Magma Metals Limited: High Grade Drill Intercepts From EM Targets in the Bridge Zone at Thunder Bay North
Press Release Source: Magma Metals Limited On Wednesday July 21, 2010, 9:00 am EDT
PERTH, WESTERN AUSTRALIA--(Marketwire - July 21, 2010) - Magma Metals Limited (TSX:MMW - News; ASX:MMW - News; "Magma" or the "Company") is pleased to advise that drilling to test electro-magnetic (EM) anomalies in the Bridge Zone intersected several high grade mineralized zones at the Thunder Bay North platinum-palladium-copper-nickel project in northwest Ontario.
Bridge Zone EM targets
Extensive down-hole electro-magnetic (DHEM) surveys in the Bridge Zone were completed in the June quarter to map potential high-sulphide zones near the base of the mineralized mafic-ultramafic intrusion. Many anomalies were identified and modelled and 12 of these were prioritized for drill testing (Figure 1). Drilling is in progress and assay results have been received for the first five holes, which returned the following excellent intercepts:
BL10-326: 51.0m @ 5.02g/t Pt, 4.84g/t Pd, (9.86g/t Pt+Pd),
1.18% Cu & 0.56% Ni from 85.1m,
including 8.6m @ 11.55g/t Pt, 10.81g/t Pd, (22.36g/t Pt+Pd),
2.80% Cu & 1.27% Ni from 127.5m,
including 1.1m(i) @ 23.40g/t Pt, 22.80g/t Pd, (46.20g/t Pt+Pd),
6.80% Cu & 3.76% Ni from 135.0m;
BL10-328: 23.5m @ 4.20g/t Pt, 3.80g/t Pd, (8.00g/t Pt+Pd),
0.85% Cu & 0.39% Ni from 123.25m,
including 8.5m @ 6.23g/t Pt, 5.73g/t Pd, (11.96g/t Pt+Pd),
1.21% Cu & 0.61% Ni from 128.25m;
BL10-329: 21.0m @ 2.37g/t Pt, 2.12g/t Pd, (4.49g/t Pt+Pd),
0.54% Cu & 0.25% Ni from 156.1m,
including 9.5m @ 3.78g/t Pt, 3.32g/t Pd, (7.10g/t Pt+Pd),
0.80% Cu & 0.31% Ni from 157.1m;
BL10-330: 11.5m @ 2.08g/t Pt, 1.96g/t Pd, (4.04g/t Pt+Pd),
0.46% Cu & 0.26% Ni from 172.2m,
including 1.5m @ 5.79g/t Pt, 5.33g/t Pd, (11.12g/t Pt+Pd),
1.15% Cu & 0.36% Ni from 177.2m,
and 0.5m(i) @ 5.18g/t Pt, 5.49g/t Pd, (10.67g/t Pt+Pd),
1.26% Cu & 0.85% Ni from 183.2m;
BL10-332: 21.5m @ 2.98g/t Pt, 2.40g/t Pd, (5.38g/t Pt+Pd),
0.61% Cu & 0.25% Ni from 156.35m,
including 6.5m @ 8.95g/t Pt, 7.10g/t Pd, (16.05g/t Pt+Pd),
1.80% Cu & 0.51% Ni from 171.35m,
including 0.50m(i) @ 71.0g/t Pt, 47.8g/t Pd, (118.8g/t Pt+Pd),
14.40% Cu & 2.38% Ni from 176.85m.
((i)Contains massive sulphide interval)
Results are detailed in Tables 1 and 3.
"These results are very encouraging, particularly for hole BL10-326, which is amongst the best drill intercepts recorded at the project. Once we have received the remaining results from drilling the EM targets, we will plan a close-spaced drilling program to carefully delineate the high-sulphide zones defined by this program and previous drilling in this area," said Keith Watkins, Magma's Executive Chairman. "These zones have the potential to form a high value domain within the existing mineral resource and it's important to accurately define their shapes by drilling so that we can estimate their tonnages and grades".
High sulphide zones generally comprise heavily disseminated to semi-massive (net-textured) sulphides, which may overlie a massive sulphide unit. The high sulphide zones are generally associated with trough-like depressions in the floor of the mafic-ultramafic intrusion and appear to form linear bodies and pods. There have been 15 intersections of massive sulphide units, with down-hole thicknesses ranging from 0.1 to 2.6m, from drilling so far in the Bridge Zone and the western Beaver Lake Zone, including four from this program (assays are pending for one of these) (Figure 1).
Other Bridge Zone Targets
Drilling has also been completed in the Bridge Zone to test interpreted depressions in the floor of the intrusion for potential sulphide accumulations and to define the edges of the mineralized zones in a number of areas (Figure 1). Results have been received from some of this drilling and are detailed in Tables 2 and 3.
In addition, exploration drilling is in progress to test magnetic targets adjacent to the Bridge Zone which could represent lateral extensions or branches of the mineralized mafic-ultramafic magma conduit (Figure 1).
Elsewhere in the project, a drilling program is in progress to test a number of regional targets including magnetic anomalies in the South East Anomaly (south-eastern part of the Current Lake Intrusive Complex), and the Lone Island Lake Intrusive Complex in the western part of the project. Any significant results from this program will be reported in due course.
The mineral resource estimate update being undertaken as part of the current Scoping Study is in progress and on schedule with planned completion in the September quarter, 2010. The Scoping Study is scheduled for completion in the December quarter, 2010.
