Intrepid Mines Limited: Mumbwa Project - Target H Delivers Further Encouraging Copper and Gold Results
SYDNEY, AUSTRALIA--(Marketwired - Nov. 16, 2015) - Intrepid Mines Limited (IAU.AX) ("Intrepid" or the "Company") is pleased to provide an update on drilling at the Mumbwa Project in west-central Zambia.
Assays from drilling on Target H have delivered further encouraging results. Results from Kantonga, Kitumba and Target J are also presented here.
Highlights from Target H HDD_004 include:
51 metres at 0.91% copper and 0.32 g/t gold from 229 metres including:
23 metres at 1.60% copper and 0.58 g/t gold from 233 metres
20 metres at 0.48% copper and 0.21 g/t gold from 308 metres.
4 rigs, 3 diamond rigs and RC rig, are currently operating with approximately 10,700 metres of drilling having been completed to date.
Lulu, Target H and Kantonga are now the highest priority areas for future exploration.
Drilling at Kakozhi has shown some limited indication of mineralisation. A final hole is currently being drilled.
Further results from the current program will be released as they are received.
The Company's CEO, Scott Lowe, said:
"We continue to be encouraged by results from Target H, and look forward to releasing results from Lulu and further results from Kantonga once received. We are particularly pleased to have identified mineralised areas outside of Kitumba and follow-up drilling will be planned and prioritised once these results have been analysed."

HDD_002 - ASSAY RESULTS
HDD_002 was drilled on an azimuth of 130, inclined 60 degrees to a depth of 263.9 metres. This hole was drilled opposite HDD_001 targeting the Target H copper in soils anomaly and an IP geophysical anomaly. No intersections above the cut-off criteria are reported.
A series of 60 samples, including quality control samples, were submitted to the laboratory for analysis.
HDD_003 - ASSAY RESULTS
HDD_003 was drilled on an azimuth of 330, inclined 60 degrees to a depth of 458.3 metres. This hole was drilled approximately 100 metres to the south of HDD_001 and was targeting the Target H copper in soils anomaly and an IP geophysical anomaly. The best intercept includes 26 metres at 0.36% copper from 42 metres. Best single metre assays include 0.54% copper at 63.9 metres.
A series of 115 samples, including quality control samples, were submitted to the laboratory for analysis.
Final results having passed QA/QC are summarised here.

KANDD_001 - ASSAY RESULTS
KANDD_01 was drilled on an azimuth of 048, inclined 60 degrees to a depth of 605 metres. This hole was drilled on the large Kantonga anomaly which has zones anomalous in copper in soils, Induced Polarisation and airborne Magnetic and Gravity datasets. No intersections above the cut-off criteria are reported.
A series of 456 samples, including quality control samples, were submitted to the laboratory for analysis.
KITDD_071A - ASSAY RESULTS
KITDD_071A was drilled on an azimuth of 240, inclined 80 de.grees to a depth of 711 metres. This hole was drilled targeting an Orion 3D IP chargeability anomaly at depth (390 metres) to the northwest of the Kitumba deposit (approximately. 750 metres). The Orion 3D IP dataset was acquired during the 2012 field season. The chargeability anomaly can be explained by an increase in sulphides (pyrite) at the target depth. The best intercept includes 4 metres at 0.32% copper from 556 metres.
A series of 375 samples, including quality control samples, were submitted to the laboratory for analysis.

JRC_001 - ASSAY RESULTS
JRC_001 was a reverse circulation (RC) hole drilled on an azimuth of 300, inclined 65 degrees to a depth of 180 metres. This hole was designed to test a soil geochemical anomaly and coincident magnetic and gravity anomalies. No intersections above the cut-off criteria are reported.
A series of 33 samples, including quality control samples, were submitted to the laboratory for analysis.
2015 (PHASE 9) DRILLING PROGRAM
Three diamond rigs and an RC rig are currently onsite and drilling the final holes for the 2015 season. Approximately 12,500 metres of diamond core and RC drilling will have been completed at the end of this program with results expected to be continually coming in through till the end of Q1 2016. Clear priority targets in Target H, Kantonga and Lulu have been generated in this field season requiring further work including drill testing in future programs.
NOTES:
Sampling and assaying of the drill core and RC chips collected follows a standard site protocol with samples being submitted to the Intertek Genalysis Laboratory preparation facility in Chingola, Zambia before being shipped to the Intertek Genalysis Laboratory in Perth, Australia for analysis.
A total of 48 elements were analysed. Multi-element analyses were performed using a multi acid digest (Hydrofluoric, Nitric, Perchloric, Hydrochloric) with Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma - Optical Emission Spectroscopy (ICP-OES, including copper) analyses. Gold analyses were performed using 25g lead collection fire assay with an Flame Atomic Absorption Spectroscopy (AAS) finish. All analyses were completed by the fully NATA-accredited Intertek Genalysis Laboratory in Perth, Australia.
A Quality Assurance/Quality Control ("QA/QC") program includes chain of custody protocol, a systematic submittal of 20% QA/QC samples including field duplicates, field blanks and certified reference samples into the flow of samples submitted to the laboratory and submission of samples for umpire analysis by a second accredited laboratory.
A cut-off grade of 0.25% copper, a maximum internal dilution of 2 metres (drilled thickness) and a drilled thickness of >2 metres are used as guidelines when delineating the drilled thickness intervals of mineralisation, with length-weighted average grades reported. True-widths are not quoted. No upper limit has been applied to copper grades in these exploration results.
