(MENAFN - ProactiveInvestors - Australia) Consolidated Tin Mines (ASX: CSD) has discovered five new anomalous tin zones through soil sampling at its Mt Garnet Tin Project area in northern Queensland.
The new tin zones were identified from a recently completed hand held XRF soil geochemical program within the Mount Garnet area.
Sampling tested the highly prospective contact between O'Briens Creek supersuite granites and the Hodgkinson Formation.
Rock chip and mine waste grab samples collected from these anomalous zones returned significant anomalous tin values.
The most significant anomaly identified during stage one of the soils program occurs within the Crisis area, where a broad, strong tin anomaly was identified in an area associated with historical mining.
The Crisis anomaly returned a several soil samples reading greater than 1,000 parts per million up to 2,150 parts per million tin.
Strongly anomalous samples were discovered over an area of 1 by 1.5 kilometre, with rock chip and grab samples within the anomaly area grading up to 20% tin " based on handheld XRF.
Historical drilling in this area in 1976 by Western Mining intercepted 13 metres at 0.66% tin from 84.25 metres, including 6.75 metres at 1.03% tin; and 4.4 metres at 0.53% tin from 13.1 metres, including 1 metre at 1.65% tin.
The anomaly identified in the Sailor Valley area corresponds to an area where historical drilling also intercepted strong tin anomalism.
The Sailor Valley anomaly remains open and is the strongest of the five anomalies identified during the initial soils program. Its smaller size rates it behind Crisis in potential.
The Sailor Valley anomaly is defined by consistently high (greater than 1000 parts per million) tin anomalism (up to 3,300 parts per million) over a 400 metre long by 250 metre wide zone which is open to the north and south.
Minimal historical drilling by Newmont produced best intercepts of 3 metres at 1.09% tin.
In the Never Can Tell area, a prominent northwest to southeast trending magnetic anomaly and historical costeans are associated with a number of 150 to 400 metre long, 10 to 50 metre wide greisen zones.
This greisenised contact between granite and metasediments at Never Can Tell represents a significant target.
The soil anomaly extends over a 200 metre long by 500 metre wide zone which remains open to the south.
The anomaly is defined by historical costeans and moderate to strong tin anomalism (up to 3,900 parts per million tin by hand held XRF), where stronger results are associated with siliceous greisen veins in outcrops containing course cassiterite.
There has been no historical drilling at the Never Can Tell Prospect.
The Coolgarra anomaly occurs in an area where a number of historical mines and costeans exist.
The Alhambra Mine, consisting of three main shafts, two adits and a number of smaller workings, remained in operation throughout the 1800s up to 1906 producing 21,600 tonnes of tin ore (435 tonnes of tin oxide).
The Coolgarra anomaly is defined by historical mining, significant drill intercepts from previous drilling by Consolidated Tin Mines, and strong tin anomalism (ranging up to 2,560 parts per million) over a broad zone.
High grade rock chip and grab samples have also been returned from the anomaly.
Lastly, the weakest of the anomalies identified during stage one of the soils program occurs in the Top Nettles region.
This anomaly is indicated by a broad area where three 500 metre spaced sample lines picked up moderate to strong tin anomalism.
The Top Nettles anomaly is defined by moderate to strongly anomalous tin (ranging up to 2,700 parts per million tin) on at least three lines; rock chips and grab samples with significant tin values; and numerous historic small tin workings in Top Nettles area.
Stage two of the program will involve infill and line extensions at all five targets, followed by targeted drilling aimed at defining additional resources.
