The program specifically targeted the southeastern parts of the Kalana Exploitation Permit, following on the success of the drill programs conducted within Grid-8 in 2005 and early 2006. The results at the Grid-8 area confirm and extend (up-dip) the mineralized zone discovered in 2005. The results of the Grid-7A area indicate that the mineralized systems in this grid area appear to have more modest grades and widths within 50 metres of surface.
Grid-8 area
Twenty-five holes, inclined at -50 degrees, were drilled within Grid-8 totaling 2,542m. 9 holes to test the near-surface block within the known mineralized section of the Djirila Main Zone; 9 step-out holes along the Djirila Main Zone horizon; 6 holes to test IP geophysical anomalies east of the Djirila Main Zone; and 1 hole to check anomalous gold values obtained in quartz material sampled in an artisanal mining pit situated approximately 1km NE of the Djirila Main Zone.
Six of the nine drill holes testing the near-surface, up-dip block at the Djirila Main Zone returned significant intersections and confirm that gold mineralization continues to surface. The best intersections include: 15.8g/t over 2m from 53-55m, and 10.1g/t over 1m from 59-60m in RC-28; 2.1g/t over 2m from 24-26m and 4.7g/t over 2m from 96-98m in RC-29; 2.2g/t over 1m from 17-18m and 4.6g/t over 1m from 100-101m in RC-31; 4.4g/t over 1m from 88-89m and 4.4g/t over 1m from 96-97m in RC-32; 9.7g/t over 3m from 84-87m and 2.0g/t over 1m from 94-95m in RC-33.
Of the 9 step-out holes, 5 holes returned anomalous intersections above 1g/t (RC-35, RC-36, RC-46, RC-47, RC-48). RC-35 and 36 are located along the SW part of the Djirila Main Zone, RC-47 and RC-48 are located along the NE extension of the Djirila Main Zone and RC-46 is located near an artisanal mining zone located west of the Djirila Main Zone.
None of the six holes drilled to check the IP geophysical anomalies east of Djirila Main Zone encountered mineralization of interest. RC-51 returned only a weak mineralized intersection and did not fully verify the mineralization (i.e., 5.3g/t) found in place within an artisanal pit above the hole.
Grid-7A area
Thirty holes, inclined at -50 degrees, were drilled in Grid-7A totaling 2,525m (RC-52 to RC-81, fig. 2). The holes were located in the Tonda anomalies, to the north, and in the Dabaran West anomalies, to the south. The holes were planned to test various soil anomalies and artisanal workings: 11 holes in Tonda “A” sector (RC-71 to RC-81) and 2 holes in Tonda “D” sector (RC-60 and RC-61) tested the two largest clusters of anomalous gold values of Grid-7A; 7 holes in Tonda “B” sector (RC-64 to RC-70) and 2 holes in Tonda “C” sector (RC-62 and RC-63) tested the smaller soil anomalies on strike with the larger mineralised trends of Tonda “A” and Tonda “D”; and 8 holes in the Dabaran West sector tested a weaker, NNW-trending band of gold anomalism present in the south-central part of Grid-7A.
The results returned for the Grid-7A area (Tonda and Dabaran West anomalies) indicate that the mineralized systems in this grid area appear to have more modest grades and widths in the near-surface environment. The significant and anomalous results for Grid-7A are presented in table 2.
QA-QC entailed adding control samples at the level of 12% of the number of samples, comprising standards (4%), blanks (4%), and duplicates (4%). Six different certified reference material (CRM) standards were used.
The RC drill campaign was supervised in the field by Michel Mercier (a “Qualified Person” in accordance with National Instrument 43-101), who is a consulting geochemist and exploration geologist with more than 20 years of experience in West Africa.
The results have been reported in a press release dated 17 July 2006. The program and the results are described in a document entitled “Technical Report- Kalana Phase IV RC drill programme (Q2, 2006), Kalana Exploitation Permit, Southern Mali, West Africa dated 3 August 2006”.
A geochemistry soil sampling program was completed on two areas of the Kalana Permit during the period February/March 2006. This is the third soil sampling program completed on the Permit. The other 2 programs have been reported in Phase 1 and Phase 11 Technical Reports where 9 gold-in-soil anomalies were identified.
A total of 1,509 soil samples were collected within three grids:
- Grid 10B located east and north of the operating Kalana Mine
- Sector between Grid 5 and Grid 6
- Grid 7B located on the east half of the Dabaran area
In the Kalana Mine area the results show:
- Zone A is characterised by high Au values above the 98th percentile and has produced significant Au-in –soil within 1.0 kilometres of the Kalana Mine. There are at least two drill targets including a possible extension of the Kalana II open pit resource.
- Zone B hosts several significant Au-anomalous zones. In particular a new anomaly (B-2) that encompasses an area of approximately 1,000m by 400m lies to the west of the previously identified Kalanako prospect, and represents a drill target.
- Zone C is host to a very significant orpaillage site (zone B-10 to C-2) with more than 3,500 orpailleurs pits that stretch in a north easterly direction for over 1.5 km.
In the Dabaran area the results show:
- Four main Au anomalies have been identified. Despite the relatively low values the dimensions up to 2.5km in length are important. The pattern of the Au anomalism of the southern clusters is somewhat different to the majority of the Permit. The preferred ENE orientation of the soil anomalism is probably controlled by the large, donut-shaped intrusion that lies immediately to the south.
It is planned to complete an ICP multi-element analysis for a 35 element suite for all samples collected during the 2006 soil sampling program. To date there has been generally good correlation between gold and arsenic on the anomalies identified on the Kalana Permit.
The results have been reported in a Press Release dated 10 July 2006. The program and results are described in a document entitled “Technical Report- Kalana Phase IV 2006 Geochemical Soil Sampling Program, Kalana Exploitation Permit Area, Southern Mali, West Africa dated June 18, 2006”
Diamond Drill Program at Djirila Hill (Grid 8)
Avnel Gold has partially completed the Phase 4 exploration program on the Kalana Permit. The program is scheduled to be complete by Quarter 3, 2006 and includes:
- Diamond drilling at Djirila on Grid 8
- Geochemical soil sampling on Grids 10B and 7B
- RC drilling at Djirila (grid 8) and Grid 7 to follow up gold anomalies
- Ground geophysical (IP) survey on selected areas Grid 8 and Grid 7
The diamond drill program has been completed and results announced in a press release dated April 19, 2006. The objective of the program was to follow up on the initial discovery holes drilled in mid 2005 in Phase 3. The highlights are summarized below:
- The gold mineralisation in the Djirila Main Zone is best developed in DDH-02 (11.14g/t Au over 24m from 68-92m and 4.81g/t Au over 10m from 136-146m), in DDH-06 (14.57g/t Au over 3m from 98-101m), in DDH-11 (19.3g/t Au over 2m from 46-48m, 12.55g/t Au over 19m from 80-99m and 5.72g/t Au over 2m from 120-122m), in DDH-12 (3.04g/t Au over 7m from 92-99m), in DDH-13 (3.74g/t Au over 14m from 98-112m), and in DDH-14 (3.14g/t Au over 3m from 113-116m).
- This mineralised zone has now been traced by diamond core drilling along a NNE strike for more than 225m where it has been found to have a vertical to steep easterly dip.
- The width of the mineralised zone varies from 3 to 50 metres and appears to be associated with a NNE-trending corridor of faulting and silica-sulphide emplacement. The zone of artisanal workings stretches another 150m beyond the present drill program.
- A ground geophysical survey (IP) conducted over the Djirila Hill area has outlined a linear zone marked by both resistivity and chargeability anomalies parallel to the Djirila Main Zone verifying the presence of the quartz vein network and anomalous sulphides that have been found in the core drill program. The continuation of the geophysical anomalies to the north and south of the present DDH locations indicates that the Djirila Main Zone may have additional significant strike length.
Avnel Gold has completed a Technical Report entitled “Kalana Phase IV Exploration Drill Program (2005-2006), Kalana Exploitation Permit Area, Southern Mali, West Africa” dated April 18, 2006. The report is available on the Avnel Gold web site. The report is contained in 3 Volumes covering the interpretation of results, geology, detailed drill logs and quality assurance program. The report was prepared by Michel Mercier (P.Geo, BSc Geology) and Jack Hamilton (BSc Geology). Michel Mercier is a qualified person in terms of the Canadian regulatory instrument NI 43-101. The report was reviewed by Roy Meade (C.Eng, BSc Mining Engineering) who is a qualified person and CEO of Avnel Gold Mining Limited.
Graham Greenway of Snowden Mining Industry Consultants visited the site during the drill program and the Independent Competent Person’s Report is included in the Technical Report. Graham Greenway also provided a review of the results of the quality assurance and control programs According to Snowden Report, the QA/QC procedures adopted by Avnel are comprehensive and suitable for the assessment of quality of drill hole core assay data, which is likely to form the basis for any future resource estimate.
The report has recommended a 5,000m RC drill program in quarter 2, 2006 with the following objectives:
- within the Djirila Main Zone in order to accomplish an appropriate drill hole spacing to facilitate an inferred resource calculation.
- step out holes to test the extention of the Djirila Main Zone north and south
- test the geophysical anomaly identified 450m east of Djirila
- first pass RC program to test the gold anomalies identified on Grid 7B in phase II
