Significant Aircore Drilling Results
Sydney, Aug 21, 2012 AEST (ABN Newswire) - Thomson Resources Limited (
ASX:TMZ) is pleased to announce further results of its initial drilling program over the Achilles and Louth projects, near Cobar, NSW. Three prospects at Achilles and Louth (Figure 1) have been tested by traverse aircore drilling with anomalous results recorded on each; for two of these prospects this was the first drilling ever undertaken.
ACHILLES PROJECT
At the Mt Boorithumble prospect on the Achilles EL 7746 (TMZ is earning an 80% interest), 23 holes for 674m were drilled across three inferred mineralisation zones (Figure 2) which are interpreted to be possible Cobar-type zones with potential for high grade base and precious metal deposits.
The Mt Boorithumble prospect is a 900m long lead anomaly (max 0.24% Pb) defined by 240 shallow RAB holes. In 1981, a single diamond drill hole (LBO1) returned a best intersection of 3m @ 1.95% Pb, 2.0% Zn, 1.20% Cu and 150ppm Ag from 117m. Two interpreted mineralised zones, the central and western, were confirmed by the new drilling; drilling on the eastern zone was unsuccessful due to rock hardness.
The best results were recorded in the central zone with ACHAC032 returning 1m at 1,320 ppm (0.13%) lead, 499 ppm zinc from 18m. Also, a new zone was intersected between the central and western zones with ACHAC03 returning 4m at 671 ppm Pb from 16m.
A surface electro-magnetic (EM) survey will commence shortly to attempt to identify zones of massive base metal sulphides that may be present within these mineralised zones.
Also on EL 7746, the Achilles 3 prospect was tested by drilling for the first time. This 300m long soil anomaly with surface lead values up to 598 ppm Pb lies on rocky outcrops of rhyolitic sandstone (Figure 3) adjacent to the Achilles shear which extends for at least 10km to the south and is sporadically mineralised along its length.
The new drilling (10 holes, 139m) was highly encouraging, encountering strong lead - zinc - copper anomalism, with best results in ACHAC023 of 4m at 3,600 ppm (0.4%) Pb, 1090ppm Zn and 654 ppm Cu at a depth of only 4m. Generally drilling only reached very shallow depths (average 12m) and deeper testing is required to test the anomaly in fresh rock.
Further drill testing is warranted and will be included in a planned RC program.
LOUTH PROJECT
Significant zinc anomalism was detected at the third prospect on EL 6844 (Louth Road) to be drill tested. A new drill traverse (7 holes, 218m) tested a magnetic anomaly (Figure 4), 1.2km on strike north of the Ares gold prospect. The best result was in LOUAC06 with 4m at 1230 ppm Zn, 209 ppm Cu and 0.3 g/t Au from 40m depth in a weathered siltstone.
Several adjacent holes on the main magnetic anomaly did not penetrate a siliceous hardpan, and so the central part of the anomaly remains untested.
This is a significant result in a new area and worthy of follow up - further drill testing is planned.
