Ndjole Licence: North East Target - Trench Sample Assays and Mineralogy Test Work

 

David Underwood, Vice President Exploration of BHK Mining Corp. (“BHK” or the “Company”) is pleased to announce that BHK has completed a trench sampling exercise to test the manganese content and mineralogy of the North East Target of BHK’s Ndjole Licence in Gabon. The XRF results from Trench NDTR001 returned 11 metres at 36.1% Mn including 4 metres at 50.24 % Mn (between samples L09306 to L09309). See Table 1 below. The high grade portion has a low iron content of less than 7% Fe.

 

Trench Sampling and Assay
A single trench was excavated at the North East Target to evaluate the supergene enriched portion of the primary manganese mineralization intersected in drill holes NDDD0028, 35 and 40. The trench was approximately 2 metres wide and 11 metres in length although the mineralization was open both to the southeast and the northwest. The trench was excavated perpendicular to strike into the weathered rock which is visible at a depth varying between 1.5 and 3 metres.

A continuous channel sample was collected using a geological hammer along the side wall and floor depending on exposure. The rock chips from the channel were collected at 1m intervals in a plastic bag and submitted to ALS Chemex of Johannesburg, South Africa for XRF analysis. The results from this analysis are presented in Table 1.

Mineralogical Test Work
Sub-samples from two metallurgical bulk samples (results pending) were submitted to Microanalysis of Perth, Australia for mineralogical testing by XRD. Two additional samples were sent to confirm the mineralogy of the manganese carbonate and oxidized manganese carbonate zones – see Table 2.

BHK_Ndjole07 NDMin01 NDDD0040: 20 -48m Primary Mn Head Feed - Bulk sample sent to Nagrom
BHK_Ndjole07 NDMin02 NDDD0040: 20 -48m Primary Mn +1mm 3.8SG Bulk sample sent to Nagrom

BHK_Ndjole15 NDMin05 NDDD0046: 42m Primary Mn zone - check sample

Samples NDMin01, 02 and 05: These samples are from low grade primary manganese mineralization which was intersected in drill holes NDDD0040 and NDDD0028. The primary manganese mineral present is manganese carbonate – rhodocrosite (MnCO3). The gangue mineral species in this sample are quartz, siderite (Fe(CO3)) and muscovite. Manganese carbonate is a highly sought after direct feed ore if it can be mined at a grade of 30% Mn.

Sample NDMin04: This is from the oxidized zone of the primary manganese mineralization. The primary carbonate is oxidized and the manganese forms various oxide species. In this sample the dominant manganese oxides are cryptomelane (K(Mn8016)) and pyrolusite (MnO2). The gangue minerals are dominantly illite, quartz and muscovite.

Sample NDMin03: This is from the high grade supergene manganese in Trench NDTR01. The main manganese bearing mineral is nsutite (Mn(O,OH)2), with lesser cryptomelane (K(Mn8016)) and other manganese oxides and hydroxides. Gangue minerals present are gibbsite, goethite, muscovite and quartz.

David Underwood commented as follows: “The style of mineralization at Ndjole appears to be similar to the Moanda ore body in Franceville, Gabon. At Moanda, the parent rock is also an organic-rich black shale, which contains manganese carbonate as well as quartz, pyrite and illite. The supergene portion of this world class ore body is mined where it is exposed under the manganese poor (iron-rich) laterite”.

Methodology and Quality Control

 

Procedure for Trench Channel Sampling
Collection of Samples: Continuous channel samples were collected from the sidewall and footwall of Trench NDTR001. The channel was cut using a geological hammer and mallet at a constant thickness. The channel samples were bagged at 1m intervals. The weathering and outcrop of the supergene material varies along the length of the trench and there is dilution of the high grade material with soil and highly weathered material. The trench is orientated on azimuth 130 and the northwest start point and length is recorded using a GPS. All locations were recorded in UTM Zone 32S, WGS-84.

Preparation: Login of samples into the ALS Chemex tracking system, weighing, drying fine crushing of entire sample to 70% -2mm, split off 250g and pulverise split to better than 85% passing 75 microns.

Analysis: Analysis at ALS Chemex of Manganese ore samples by fused disc / XRF. Method Precision: ±5%. Samples were analysed for Al2O3, BaO, CaO, Cr2O, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SO3, SiO2, TiO2, V2O5 and LOI1000.

Quality Control: Manganese standards and blanks were inserted into the sample batch.

 

Procedure for Mineralogical Analysis by XRD
Mineralogical samples were submitted to Microanalysis in Perth, Australia. The procedure is as follows:

A representative sub –sample was removed and lightly ground such that 90% was passing 20 µm. Grinding to this size helps eliminate preferred orientation. Only crystalline material present in the sample will give peaks in the XRD scan. Amorphous (non-crystalline) material will add to the background. The search match software used is Eva 3.1. An up-to-date ICDD card set was used. The X-ray source is cobalt radiation. No standards are used in the quantification process.

The concentrations are calculated using the peak area integration method where the area of the 100% peak for each mineral phase is summed and the relative percentages of each phase calculated based on the relative contribution to the sum. This method allows for some attention to be paid to preferred orientation but is limited in considering substitution and lattice strain.

The ICDD match probability is reported as an indication as to how well the peak positions and relative intensities for the sample matched those in the published literature (www.icdd.org) for that particular compound.
