(25 May 2007) – Herald Resources Limited announced Dairi Zinc/Lead project – Exploration update.
SINAR PAGI
This prospect is located about 20km north from the Anjing Hitam ore-body. (Reserves 6.6MT @ 15% Zn, 9% Pb)
Diamond drilling commenced here in March and the initial hole SPA09D in the Main Lode zone, obtained a significant partly oxidized gross intercept of 28.6m @ 5.1 % Pb, 1.2% Zn & 78g/t Ag from 239m depth. Within this, two less oxidized, galena rich zones assayed 6.3m @ 14.5% Pb, 1.4% Zn, 193g/t Ag (6.2 oz/t); and 2.5m @15.1% Pb, 6.3% Zn & 267g/t Ag (8.6 oz/t).
In attempting to drill down dip from the latter, hole SPA10D encountered a large cavity, which forced abandonment of the hole.
The Main Lode zone is of a different style of mineralization to the “Julu sedex type” to be mined at Anjing Hitam to the south. It appears to be of stratabound quartz-sulphide replacement of dolostone and is more lead-silver rich than the zinc-dominant sedex style.
LAE JEHE
The Lae Jehe Prospect is located about 1.5km north of the Anjing Hitam orebody and 500m from the proposed concentrator site. With existing Resources of 6.5MT @ 11% Zn, 6% Pb, Lae Jehe is the most advanced target to provide future mill feed following the initial 7-year mine life at Anjing Hitam.
Lae Jehe Shallows
Follow-up drilling at the SE extremity of the Lae Jehe Shallows trend has resulted in success in hole SOP254D which intercepted two mineralized horizons 3.47m of massive sulphides from 75.5m depth and 2.62m of 70% sulphides intercalated with shale from 91 .6m depth. Assays are awaited. These intercepts are about 100m laterally removed from a wide outcrop of massive sulphides designated Sapurang Anton.
Another hole will be drilled from the same site to intercept the zone about 100m downdip. It is then proposed to test the zone 100m along strike to the SE.
Lae Jehe Deeps
Hole SOP253D, targeting the Upper Mineral Zone at 200m RL on Lae Jehe section 700N has obtained a massive sulphide intercept of 6.05m from 545.55m, not yet assayed. It is not certain yet which horizon has been intercepted and the hole is still in progress below this intercept.
Herald has 80 percent stake in Dairi project with state miner PT Antam holding the balance. (end of release)
