GOLD TRENDS IDENTIFIED AT CONTO’S CARDINIA BORE PROJECT
Highlights
-
Soil sampling identifies gold anomalies up to 17ppb
-
Silver anomalies also identified
-
Coherent gold anomalous zones with coincident multi-element trends returned in MMI soil geochemistry
-
The main anomalous areas coincide with the interpreted intersection between NW and NE trending structures

Conto Resources Limited (ASX: CNO ) ( Conto or The Company ) is pleased to report that it has received all results for the Mobile Metal Ion[1] (MMI) soil sampling program completed at its Cardinia Bore Project, east of Leonora. The returned gold results, which form several coherent anomalies above geological structures, add significantly to the understanding and prospectivity of the Cardinia Bore area ( Figure1 ).
Gold anomalism is up to 37 times background with peak raw values of 17 ppb occurring in soils adjacent to a sheared contact between mafic and ultramafic volcanics. The gold is coincident with several pathfinder elements, including silver, cadmium and copper. It also lies above the interpreted intersection of north northeast-trending structures with the main north-northwest trending faults.
Technical information
The known resources in the vicinity of the Cardinia Bore Project are contained within a sub-horizontal supergene zone lying within 50m of the surface. To date no significant primary mineralisation has been defined. The sharpness and high contrast inherent in the MMI technique, which specifically target signals sourced from primary mineralisation, make it favourable as a targeting tool to facilitate discovery of mineralization in the early stages of exploration programs.
The MMI survey involved the collection of 328 soil samples (excluding standards and duplicates) on a 200x200m grid across the entire Cardinia Bore Project area. SGS Laboratories in Perth received the samples, and analysed for a multi commodity exploration package comprising of 45 elements. The MMI package represents the preferred digest package for geochemical exploration.
Results
MMI soil geochemistry has identified several large and coherent gold anomalies with peak values of up to 37 time background (max. 17 ppb Au)[2] (Refer to Appendix A). The gold anomalies coexist with laterally persistent multi-element corridors defined by anomalous concentrations in several pathfinder elements, including silver, cadmium, and copper. The corridors are developed generally parallel to the regional foliation and correspond with interpreted fault zones. The faults parallel the NNW-trending Keith-Kilkenny lineament, which lies just west of the area. The multi-element corridors and anomalous gold also lie above crosscutting, NNE-trending splays.
The gold anomalies also occur along strike from historical mines and include areas where no previous exploration drilling has taken place.
The geometry of the geology and geochemistry supports a riedel shear model.
The Company is planning infill geochemical sampling to test these targets.
Competent Person Statements
Technical information in this report has been prepared under the supervision of Mr Jonathan King, a member of the Australian Institute of Geoscientist (AIG). Mr King has sufficient experience which is relevant to the styles of mineralisation under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves” (the JORC Code). Mr King consents to the inclusion in this report of the Information, in the form and context in which it appears.
1 MMI geochemistry is a super sensitive technique that analyses extremely low levels of elements that adhere as metal ions to the soil particles. These ions having travelled vertically through the regolith cover from metal bodies below, accurately report the position of these bodies at surface.
2 Geochemical background is defined as the normal abundance of an element in the explored hinterland. Geochemical anomalies exist when returned results in the target element appreciably exceed the normal reporting or ‘background’ level of the enclosing rocks: the higher the ratio the more significant the degree of enrichment.

About Conto
Conto Resources Limited is an Australian-based exploration company established to cost effectively explore its Lone Wolf Projects and Cardinia Bore areas and actively seek acquisition opportunities.
The Lone Wolf Project is located approximately 15km northeast of Leonora within the North Eastern Goldfields region of Western Australia. The project consists of two prospecting licence applications, covering a total area of approximately 3.2km[2] . The limited wide spaced historical drilling has outlined a continuous mineralised strike of 830m.
The Cardinia Bore Project is located approximately 28 km ENE of Leonora and consists of 9 tenements covering 1,309 hectares.
