ASX Announcement (ASX: HMX)
28 July 2017
EXPLORATION UPDATE
Hammer Metals Limited (Hammer or the Company) (ASX: HMX) wishes to provide an update on current exploration activities over its Mount Isa Project in Northwest Queensland.
-
RC drilling program has commenced at the Kalman West and Revenue copper-gold prospects.
-
Follow-up of VTEM anomalies identifies 12 potential drilling targets; highlighting a zone of elevated gold soil and rock chip geochemistry along a 1.2km strike length of the Pilgrim Fault in the Serendipity area.
-
The Dronfield RC and diamond drilling program to test the western and eastern geophysical anomalies was completed and final assays received. Strong magnetite veining and alteration with sporadic lowgrade copper mineralisation intersected in each hole coincident with the geophysical anomalies.
Planned RC Drilling Program
RC drilling has commenced at the Kalman West Cu-Au-Pb-Zn(-graphite) Prospect and the Revenue Cu-Au Prospect southeast of Mount Isa.
Revenue is located 30km southwest of Kalman in a similar geological and structural position as Overlander 28 km to the north. Up to three holes are planned to test a zone of Cu-Au mineralisation.
Kalman West is located approximately 1km west of the Kalman Cu-Au-Mo-Re Deposit. Geochemical sampling has outlined a multi-element soil anomaly partially coincident with a zone of graphitic schist and a high priority VTEM target. Up to five holes are planned at the prospect to test a combined soil anomaly which has peak values of 210ppb Au, 900ppm Cu, 1100ppm Zn and 2000ppm Pb.
Initial assay results are expected to be received in mid to late August.
The planned RC drilling at Hammertime has been deferred whilst an assessment of the broader Mount Philp breccia project which encompasses Hammertime is conducted.
Pilgrim Fault VTEM Survey – Target Review
An airborne VTEM Max (Versatile Time Domain EM) and magnetic survey over a 23km strike length of the Pilgrim Fault corridor extending from China Wall in the north to Python in the south was completed by Geotech International in late 2016.
Field investigation of the anomalies interpreted by Southern Geoscience is now complete with several of the target areas considered sufficiently prospective to warrant either drilling or further definition and assessment.
During field inspection, observations were recorded at 994 sites and 158 rock chip samples were collected. Copper mineralisation or iron oxide gossan was observed in thirteen areas.
1
The VTEM anomalies typically, but not always, occupy zones of carbonaceous siltstone, mica schist or graphitic schist. These zones have recessive topography and recent cover that complicates surface geochemical assessment. Further sampling and partial leach assay is recommended for selected covered areas.
Contacts between these recessive, conductive units and adjacent competent units such as calc-silicates or igneous rocks attract north-south shearing and alteration. Copper +/- gold mineralisation frequently occurs along these contacts, offset from the VTEM anomalies by up to 200m. Sometimes a causal relationship between the VTEM targets and the alteration and mineralisation is not readily apparent.
Twelve areas are currently considered potential drill targets. Additional targets are prospective but require further sampling and assessment due to subtle anomalism or alluvial / colluvial cover. Most of these targets could be tested with angled RC drillholes of between 100m and 250m depth.
Anomalies of particular interest include:
China Wall
At PF2 , 8km north of Kalman, discordant shears dilate the copper mineralised contact between carbonaceous metasediments and calc-silicates. A 400m long sheared outcropping alteration zone has drill potential, with scope for strike-extensions under cover. The area exhibits sporadic soil copper and gold anomalism, and reconnaissance rock chips samples returned up to 3.2% Cu, 0.47g/t Au, 3.3ppm Ag, 1320ppm Ce, 730ppm La and 9ppm Sn.
PF1, A gabbro body 400m northwest, has a coherent soil copper anomaly and contains scattered hematite and malachite alteration. Rock chip sampling returned up to 15% Cu and 0.88g/t Au. The area is under consideration as a drill target.
PF12 is situated on a folded carbonaceous metasediment / calc-silicate contact. A discordant soil Cu, Au anomaly 100m west near a granite contact coincides with rock chip assays up to 12% Cu and 0.33g/t Au and 4.4ppm Ag. The area is slated for further field assessment and extension sampling with a view to drill testing.
Pharaoh East
PF24 is situated on a bend in the Kalman Shear, 3km north of Kalman. Historic copper workings are accompanied by anomalous Cu and Au in soils and rock chips with up to 5.2% Cu and 0.51g/t Au. The area hosts strong redrock and magnetite alteration. The old workings are a drill target and 500m of strike to the south is slated for further assessment.
Pharaoh
At the Pharaoh prospect two groups of historic copper workings occur along the Kalman West shear zone, 3km north of Kalman. Alteration and copper mineralisation is focused on the intersection of the northstriking Kalman shear with north east striking cross faults. Sporadic soil Cu and Au anomalism coincides with rock chip assays of up to 14% Cu and 2.6g/t Au. Kings Minerals tested the southern group with one drillhole (K-115), returning up to 0.90% Cu and 1.0g/t Au over a one metre interval. The mineralisation is interpreted as occupying steep narrow shoots, which may not have been effectively tested. The richer northern group has not been drill-tested and is under consideration for future drilling.
2
Kalman West
PF5 occupies part of a 5km long graphitic schist zone hosting the Kalman West Shear. A broad, dilated schist zone with quartz veining occupies an 800m long sinistral jog in the shear zone, sandwiched between felsic intrusive bodies. This dilation zone appears to be part of a large north east trending zone of cross faulting and dilation that extends through to the Kalman deposit. Copper anomalism along the western schist contact has been partially drill-tested. The schist package has been targeted for future RC drill-testing and metallurgical sampling for Cu, Au, Pb and graphite.
Pelican
PF20, 21 & 23 occupy a 1.7km long zone of carbonaceous metasediments and calc-silicates with significant folding and displacement adjacent to the regional Pilgrim Fault. Coherent soil and rock chip Cu and Au anomalies also include Mo, Sn and U anomalism indicative of Kalman-style mineralisation. The anomalous areas have been tested with several short historic drill campaigns with mixed results. PN205C drilled by Mount Isa Mines Ltd in 2008 returned a best intercept of 24m @ 1.0% Cu, 0.34g/t Au from 28m, including 10m @ 1.6% Cu, 0.49g/t Au from 30m. Rock chip assay results include 22% Cu and 6.7g/t Au.
Recent reconnaissance mapping indicates that previous drill planning may not have adequately accounted for the structural complexity. The area is being re-assessed with a view to future drill-testing.
Serendipity
VTEM targets PF25 & 8 are situated near copper-gold mineralised carbonaceous siltstone along the Pilgrim Fault at the Serendipity prospect. The mineralised zone has been drill-tested on one section. An intercept of 25m @ 0.5g/t Au from 137m in K-90 (including 1m @ 2.3g/t Au), the easternmost hole on the section coincides with the Pilgrim Fault quartz veining.
Additional rock chip sampling returned several anomalous results up to 2.6g/t Au along the trend. One of the anomalous areas at the northern end of the trend also returned highly anomalous copper values and the light REE’s cerium (up to 3550ppm) and lanthanum (up to 1860 ppm). The gold anomalism in the rock chips and soils extends for 1.2km along the fault.
PF26 features a copper-mineralised shear along a quartzite / carbonaceous metasediment contact 1.4km south of the Serendipity prospect. The target structure outcrops for 300m and disappears under cover in both directions. Reconnaissance rock chip samples returned assays of up to 2.7% Cu and 0.76g/t Au. The target is under consideration for drill-testing and further assessment of covered extensions is recommended.

Dronfield Drilling Program
The three-hole diamond and RC drilling program at the Dronfield copper-gold project southeast of Mount Isa was completed in mid-July. A total of 1010 metres of diamond and 246 m of RC were drilled in the three holes.
The Dronfield targets are located 25km southeast of Kalman on EPM 18084, which is subject to a farm-in agreement with Kabiri Resources Pty Ltd. Hammer has earned an 80% interest in EPM 18084 from Kabiri by spending $250,000 on exploration. The tenement forms part of the Farm-in and Joint Venture Agreement with Newmont Exploration Pty Ltd. This drilling will be partially subsidised by a $100,000 Collaborative Drilling Initiative (“CDI”) Funding Grant from the Queensland Department of Natural Resources.
The first two (diamond) holes tested the western geophysical anomaly and the third RC hole tested the eastern geophysical anomaly. Both diamond holes, HDD001 (537m) and HDD002 (473m) intersected strongly magnetite-actinolite and red rock altered granodiorite of the Wimberu Granite (part of the Williams Batholith) over large parts of the hole. The alteration is consistent with other IOCG deposits in the region. Sulphide mineralisation where present is dominantly pyrite-chalcopyrite with levels generally ranging between trace to 1% with thin zones (<5m) where the total sulphide content can approach 5% in total. HDRC004, which was drilled into the eastern anomaly, intersected magnetite and red rock altered granodiorite with microgranite lenses.
Significant results from the program are tabulated below.
