Chalice Gold Mines Limited Report New Results from Ongoing Exploration Activities
Chalice Gold Mines Limited report significant new results from ongoing exploration activities at its 100%-owned Julimar Nickel-Copper-PGE Project, located 70km north-east of Perth in Western Australia. Four rigs are continuing a step-out and resource definition drill program at the Gonneville Intrusion, where Chalice recently made a major high-grade PGE- Ni-Cu-Co discovery. A third RC rig is expected to arrive in the coming weeks. A total of 19 diamond drill holes and 88 RC drill holes have been completed to date at the project, of which assay results for 13 diamond and 59 RC holes have now been reported. Assay results are pending for a further 32 completed drill holes Recent RC drilling on a nominal 100-200m x 80m grid has tested the eastern margin of the Gonneville intrusion and intersected wide intervals of disseminated sulphides containing higher grade mineralised sub- intervals over a 1.2km strike length. This Eastern Contact position of the intrusion is 200-500m to the north- east, east and south-east of the previously identified high-grade G1-G4 Zones. Meanwhile, recent diamond drilling and subsequent geological interpretation has confirmed the presence of at least five high-grade (defined as >1.0g/t Pd cut-off grade) zones of mineralisation (G1-G5) around the discovery zone, which now extend over an area of 550m x 350m. Drilling to the west (down-dip of G1-G3) has so far been restricted by pending permitting approvals. The initial drill test of EM Conductor `X' is currently underway, with diamond hole JD018 currently at a depth of 690m. The hole has successfully intersected the Gonneville Intrusion from 428m, some 800m to the north- west of the G1-G5 Zones, which confirms that the intrusion extends beyond the limits of the 1.6km x 0.8km magnetic anomaly. JD018 has intersected disseminated sulphide mineralisation from 631m to 646m, based on visual logging, a highly encouraging result. All assay results are pending. Drilling results - Eastern Contact: The contacts or margins of the layered mafic-ultramafic Gonneville Intrusion are highly prospective target horizons for high-grade sulphide mineralisation. Several RC drill holes were recently completed on a nominal 200m x 80m hole spacing over the eastern contact of the Gonneville Intrusion to a nominal hole depth of 250m. Several new PGE-dominant mineralised intervals were intersected at relatively shallow depths along and proximal to the eastern contact over a 1.2km strike length. The intervals comprise trace to 3% disseminated sulphides enveloping zones of more abundant sulphides (locally to 5-20% sulphides). RC drill hole JRC011 was extended with a diamond tail (JRC011D) to test the continuation of this zone at depth and intersected a narrow mineralised interval: 2m @ 1.5g/t Pd, 0.9g/t Pt, 0.1g/t Au, 0.2% Ni, 0.1% Cu, 0.02% Co from 256m. The interval is outside of the intrusion in the underlying metasediments, the first indication of remobilised sulphide mineralisation at Gonneville. Remobilised sulphide mineralisation is commonly seen in other layered mafic-ultramafic systems, in some cases extending hundreds of metres from the host intrusion. As such, this first evidence of remobilisation at Gonneville is viewed as highly encouraging. RC drilling at the north-east margin of the intrusion intersected several broad intervals of disseminated sulphides, enveloping zones of more abundant sulphides (locally to 5-20% sulphides). JRC039 tested an off-hole EM anomaly at JRC003D, located 100m to the south, and intersected a zone of high-grade Ni-Cu rich massive sulphides: 4m @ 3.2g/t Pd, 0.6g/t Pt, 0.05g/t Au, 2.1% Ni, 0.8% Cu, 0.15% Co from 122m. This zone of high-grade massive sulphides is located along strike from a narrow zone of massive sulphides previously reported for JRC003 - 5m @ 2.4g/t Pd, 0.3g/t Pt, 0.7% Ni, 0.4% Cu, 0.05% Co from 143m. The Eastern Contact of the Gonneville Intrusion is cut by a series of Proterozoic dolerite dykes (post-mineralisation) and more infill drilling is required in this area to better understand the potential continuity of the mineralised intervals intersected to date. All new zones remain open in all directions and further infill drilling is planned along this contact. Drilling results - EM Conductor `F' Target: An initial program of 20 drill holes (18 RC and 2 diamond drill holes) recently tested the EM Conductor 'F' Target, located at the southern end of the Gonneville Intrusion. Drilling was completed on a nominal 100mx 80m spaced grid, with some holes oriented at sub-optimal azimuths due to surface restrictions. Assay results have been received for 7 drill holes only. Significant results include: 18.6m @ 2.1g/t Pd, 0.8g/t Pt, 0.2% Ni, 0.1% Cu, 0.02% Co from 240.4m (JD010); 33m @ 2.0g/t Pd, 0.4g/t Pt, 0.5g/t Au, 0.3% Ni, 0.8% Cu, 0.02% Co from 236m (JRC060); 6.0m @ 8.8g/t Pd, 0.2g/t Pt, 0.2% Ni, 0.1% Cu, 0.02% Co from 196m (JRC040). Mineralisation is hosted within serpentinite and locally along contacts with late granite intrusions. The new mineralised intervals are open in all directions. The southern end of the Gonneville Intrusion is cut by numerous post-mineralisation granitic and dolerite dykes and more infill drilling is required to better understand the continuity of mineralised zones. Drilling results - G1 and G2 Zones: As previously reported, JD013 was drilled 225m to the north-west of the discovery hole (JRC001) targeting the down-dip extension of the G1 Zone. Based on visual logging the hole was interpreted to have intersected a wide zone of matrix, minor massive and disseminated sulphides from 224m. Assay results have confirmed that a wide, high-grade interval was intersected: 45.1m @ 2.9g/t Pd, 0.8g/t Pt, 0.4% Ni, 0.3% Cu, 0.03% Co from 223.9m (JD013), including: 10.1m @ 3.2g/t Pd, 1.2g/t Pt, 0.4% Ni, 0.4% Cu, 0.03% Co from 223.9m; 10.6m @ 3.7g/t Pd, 1.2g/t Pt, 0.6% Ni, 0.3% Cu, 0.04% Co from 238.5m; and 11.0m @ 4.8g/t Pd, 0.8g/t Pt, 0.8% Ni, 0.4% Cu, 0.05% Co from 256m. This intersection was previously interpreted to be an extension of the G1 Zone; however, together with new drill results in the vicinity, the geological interpretation has been modified and the above mineralised interval is now interpreted to be part of the G2 Zone. As such, JD013 has extended the G2 Zone 60m down-dip and the zone remains open. JD011, an infill hole drilled 80m north of JRC001, intersected the re-interpreted G1 Zone, as well as the deeper G2 Zone: 8.0m @ 5.1g/t Pd, 0.8g/t Pt, 0.3% Ni, 0.1% Cu, 0.02% Co from 98m (JD011) - G1 Zone; and 9.8m @ 1.4g/t Pd, 0.3g/t Pt, 0.3% Ni, 0.5% Cu, 0.02% Co from 135.2m (JD011) - G2 Zone.
