RAB Drilling Results Confirm Bedrock Gold Anomalism at Naujombo and Kishugu

 

HIGHLIGHTS

 

  • Limited reconnaissance drilling confirms strong gold anomalism reported over 9.5km of strike at Naujombo and over 5.5km of strike at Kishugu

 

  • Significant zones of gold anomalism within bedrock on each drilling line

 

  • Results indicate that both Naujombo and Kishugu are large gold systems

 

  • Targets identified for follow up drilling

 

 



West Perth WA (FSCwire) - Indiana Resources Limited (ASX: IDA) (‘Indiana’ or the ‘Company’) is pleased to advise that the recently completed Rotary Air Blast (‘RAB’) drilling program at Naujombo and Kishugu, comprising 136 holes for 3,398m intersected strong anomalous gold in bedrock on each line of drilling.

 

Indiana’s Managing Director Campbell Baird commented:

 

“The first round of drilling at Naujombo and Kishugu was designed as a reconnaissance program across the strong surface soil gold anomalies that have been previously identified. The drilling program sought to establish whether the surface gold was present in the bedrock. It is particularly encouraging that along each line of drilling over a strike of 9.5 kilometers and 5.5 kilometres for Naujombo and Kishugu respectively, we have intersected zones of anomalous gold within the bedrock.  In achieving that aim, this drilling program has laid a strong platform for follow up drilling and further field programs, with work on a second stage drilling program and field work on newly identified targets already under way. This is an outstanding first step in unlocking the gold systems at Naujombo and Kishugu.”

 

Objectives of drilling program

 

There is no outcrop in the area and the resulting deficit of geological information, both lithology and structure, due to ubiquitous transported cover, presents a challenge at Naujombo and Kishugu. The systems have been identified through surface soils and gradient array induced polarisation (‘GAIP’) surveys. A key objective of the drilling was to not only identify gold mineralisation in the bedrock, but also to understand the subsurface geology that is potentially hosting the mineralisation and to determine the most suitable exploration and targeting techniques for future programs.

 

Drilling results

 

The levels of anomalism found in the bedrock reach a maximum of 1g/t over 3m, but are typically in the range of 20-200ppb.  The regional geology has a background gold value of 2 ppb and any gold value of greater than 20ppb is significant when compared to background.

 

This means that the samples represent rocks that have been altered and are indicative of a gold mineralised system, further supported by anomalous levels of elements such as arsenic, bismuth and silver.  Further, on the scale of testing undertaken, these results indicate that Naujombo and Kishugu are very large gold systems and have the capacity to host significant mineralisation.

 

The quantity of gold in the system is substantial even at these relatively low levels. The distribution of gold is expected to be distributed unevenly within these systems and the probability is high that the thickest mineralisation and highest grades have not been intersected. The task now is to assimilate all the data and determine where along these large systems we need to test, or vector towards, in order to improve the chances of intersecting plus 1g/t mineralisation.

 

Naujombo

 

Drilling found gold anomalism in every line drilled across the 9.5km anomaly, indicating that Naujombo is a large system, with the bedrock mineralised across its entire length (see Figure 1). The results are from nine wide spaced RAB lines drilled over a strike of 9.5km along the Naujombo anomaly (see Figure 1), with the locations of the targets based on gold and arsenic anomalism in surface soils and a recently completed GAIP survey.

 

The drilling also identified that the subsurface bedrock is most likely of a sedimentary nature, which assists in understanding the type of gold deposits that may be targeted.

Drilling was carried out on an 80m spacing on lines greater than one kilometer apart and drilled to hard rock refusal. As this was the first drilling program for gold undertaken in the area, there was limited experience as to what indicates gold mineralization. Some of the lines drilled did show wide zones of alteration that may be indicative of gold mineralizing events. It is acknowledged that as a result of this, a number of drill lines may not have extended far enough (see Figure 2: Section 12240mN).

 

In Section 12240mN, anomalous gold was intersected continuously from surface to the bottom of the hole (24m). This was the last hole drilled on the section, being a section between the largest geochemical and geophysical anomalies. Clearly this line can be extended to the north-west and has been identified as an area for priority follow up drilling.

The anomalous zone identified on Section 12240mN looks to be in the middle of a magnetic high (see Figure 3) with drilled section lines on either side intersecting anomalous gold, suggesting a potential strike length of more than 2.5km.

Kishugu

 

Drilling at Kishugu found gold anomalism on every line drilled along the 5.5 km anomaly, inferring that the bedrock is potentially mineralised along its entire length. Like Naujombo, the drilling also identified that the subsurface bedrock is most likely of a sedimentary nature.

 

The results received are from four widely spaced, reconnaissance RAB lines drilled over a strike of 4.5km over the 5.5km long Kishugu gold anomaly (see Figure 4), where drilling intersected strong anomalous gold in bedrock on each line.

Drilling at Kishugu was either on a limited strike with top to tail drill hole coverage or on 100m hole spacings along existing tracks. Similar to Naujombo, it is acknowledged that on a number of lines, drill lines were not wide enough (see Figure 5: Section 14700mN). In section 14700mN, anomalous gold was intersected continuously from surface to the bottom of the five north-western holes and this anomalism is currently interpreted to be at least 120m wide. Clearly there is scope to extend the section to the north-west and this has been identified as an area for priority follow up drilling.

Extensive anomalism at Naujombo and Kishugu

 

Naujombo

 

The extent of the gold anomalism in each of the section lines indicates that the mineralisation at Naujombo is a large system. An example of the extent of the gold anomalism intersected is found in Section 16720mN, which is 4.5km along strike from Section 12240mN. The drilling on this section intersected a number of zones of anomalous gold and when interpreted along with the surface soil sampling, a zone of interest of over 150m wide has been interpreted for this section (see Figure 6).

Kishugu

 

The most outstanding result achieved, and a demonstration of the extent of the gold anomalism intersected at Kishugu, was along the oblique Section drilled at the far south of the Kishugu anomaly (see Figure 7), where an intersection of 3m @1.07 g/t was recorded in hole NRB16-0075. This section is 3.5km to the south from the far northern anomalous section 14700mN and drilling on this section intersected a very wide of zone of anomalous gold and when interpreted along with the surface soil sampling, is a zone of interest of over 150m wide.

 

The drilling of this section was along a track that ran in an oblique north-west direction as opposed to all other section lines that were drilled in a north-east direction. The reason for this direction of drilling was that an existing track passed directly over two strong gold in soil anomalies and in order to save on cost and time and avoid unnecessary ground disturbance, this track was utilised for drilling.

Next steps

 

The results from the RAB drilling program are particularly encouraging, with gold in the bedrock having been identified over 9.5 km and 5.5km of strike at Naujombo and Kishugu respectively.

 

The Company has received a substantial amount of data from this program and is continuing the process of working through the information to enhance its understanding of the Naujombo and Kishugu Prospects and to inform future exploration. A preliminary review of the results, together with the existing extensive geochemical and geophysical datasets, has identified a number of new standout drilling targets and areas within the anomalies for follow up field work. The testing will target both direct tests underneath identified anomalism as well as vectoring along strike towards zones of higher gold tenor.

 

Planning for a second stage of drilling at Naujombo and Kishugu is under way and with Naujombo accessible by an all-weather road, the end of year wet season is not expected to be a constraint to undertaking this next stage of exploration at Naujombo.

Mr. Perrot has verified the data underlying the information contained in this announcement and approves and consents to the inclusion of the data in the form and context in which it appears.

 

Naujombo and Kishugu Gold Prospects

 

The scale and level of gold anomalism at Naujombo is similar to that of Kishugu, with the two anomalies located 35km from one another, in a very similar structural setting. Figure 8 illustrates that Naujombo and Kishugu are associated with the same structural corridor and are located on the margin of similar circular magnetic features. The potential exists to identify a significant gold camp should the anomalies confirm the presence of economic gold mineralisation. Both anomalies also exhibit very similar multi-element signatures typical of primary gold mineralisation (arsenic, bismuth and silver).

APPENDIX B. JORC 2012 Table 1 Reporting

 

Section 1. Sampling Techniques and Data

Criteria

Explanation

Sampling techniques

  • Samples were composited to 4m and sent for PGM-ICP23 analyses (Fire Assay). All samples were submitted for analysis.
  • Grade standards (Certified Reference Materials – CRM’s) and field duplicate samples were used to monitor analytical accuracy and sampling precision.
  • Sampling is guided by Indiana Resources’ standard operating and QA/QC procedures.
  • RAB chips are geologically logged and sampled to geological contacts.
  • The 1m bulk samples were sampled with a scoop to generate 4m composite samples of approximately 3kg, or variable 1m to 3m (composite) samples at end-of-hole. An additional 1m EOH multi-element sample was taken.
  • Sample piles are routinely photographed.

Drilling techniques

  • RAB Drilling was carried out using a 4 ½ blade bit to refusal at the fresh rock interface.  Drilling was undertaken by Mitchell Drilling using a Schramm 450 drill rig mounted on a truck.

Drill sample recovery

  • Samples were mainly dry with some rare damp or wet samples. RAB drill recoveries were visually estimated as a semi-quantitative range and recorded in the sample sheet. Recoveries were excellent (>90%), with good recoveries recorded throughout the holes.

Logging

  • Geological logging of all RAB holes captured various qualitative and quantitative parameters such as mineralogy, colour, and texture and sample quality.
  • Logging data is collected via ruggedised laptops. The data is subsequently downloaded into a dedicated Datashed database for storage, hosted by a database consultancy.
  • All RAB holes have been geologically logged both qualitative and quantitative in nature and captures downhole depth, colour, lithology, texture, mineralogy, mineralisation, alteration and other features of the samples.
  • RAB sampling is not appropriate for mineral resource estimation and is considered a qualitative sampling technique.

Sub-sampling techniques and sample preparation

  • RAB composite samples were collected with a sample scoop.
  • The samples were recorded as dry, damp or wet. Sample duplicates were obtained by repeating the composite sampling process.
 

 

APPENDIX B. JORC 2012 Table 1 Reporting (cont.)

 

Section 1. Sampling Techniques and Data

Criteria

Explanation

Quality of assay data and laboratory tests

  • All samples were submitted to ALS for both the sample preparation and analytical assay.
  • Samples were sent to the ALS laboratory in Mwanza (Tanzania) for sample preparation. Samples are crushed so that >70% passes -2mm and then pulverised so that >85% passes -75 microns.
  • For all samples a split of the sample are analysed using a lead oxide collection fire assay and ICP-MS finish (ALS Minerals Codes PGM-ICP23).
  • Every ‘end of hole’ sample was analysed using a complete sample characterisation package (CCP-PKG01). This package combines the whole rock package ME-ICP06 plus carbon and sulfur by combustion furnace (ME-IR08) to quantify the major elements in a sample. Trace elements including the full rare earth element suites are reported from three digestions with either ICP-AES or ICP-MS finish: a lithium borate fusion for the resistive elements (ME-MS81), a four acid digestion for the base metals (ME-4ACD81) and an aqua regia digestion for the volatile gold related trace elements (ME-MS42).
  • QC insertion rates will be every 20th sample (1 standard, 1 blank, 1 site duplicate).
  • Laboratory duplicates and standards were also used as quality control measures at different sub-sampling stages.

Verification of sampling and assaying

  • Senior Indiana Resources geological personnel supervise the sampling, and alternative personnel verified the sampling locations.
  • Assay data is loaded directly into the Datashed database which is hosted by and managed by an external database consultancy.
  • Below detection limit values (negatives) have been replaced by background values for each element.

Location of data points

  • Drillhole collars have been surveyed using a Differential GPS with an accuracy of <5 cm at the end of the program.
  • Collar surveys are validated against planned coordinates and the topographic surface.
  • The primary grid used is UTM WGS84 Zone 37 South datum and projection.
  • A local grid origin 439,750 mE 8,910,700 mN with a baseline oriented 045 has also been used for planning and reporting purposes.

Data spacing and distribution

  • This program is the first drilling conducted in the area. A proportion of the drilling will be exploratory with spacing dictated by the location of targets interpreted from soil geochemistry.
  • The spacing drilling is mainly on 80 m drill spacing with line spacing being variable so as to test the majority of the geochemical anomaly.

Orientation of data in relation to geological structure

  • The majority of holes have been drilled vertically.
  • A limited number of holes have been orientated towards 135 so as to be able intersect observed alteration in a perpendicular manner.

Sample security

  • The samples are packed at the drill site and sealed prior to daily transport to the local field office which has 24 hour security prior to transport by locked commercial truck carrier to ALS Mwanza. The laboratory (ALS) ships the sealed samples after preparation, to Johannesburg in South Africa.

Audits or reviews

  • No audits or reviews have been conducted on sampling techniques to date.
 

 

APPENDIX B. JORC 2012 Table 1 Reporting (cont.)

Section 2. Reporting of Exploration Results

Criteria

Explanation

Mineral tenement and land tenure status

  • The exploration results reported in this announcement are from work carried out on granted prospecting licence 5977/2009 which is owned by Ngwena Limited, a subsidiary of Indiana Resources, prospecting licence 9944/2014 which is owned by Anga Resources Limited, a subsidiary of Indiana Resources and prospecting licence 6635/2010 which is owned by Warthog Resources Limited, a subsidiary of Indiana Resources.
  • The prospecting licences PL 5977/2009, PL 9944/2014 and PL 6635/2010 are in good standing.
  • The tenements are the subject of a joint venture agreement with MMG Exploration Holdings Limited which holds an interest in the Nachingwea Property of approximately 15%.

Exploration done by other parties

  • Exploration has been performed by an incorporated subsidiary company of Indiana Resources, Ngwena Limited.
  • Stream sediment surveys carried out historically by BHP were assayed for the commodity referred to in the announcements and was used to identify this target.

Geology

  • The regional geology is thought to comprise late Proterozoic Mozambique mobile belt lithologies consisting of mafic to felsic gneisses interlayered with amphibolites and metasedimentary rocks.

Drill hole information

  • The drillhole information is supplied in Section 1 and the location of the drillhole collars is shown in the accompanying release (Appendix A).
  • No material information has been deliberately excluded.

Data aggregation methods

  • Significant intercepts are reported based on a 20ppb cut-off with a minimum length of 1 m which has an allowable maximum 4m of internal low grade material. All significant intercepts are generated using Datashed software automated grade compositing function.

Relationship between mineralisation widths and intercept lengths

  • Due to the exploratory nature of the drilling the assessment of geometry of the mineralisation is ongoing.
  • At present all the reported lengths are ‘down-hole’.

Diagrams

  • A diagram showing the location of the drillhole collars is included in this announcement.

Balanced reporting

  • All reported visual estimate intervals are downhole intervals from drilling aimed at being as perpendicular to mineralisation as practical.

Other substantive exploration data

  • All other meaningful exploration data concerning the Naujombo and Kishugu Gold Prospects has been previously reported to the ASX.

Further work

  • Refer to the announcement.
