Rock Chip Sampling at Laing’s Lode Successfully Identifies Targets due to results from a program of 262 rock chips taken from the 100% owned Laing’s Lode EL 6857 located approximately 30 km north of Broken Hill have returned high lead, zinc and silver results. The aim of the survey was to confirm the anomalous zinc and lead results reported by CRAE over the LL Prospect (formerly referred to as the Laing’s Lode Prospect) and also identify other targets in the tenement. See location figure 1 below.
Exploration work included reconnaissance sampling of quartz-gahnite and related rock type exposures over the Laing’s Lode EL. Highly anomalous geochemistry results including previously unknown elevated silver and lead concentrations were returned (See Figure 2) from this program. Examples include sample 2731: 14.1 g/t Ag; 2.89% Pb and 1.94% Zn, and sample 2732: 19 g/t Ag; 2.58% Pb and 0.98% Zn.
Quartz-gahnite is an unusual rock type that is intimately associated with the giant Broken Hill silver/ lead/ zinc (Ag, Pb, Zn) deposit and is a well-known proximity indicator to potential Broken Hill style massive sulfide mineralization in the district.

At the LL Prospect, 225 samples were taken on a detailed grid of an area of approximately 500 metres X 400 metres. Results from the grid sampling were all highly base metal anomalous, with 8 samples, all of heavily iron stained quartz-gahnite or similar lode style rock exposures, assayed in excess of 4.0% zinc (See Figure 2). The main outcrop of iron-stained quartz-gahnite covers approximately 300 metres x 100 metres. To the NNW of this outcrop, an Induced Polarisation (IP) (undertaken by CRAE) chargeability anomaly extends the potential target zone below surface at shallow depths for a further 200 metres along strike. The recently completed sampling by Carpentaria and analysis of historical IP data indicates the 3 previous open hole percussion holes drilled at this prospect were poorly located and did not adequately test its economic potential. Carpentaria will RC drill test this Prospect.

On a regional scale 32 samples returned highly anomalous geochemistry results including previously unknown elevated silver and lead concentrations. (See Figure 2). Examples include sample 2731: 14.1 g/t Ag; 2.89% Pb and 1.94% Zn, and sample 2732: 19 g/t Ag; 2.58% Pb and, 0.98% Zn. Additional sampling and mapping is required to define other targets.
