1 Black Ridge Mining NL ( BRD ) Announcement 10/03/2015 MMI Soil Geochemistry Results, Unaly Hill Project (E57/420) HIGHLIGHTS Results from recently completed Mobile Metal Ion ( MMI ) have yield significantly anomalous multi-element soil results Nickel anomalism up to 44.5 times the geochemical background Gold anomalies up to 43 times the geochemical background Several coincident vanadium, titanium, and iron anomalies situated on trends untested by previous drilling by Black Ridge Mining Ltd Highlights potential to yield further V, Ti, Fe mineralisation as well as gold and base metal mineralisation. Black Ridge Mining Limited (ASX:BRD) is pleased to announce that a recently completed 303 sample Mobile Metal Ion ( MMI ) soil geochemical sampling program has returned significant gold and base metal anomalism. Anomalies of coincident vanadium, titanium, and iron were also recognized in areas away from the previously announced Indicated Mineral Resource. (BRD ASX Announcement 21/11/2011) The Unaly Hill Project (E57/420) is situated some 500km north east of Perth, Western Australia and is a single tenement covering over 13 kilometres of the strike length of the regionally significant Youanmi Fault. This structure represents the boundary between the Murchison Province and the Southern Cross Province of the Youanmi Terrane of the Yilgarn Craton. Immediately west of the Fault is the Atley Igneous Complex ( AIC ) The aim of the soils program was to test for anomalous base metals, precious metals and vanadium/titanium/iron within the AIC, a layered mafic/ultramafic intrusion. MMI geochemistry was used for its sensitivity over other conventional geochemical methods in environments dominated by a transported regolith. Historic surveys in this area have included broad conventional soil sampling and RAB drilling. These programs have largely focused on gold mineralisation, given the close proximity to the Youanmi Fault, its associated secondary structures and the endowment of gold deposits in the local region from Sandstone to Youanmi Gold Mine. Historic RAB drilling within the survey area was assayed for gold only, however examination of down-hole geological logs revealed several intersections of ultramafic lithologies and minerals assemblages identified from rock-chips, and later verified in the field at old drill sites. A number of pyroxenitic units within the AIC were therefore interpreted to occur and were targeted as host units for nickel sulphide mineralisation.

2 The soil survey was also used to test for further vanadium, titanium, and iron occurrences outside the known Inferred Mineral Resource delineated from reverse circulation drilling by BRD and previous explorers. Precious metals were also included in the suite of elements analysed as the project is considered to have significant potential for gold mineralisation. The MMI survey involved the collection of 303 samples from a total of 11 east-west traverses with an equidistant spacing of 500m. Samples taken along the traverses were spaced at 75m. Strict adherence to SGS MMI sampling protocols was observed. Approximately 250g to 300g of the -5mm fraction was collected from a depth of 15cm to 25cm. The MMI soil sampling and analytical method has been commercially developed to detect buried mineralisation beneath regolith and/or transported cover. Results are given in parts per billion (ppb) range with the lower (25 th ) quartile used as the statistical background and element anomalies calculated as a response ratio (RR) relative to the background. Samples were sent to SGS laboratories in Perth for analysis of a suite of 19 elements which included Ag, Al, As, Au, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Pd, Pt, S, Ti, V, and Zn. RESULTS Figure 1 Planned MMI Program at Unaly Hill Project Response ratios were calculated for each of the 19 elements. A response ratio measures the degree of enrichment in each element per sample, and is calculated by comparing each result per element per sample with the calculated background in that element. Anomalies and targets warranting further investigation were grouped into base metal (nickel), gold, or vanadium/titanium/iron targets. Black Ridge Mining NL Page 2

3 Nickel In the north eastern area within the survey is a significant nickel soil anomaly defined by the MMI sampling with peak anomalies up to a response ration of 44.5 times the background. Cobalt correlated strongly, along with cadmium, magnesium and chromium. This is also coincident with several ultramafic units recorded in historic drill logs and represents a significant target warranting further investigation. Anomalism is interpreted to extend for over 1km of strike and up to 300m at its widest point. The anomaly is also open to the north. Further to the west and south are numerous moderate to weak anomalies with strong correlations to cadmium, cobalt, and magnesium. These are interpreted to represent several pyroxenite units with the exception of a single point anomaly which recorded at mN and mE (MGA94 zone 50) where magnesium peaked at a RR of 48.7, sulphur at 27.3 RR, cadmium at 28.0 RR, cobalt at 11.2 RR and nickel at 10.8 RR. This anomaly possibly overlies a higher magnesium unit where cumulate textures may have formed and peridotite lithologies may occur. Gold Figure 2 Unaly Hill MMI Nickel Anomalies on GSWA Geology and Magnetic Image The MMI survey delineated a of well attenuated gold anomaly in an area adjacent to the nickel anomaly in the north east corner of the sample grid. A peak gold response ratio of 43 was recorded and coincident with a sulphur response ratio of The gold anomaly is robust and significant occurring with a north east strike length in excess of 1km and a core over 300m in width. The gold is also spatially correlated with magnesium, Black Ridge Mining NL Page 3

4 silver, and cadmium, as well as weaker copper anomalism. This anomaly is in close proximity to the Youanmi Fault structure and the strike direction of the anomaly may represent a mineralised secondary structural splay. This anomaly has not been effectively tested by historic RAB drill traverses and represents a significant target which will be investigated further. The anomaly, similar to the nickel anomaly, is open to the north, northeast. Figure 3 MMI Gold Anomalies on GSWA Geology and Magnetic Image Vanadium, Titanium, and Iron From the MMI sampling it was evident that several other vanadiferous titanomagnetite units occur in areas untested by the RC drilling that defined the Inferred Mineral Resource. There was a very strong correlation between vanadium, titanium, and iron in several localities away from the most prominent magnetic high where the known mineralisation occurs. This indicates there are a number of prospective targets within the southern portion of E57/420 delineated by MMI sampling that are likely to yield further vanadium, titanium, and iron mineralised drilling intersections which may potentially add further volume to the existing resource.

5 Figure 4 Unaly MMI V, Ti, and Fe anomalies on GSWA Geology and Magnetic Image The MMI survey carried out at the Unaly Hill Project has been successful in generating a number of high quality targets requiring follow-up investigation with further infill sampling, geophysical surveying and drilling. The southern portion of the tenement, concealed by transported alluvium and colluvium, had been previously shown by drilling to be prospective for V, Ti, and Fe, however the recent program has improved on this. The MMI survey has also highlighted the potential remains for E57/420 to yield significant precious and base metal mineralisation.

6 Appendix 1 - JORC Code 2012 Edition Table 1 Section 1: Sampling Techniques and data Criteria JORC Code Explanation Commentary Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gammas nodes, or hand held XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. The Unaly Hill Project is sampled on a nominal 500m by 75m grid spacing. A total of 303 samples were collected at a depth of between 10cm and 25cm in accordance with sampling protocols stipulated by SGS Laboratories. Sampling Techniques Include reference to the measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where 'Industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1m samples from which 3kg was pulverised to produce a 30g charge for fire assay') In other cases more explanation may be required, such as where there is course gold that has inherent sampling problems. Unusual commodities mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. The sample locations are picked up by handheld GPS. Samples were logged for landform, and sample contamination. Sampling was carried out under consultant Unearthed Elements standard protocols and QAQC procedures as per industry best practise. All samples were sieved through -5mm plastic sieve in accordance with SGS MMI sampling protocols. QAQC protocols include that laboratory analysis of at least 10-20% of all samples. Samples were sent to SGS Laboratories in Perth, where they were prepared for analysis by SGS's propriety MMI analytical technique. Drilling techniques Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face sampling bit or other type, whether core is oriented and if so, by what method, etc.) Drill sample recovery Logging Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. Whether core and chip samples have been geologically and geotechnical logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc.) photography The total length and percentage of the relevant intersections logged. Soil samples were not logged Soil samples were not logged Soil samples were not logged Black Ridge Mining NL Page 6

7 Criteria JORC Code Explanation Commentary Sub-sampling techniques and sample preparation If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representatively of samples... All soil samples were prepared for analysis in the field being sieved to -5mm, bagged, numbered and sorted. AtSGS Laboratories in Perth samples were sorted and dried, thence pulverised with 10-20% of the sample (approx. 25g) being analysed. No quality control procedures undertaken to determine sample representivity. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling Whether sample sizes are appropriate to the grain size of the material being sampled. The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. No duplicate samples were collected No orientation soil surveys were completed prior to the program. Samples were taken in the field and analysed in the laboratory in accordance with best practise industry standard for the medium sampled in the particular environment and is considered appropriate geochemical test work. Quality of assay data and laboratory tests For geophysical tools, spectrometers, handheld XRF instruments, etc. the parameters used in determining the analysis including instrument make and model, reading times, calibration factors applied and their derivation, etc. No XRF, spectrometers or similar instruments were used. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. No standards or blanks were used in this program The verification of significant intersections by either independent or alternative company personnel. There has been no external check assaying undertaken on the soil samples. The use of twinned holes.. Verification of sampling and assaying Documentation of primary data, data entry procedures, data verifications, data storage (physical and electronic) protocols. Location and sampling data were collected by experienced field geologist and entered into Excel spread sheets. Location and analysis data are then collated into a single Excel spread sheet. Data is stored on servers in the Company s head office and consultants server, with regular backups and archival copies of the database made. Discuss any adjustment to assay data No adjustments are made to the data. Black Ridge Mining NL Page 7

8 Criteria JORC Code Explanation Commentary Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Location data for soil sampling points was recorded by handheld GPS (+3m accuracy). Location data is downloaded from hand-held GPS using appropriate software. Location of Data Points Specification of the grid system used. Coordinate system is UTM Zone 50 and datum is GDA94 Quality and adequacy of topographic control Topographic data was obtained from public download of the Youanmi 1:250,000 scale GSWA geologic map sheet. Data spacing for reporting of Exploration Results Soil samples were collected on a 500m x 75m nominal grid layout. Data spacing and distribution Whether the data spacing and distributions sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied Sample spacing was deemed appropriate for identifying geochemical anomalies but could not be used to establish geological and grade continuity. It would not be appropriate to use this information in a Mineral Resource or Ore Reserve estimation capacity No sample compositing has been applied. Orientation of data in relation to geological structure Sample security Audits or reviews Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. The measures taken to ensure sample security The results of any audits or reviews of sampling techniques and data Known mineralisation of V, Ti, and Fe occurs within the sample area and is oriented N-S to NE-SW. The Youanmi Fault runs through the tenement in a NNE orientation. Sampling was carried out on east-west traverses being close to perpendicular to mineralisation to achieve reletively unbiased sampling form these structural orientations abd to cross-cut stratigraphy. Samples were collected and prepared in the field by an experienced geological consultant To date there has not been an audit of sampling techniques and data. Black Ridge Mining NL Page 8
