1. Highlights and Productivity

Overview pan sampling on target Areas 1 and 2. Some gold dispersion has been

detected especially in target 2

Channel sampling and Trench Mapping conducted on previous Trenches resp. 8, 9 and

27 has revealed some interesting geological features in this area.

PANSAMPLING RESULTS

A total of 19 locations were sampled during the period, mostly within the drainages in target-

1 as depicted in figure 2. Mechanical failures on the ATV and other logistical issues slowed

progress.

Results indicate that the highest values are recovered in target 2 with value as high as 23 gold

colors. The area in target-2 is characterized by steep hills which exhibit a ferruginous clay

soil on surface surrounded by lower topographical relief with exposures of large boulders of

Leuco-granite can be observed. Furthermore evidence of shear deformation was also

recorded striking 320 degrees and dipping steeply.

Target-1 has only shown minor indication of gold colors within the drainages sampled as

shown in figure2. The present of gold mineralization in this region has also been confirmed

by previous soil geochemistry, done along the ridges of the hills. (see figure 2)

MEMO

The following outcrops were encountered in this area.

1. Intermediate to mafic volcanics, showing often pahoehoe lava flow foliation intercepted

within and near the banks of the Tibiti River.

2. Quartzite boulders on slope area

3. Boulders of Quartz Arenite to the west.

No old or new pk workings were encountered within the drainages of both target areas.

TRENCH SAMPLING

Channel sampling has also been conducted across shallow dipping geological features exposed

especially within Trench 08. Additionally some channel samples are from Quartz veins or other

significant structural features that were not sampled in previous work.

TRENCH: TR08A

Trench TR08A is located in the NW corner of Trench TR08 on a hill top. Exposures on the wall

show shallow dipping, slightly folded strongly oxidized to hematic layers within massive

ferruginous host rock. These layers shows no evidence or remnants of quartz veins. Vertical channel

sampling was conducted across these structures and 17 samples were collected in total. Saprolite

encountered indicates the presence of mafic intrusive to volcanics in this area.

TRENCH: TR08

The first 13 meter of the most southern part of Trench 08 consist primarily of a reddish ferruginous

massive clay soil with the presence of some laterite nodules and pisoliths. To the north, gradually

indication of saprolite could be distinguished mainly on the lower half of the wall and are described

as purple to red brownish saprolite occasionally with yellow spots. The texture and color can be

related to intermediate to mafic fine grained volcanic units,. Porphyry Andesite may also be present

as indicated by the more course-grained textural features. A small interbed of mudstone has been

noted between 109 and 110 meters and seems to be overlain by pyroclastic units.. Bedding of

mudstone striking 170o dipping 45o to the west. Evidence of deformation is indicated by the

occurrences of localized boudinated, sheared small quartz veins and strongly foliated fabric between

47 and 55 meters. Shear fabric is oriented 325o dipping at 50 degrees to the east.

The presence of Quartz veining occurs in small amounts, cm in size without any major alteration.

Of the 182 samples previous collected, a total of 18 were reported to contain over 0.1 g/t gold with

the highest values of 0.35 g/t and these are listed in Table 1 below. The “best” values seem to have

been collected within the volcanic portion of the Trench. The veins vary in thickness from one to

several cm in size showing in many cases evidence of ductile-brittle deformation.

TRENCH: TR09

Trench 09 shows a more interesting and diverse character in regards to the geology. The southern

eastern part of the Trench starts within the volcanic unit alternating between fine grained andesite

and porphyry andesite with some intercalations of pyroclastic tuffs.

At 39 meters to north-west, a sharp contact with the sediments can be observed showing evidence of

shear deformation. Contact recorded to be oriented at 210o and shallow dipping at 25

o. The

sediments are primarily graywackes grading to more mudstone units towards NW and are clearly

evident by its dark grayish color showing alternating beds. From 176 meters, lithology changing

again to volcanic until the end with the last 10-15 meters mostly composed of ferruginous massive to

pisolithic clay soil with some presence of duricrust boulders.

Shear and folding deformation structures are very common and can be distinguished at several

intervals. Shear fabric is localized and mostly located at the contact between the different units

occasionally occurring with bleached alteration zones while variation in bedding orientation in

mudstone units indicates folding in the area. Some interesting shear oxidized quartz veins were

intercepted at several intervals in Trench 09.

Of the 148 samples previous collected by author Only 7 samples were reported to contain over 0.1

g/t gold with the highest values of 0.35 g/t and these are listed in Table 1 below. The “best” values

seem to have been collected within the volcanic region of the Trench. The veins varies in thickness

from one to several cm in size showing in many cases evidence of ductile-brittle deformation.

TRENCH: TR027 (Not sure which this is DJL maybe trench 2)

Trench 027 have intercepted the following geological profile:

The presence of mafic intrusions with some intercalations of intermediate volcanics. In between the

mafic intrusion the same folded like feature could also be seen within the mafic intrusion but are

more fine grained to porphyritic texture. On one location, a strong foliated fabric could be seen

between the intrusive and volcanic unit, possibly due to faulting or shearing. Occurrences of

boudinage to slightly brecciated quartz veins are additional evidence to this. Previous assay results

have indicated part of the intrusion shows gold values even though no quartz veining were

intercepted. Dark fine irregular crosscutting bands are though present sometimes with relics

of boxwork of sulfide.

Although several quartz veins were intercepted by channel sampling only 4 samples were reported to

contain over 0.1 g/t gold with the highest values of 0.3 g/t and these are listed in Table 1 below. The

“best” interval seems to have been collected in close proximity to the younger mafic intrusives.
