This recent drilling has defined a large zone of sulphide alteration that extends the system over 2km west of previous known limits, and to a depth of at least 800 metres.
The initial three drill hole program on a previously unidentified anomaly has confirmed the validity of the deep penetrating IP technique with each drill hole intersecting extensive disseminated pyrite alteration of sufficient intensity and distribution to explain the chargeability response.
The alteration and chargeability anomalies are open to the north, west and south, and open at depth, presenting significant potential for future mineralisation discovery. The success of the IP technique provides confidence in further defining the system with follow-up IP in conjunction with more detailed analytical studies on the drill core to help vector towards the source of mineralisation.
Anomalous copper, gold and pathfinder element results have confirmed that the large alteration zone encountered in drilling is an extension of the mineralising system that contains numerous copper, gold and silver workings in addition to the known Resources that form part of the Mt Carrington development project.
White Rock Mineral chief operating officer Matthew Gill said: "The White Rock technical team is encouraged that such a large alteration system has been defined in addition to the known gold-silver Resources at Mt Carrington. The new extension presents a significant area of prospectivity with no previous drilling having been completed beyond the three recent drill holes. Such exploration potential now provides significant upside to any future development of the Mt Carrington project and reinforces our motivation to ensure that the value of the project is unlocked."
White Rock plans to evaluate the drill core using techniques developed in recent years that will assist with establishing the potential of the hydrothermal system and provide vectors to help target mineralisation. These techniques include sulphur isotopes, white mica crystallinity and chlorite chemistry, each of which will aid in further understanding whether a copper-gold porphyry system is driving the alteration. In addition, this information will also identify further epithermal gold targets at shallow levels that could augment the existing gold-silver resource development plans now the focus of feasibility studies.
White Rock is also in discussions to define complimentary Masters and PhD projects with leading Australian Universities that will assist in ensuring the latest techniques are executed in advancing the exploration of the whole mineralised system at Mt Carrington.
White Rock is pleased to acknowledge the NSW Government’s co-funding drilling initiative program, from which the Company will be reimbursed approximately $140,000 of direct drilling costs.
