Mickey Mouse.
