Lake Resources N L, Quarterly Report, April - June 2012
LAKE RESOURCES NL QUARTERLY REPORT APRIL–JUNE 2012
==> picture [65 x 65] intentionally omitted <==
SUMMARY
During the quarter ended 30[th] June 2012, a seventeen hole reverse circulation (RC) drilling program totaling 2,070m was completed at the Koh-i-Sultan Project in Balochistan, Pakistan.
Pakistan
Lake Resources (Lake) is exploring for porphyry copper-gold and epithermal gold deposits in the Chagai District of Balochistan (see p.2 for details). Significant mineral deposits in the region include the Saindak porphyry coppergold mine and the Reko Diq copper-gold project of Antofagasta Plc and Barrick Gold Corporation.
Lake Resources holds three Exploration Licences (ELs) granted by the Government of Balochistan in September 2009. These ELs replaced previous ELs held by Lake that expired in March 2009. Details are set out in Table 1 and Figure 1 below.
Table 1: Balochistan Tenements
| Tenement | **Amalaf ** | **Dasht-i-Gauran ** | **Koh-i-Sultan ** |
|---|---|---|---|
| **EL Number ** | (71)/5468-78 | (72)/5492-5503 | (73)/5479-91 |
| Area (sq km) | 94.42 | 58.76 | 171.40 |
| Lake Interest | (see Note 1) | (see Note 1) | (see Note 1) |
| Grant Date | 10/09/2009 | 10/09/2009 | 10/09/2009 |
| Expiry Date | 9/09/2012 | 9/09/2012 | 9/09/2012 |
Note 1: A condition of the new licences is that the Balochistan Government should have up to a 25% interest in the licences – the government advises that preparation of a draft agreement is under way.
During the June quarter, applications for renewal of the ELs over reduced areas for a further period of 3 years were lodged with Government of Balochistan as per Balochistan Mineral Rules.

The Amalaf area adjoins the northern boundary of the Saindak copper-gold mine. The exploration target is large tonnage - low grade copper amenable to low-cost open-pit mining and trucking to the Saindak mine. In late 2005, one of two holes drilled by Lake to test part of this target intersected significant low-grade copper-molybdenum over the length of the hole with minor gold (12 -120m, 108 m @ 0.17%Cu & 94 ppm Mo).
The Dasht-i-Gauran area is situated to the west of copper mineralisation reported by TCC from drilling at its Sor Baroot Prospect at the Reko Diq Project, and covers a number of possible alteration zones identified from interpretation of satellite images.
At Koh-i-Sultan , Lake is exploring an extensive system of intensely altered breccia and volcanics covering an area of more than five square kilometres on the margin of an extinct volcanic caldera (See Fig. 2). Strong gold mineralisation was intersected in percussion drillhole LRM-01 on the western margin of the system in late 2005.
A five-hole diamond drilling program totaling 2284 m was completed in August 2008 (See Figs. 2 & 3 for drillhole locations). That program resulted in two new discoveries:
-
porphyry-type copper-gold mineralisation in drillhole LRMDDH-002 (392 – 520 m, 128 m @ 0.14%Cu and 0.19 ppm Au) and
-
a very large, variably-altered and mineralised breccia complex, intersected in all five drillholes, over a width of more than 700 m and a north-south extent of more than 400 m. Geologically significant gold values were intersected in the breccia in four of the five drillholes. It is believed that the southern extension of this breccia also hosts the gold mineralisation intersected in drillhole LRM-001.

Exploration
During the quarter ended 30[th] June 2012, a seventeen-hole reverse circulation (RC) drilling program totaling 2,070 metres was completed at the Koh-i-Sultan project. The drilling, which was originally scheduled for 2011, was delayed due to the unavailability of suitable drilling equipment in Pakistan and the equipment had to be specially shipped from Australia by Interdrill Pty Ltd. The holes are located within an area approximately 1,000 metres eastwest by 1,500 metres north-south, along Miri Nala, southwest of Nawah Caldera (See Figure 3).

The drilling equipment comprised a crawler-mounted multi-purpose (diamond coring and percussion) drill and a crawler-mounted air compressor (900 cfm @ 350 psi) (See Fig. 4)

A number of the RC drillholes were terminated before reaching planned depth when they encountered potentially lethal concentrations of pressurized H2S gas (see Table 2 above). H2S gas is a naturally-occurring, colourless gas with a “rotten-egg” smell at low concentrations. At higher concentrations, exposure to the gas can result in loss of consciousness and death within a short time. Several other holes were also terminated early when they encountered hot water which was considered to be indicative of the likelihood of encountering H2S if drilling continued.
Samples were collected continuously via a cyclone splitter (see fig. 4 above) for 2 metre intervals – 2 sample splits of approximately 1-2 kg in cloth bags and the remaining bulk in large UV-resistant plastic bags. One set of the 1 kg samples was packed in sealed plastic drums and air-freighted to ALS Laboratories in Brisbane for geochemical analysis. The duplicate 1-2 kg samples have been stored at the Nok Kundi exploration base for future reference. The bulk samples in plastic bags have been retained at the drill sites.

To date, alternate samples (i.e. every second sample) from all drillholes have been subjected to multi-element analysis - 49 elements including silver base metals and a range or rare earths and trace elements by ICPAES and ICMP analysis, and gold by fire assay with AAS finish. The remaining alternate samples from selected zones will be analysed during the next quarter for the same suite of elements, to provide complete geochemical data for zones of interest.
Based on results to date, it is possible to draw some preliminary conclusions.
With the exception of holes LRMRC 004 and 006, the majority of the holes intersected variably altered volcanics and breccia(?) containing geochemically anomalous levels of trace elements and metals consistent with alteration marginal to porphyry copper mineralization that was intersected in 2008 diamond drillhole LRMDDH-005 (See Fig. 3).
At the southern end of the area drilled, in the vicinity of the 2005 gold-mineralised drillhole LRM-01, significant gold was intersected four drillholes:
LRMRC-003 66 - 88 m anomalous gold up to 0.16 g/t in altered volcanics. LRMRC-005 90 - 130 m anomalous gold ranging 0.05 to 0.14 g/t with one sample 0.63 g/t. LRMRC-018 02 – 12 m anomalous gold ranging 2.67 to 3.57 g/t averaging 3.16 g/t (+0.45% copper). LRMRC-019 02 – 20 m anomalous gold ranging 1.05 to 2.19 g/t averaging 1.73 g/t (+0.20% copper). “ “ 58 – 68 m anomalous gold ranging 2.74 to 11.8 g/t averaging 5.24 g/t.
A more detailed evaluation of the results of the drilling will be undertaken following the completion of analyses for the remaining alternate samples referred to above during the next quarter.

At the end of the June 2012 quarter, net cash on hand totaled A$520,000.
