-
Survey results are highly encouraging and confirm significant base and precious metal anomalism
-
Potential mineralisation styles include;
-
Mississippi Valley Type (MVT( base metal)
-
Volcanic associated (VHMS) base metals mineralisation

Epithermal gold –silver mineralisation
-
Drill targets currently being identified and drilling planned to commence by the end of Q1, 2011
Perth based exploration company Laconia Resources Limited (ASX: LCR) is pleased to announce that a recently completed geochemical survey at the Company’s Barramine Gold and Base Metal Project has confirmed the potential for the project to host significant base metal and gold mineralisation.
The Company advises that it completed a systematic geochemical survey at the Barramine Project in September, which was designed to follow up previously defined airborne geophysical anomalies (EM anomalies) at the project area. The results have proved highly encouraging and have confirmed the potential for the project to host base metal and gold mineralisation.
The Company is currently in the process of identifying drill targets (incorporating geophysical, geochemical and geological field mapping) and aims to commence drilling at the project by the end of Q1, 2011.
The Barramine project is located in the East Pilbara region, 250km east of Port Hedland.
The geochemical survey results are preliminary and follow up sampling has now been initiated. The work to date confirms the presence of EM anomalies and has also identified multiple mineralisation styles. Potential mineralisation styles identified include:
-
Mississippi Valley Type (MVT) base metal (Pb-Zn) mineralisation associated with the limestone and chert breccias.
-
Volcanic associated style (VHMS) base metal (Cu-Pb-Zn) and precious metal (Au-Ag) mineralisation associated with the underlying mafic to intermediate volcanics and volcaniclastics.
-
Structurally controlled and replacement style hydrothermal copper-gold mineralisation within limestone and chert breccia units, similar to the Barramine and Camel Hump prospects.
-
Epithermal gold-silver mineralisation.
Survey details
Regional MAGSTREAM and fine fraction stream sediment surveys were implemented to assess the potential for the various styles of mineralisation. Grid MAGLAG and -40# soil sampling geochemical surveys were implemented over previously defined airborne EM anomalies.
A total of 200 MAGSTREAM samples, 200 fine fraction stream sediment samples, 346 grid MAGLAG and 229 grid -40# soil samples have been collected and analysed for a multi-element suite, by Actlabs Laboratories in Perth.
Preliminary Survey results
MAGSTREAM data has confirmed the presence of anomalous Zn (>500 ppm, up to 1140 ppm) and Pb (>45 ppm, up to 194 ppm) values in the northwestern and southeastern portions of the overlying Carawine Limestone and associated Pinjina Chert (breccia). The base metal anomalies are supported by anomalous Ag, As, Mo, Hg, Ba and Sr values and may indicate the presence of MVT-style mineralisation associated with the limestone units.
The underlying Jeerinah intermediate volcanics and volcaniclastics include volcanic agglomerates, indicating the presence of a volcanic centre with strong potential for associated base and precious metal mineralisation. The intermediate volcanics are associated with high background to anomalous Zn (>200 ppm, up to 1300 ppm), Cu (>100 ppm, up to 261 ppm), Au (>2.5 ppb) and As (> 20 ppm) values in the MAGSTREAM data.

Grid MAGLAG and soil samples are still being evaluated over areas selected on the basis of anomalous geophysics. The northernmost grid (covering a 1200m x 1800m area) returned encouraging spot high Au values up to 267 ppb Au, occurring within two 1000 metre long, north-northwesterly trending, anomalous (>2.5 ppb Au) zones along a structural contact. The anomalous Au trends are supported by anomalous Cu, Sb, Tl, Hg, Bi,Te and As values that are typically associated with epithermal-style gold and silver mineralisation. The grid was designed to cover a strong airborne EM anomaly that would appear to be supported by the anomalous geochemistry.
A small grid (3 traverses), 6km southwest of the main northern grid, was also targeted on an airborne EM anomaly, and returned anomalous MAGLAG Au values up to 44.5 ppb Au, supported by anomalous Cu (up to 189 ppm) and Zn (up to 706 ppm) values. The grid will be expanded to assess the full extent of these anomalous zones.

In conclusion , the preliminary assessment of the MAGSTREAM and MAGLAG geochemical data from the Barramine Project has confirmed the presence of significant base and precious metal anomalies that warrant follow-up. The recognition of base metal anomalies within the Carawine Limestone has provided encouragement for exploring for replacement or MVT-style base metal mineralisation.
The underlying Jeerinah mafic to intermediate volcanic stratigraphy includes volcanic agglomerate units consistent with an ancient volcanic centre that can be associated with VHMS-style copper-zinc-lead-goldsilver mineralisation. The geochemical data provides encouragement for this style of mineralisation with the presence of anomalous MAGSTREAM and fine fraction stream sediment samples in the area.
The Barramine Project is located in the East Pilbara and its geological position is along strike from known base metal deposits of Barramine, Camel Hump, Ragged Hills and Braeside. Previous exploration has discovered anomalous zinc and copper in highly altered pyritic acid volcanics in a prospective geological environment for base metal mineralisation.
