QUARTERLY REPORT JULY–SEPTEMBER 2012
==> picture [65 x 65] intentionally omitted <==
SUMMARY
During the quarter ended 30[th] September 2012, geochemical analyses were completed for the 17-hole reverse circulation (RC) drilling program undertaken earlier in the year at the Koh-i-Sultan Project in Balochistan, Pakistan. The results of the drilling support potential for gold and porphyry copper-gold deposits indicated by previous Lake Resources drilling – a substantial program of deeper diamond drilling is required to test these targets. Renewals of the three Exploration Licences over reduced areas were granted for a further three years.
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. During the September 2012 quarter, applications for renewal of the ELs over reduced areas for a further period of 3 years were granted by Government of Balochistan as per Balochistan Mineral Rules. Details are set out in Table 1 and Figure 1 below.

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] September 2012, geochemical analyses were completed for the 17-hole reverse circulation (RC) percussion drilling program undertaken earlier in the year at Koh-i-Sultan. The drillholes are located within an area approximately 1,000 m east-west by 1,500 m north-south, along Miri Nala, southwest of Nawah Caldera (Figure 3). Drillhole location and orientation details are set out in Table 2 below.

During the previous quarter, alternate 2 m samples from all drillholes were 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. Following preliminary evaluation of the initial analyses, the remaining alternate samples from selected zones in some drillholes were analysed for the same suite of elements to provide continuous geochemical data for geochemically anomalous zones.

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).
Drillhole chip samples were collected continuously via a cyclone splitter (see fig. 4 above) for 2-metre intervals – two 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.

Drilling Results
At the southern end of the area, in the vicinity of the gold intersection in 2005 drillhole LRM-01, seven holes were drilled in variably altered volcanics and breccia. Five of these holes (LRMRC 005, 006, 007 &009) were essentially barren except for patchy elevated levels of manganese.
However, significant gold was intersected in four drillholes, with associated copper in two of these holes, similar to drillhole LRM-01:
| LRMRC-003 | 64 – 90 m | anomalous gold in 2 intervals: |
|---|---|---|
| 64 – 68 m | 4 m @ 0.17 g/t Au | |
| 74 – 90 m | 16 m @ 0.14 g/t Au | |
| LRMRC-005 | 90 – 134 m | anomalous gold in 4 intervals: |
| 90 – 92 m | 2 m @ 0.11 g/t Au | |
| 96 – 100 m | 4 m @ 0.29 g/t Au | |
| 106 – 112 m | 6 m @ 0.13 g/t Au | |
| 124 – 134 m | 10 m @ 0.43 g/t Au | |
| LRMRC-018 | 02 – 16 m | 14 m @ 2.20 g/t Au & 0.32% Cu, including: |
| 02 – 12 m | 10 m @ 2.96 g/t Au & 0.44% Cu | |
| and | ||
| 68 – 72 m | 4 m @ 0.19 g/t Au | |
| LRMRC-019 | 02 – 78 m | anomalous gold over the complete hole (average 1.47 g/t Au) with copper in the |
| top 18 m including: | ||
| 02 – 22 m | 20 m @ 2.23 g/t Au & 0.18% Cu | |
| 22 – 58 m | 36 m @ 0.27 g/t Au | |
| 58 – 70 m | 12 m @ 4.53 g/t Au | |
| 70 – 78 m | 8 m @ 0.39 g/t Au |
To the north, drillholes LRMRC 010 – 17 intersected zones of geochemically anomalous levels of molybdenum (>5 ppm up to 130 ppm) and copper (>300 ppm up to 1675 ppm). Minor gold was intersected in some of these drillholes:

(Cutoff grade used for the above intersections is 0.10 g/t Au).
Conclusions
Results of the 2012 RC percussion drilling indicate potential for:
-
a significant gold target, with possible supergene copper in the LRM001 – LRMRC003/005/018/019 area. The copper-gold association in some of these holes could indicate potential for porphyry copper-gold mineralization beneath this area.
-
a large porphyry copper-gold target associated with the porphyry copper-gold intersection in 2008 drillhole LRMDDH002, supported by the intersections of elevated levels of molybdenum, copper and patchy gold in RC percussion holes LRMRC010 – 017.

Lake Resources N L, Quarterly Report, July - September 2012
A substantial program of deep diamond drilling (500 – 600m) is required to test these targets below the levels achievable with RC drilling.
A planned RC drilling program at the Amalaf Exploration Licence area that was scheduled for the second quarter 2012, was postponed as a result of a new Government of Pakistan policy requiring security clearances for expatriate personnel engaged in exploration activities in this region. Application for these clearances is in progress.
Cash Position
At the end of the September 2012 quarter, net cash on hand totaled A$403,000.
