BLACKMANS (MT MAGNET) – MAIDEN RESOURCE & EXPLORATION UPDATE
Highlights
- Maiden Mineral Resource of 490,000t @ 2.5 g/t Au for 39,000oz
- Shallow resource, likely open pit operation, close to Mt Magnet
- Mining study & permitting processes underway
- Additional high-grade drill intersections below current resource including 10m at 15.7 g/t Au
Ramelius Resources Limited (ASX:RMS) is pleased to announce a maiden Mineral Resource estimate for its Blackmans gold deposit, 30km north of Mt Magnet in Western Australia;
Total Mineral Resource is estimated at 490,000 t @ 2.5 g/t Au for 39,000 contained ounces
The new resource estimate was generated following recent RC drilling conducted by Ramelius in December 2014 and February 2015 as well as previous RC drilling carried out by Harmony Gold in 2006. Mineral Resource classification details are shown in Table 1 below.
Initial scoping work suggests a viable open pit operation and more detailed evaluation is now in progress. Ramelius has commenced heritage and environmental work with a view to gaining all required permitting for an open pit mining operation.
Subsequent deeper exploration drilling, carried out in May 2015 below the resource estimate envelope, continues to return high grade gold intersections including:
- 10m at 15.76 g/t Au from 104m in BMRC0053, and
- 10m at 3.81 g/t Au from 63m in BMRC0048
Ramelius Chief Executive, Mark Zeptner today said:
"The Blackmans Project has the potential to provide a valuable source of oxide ore for the Mt Magnet operation. Evaluation and permitting work on the project is already underway with a target of adding Blackmans to the life-of-mine plan in the 2016 calendar year".
"The overall production profile published by Ramelius does not currently include any contribution from Blackmans and the fact that we have some excellent intersections that currently sit outside the Mineral Resource highlights the potential positive impact that this project may have on the Company's future gold production".
Blackmans Gold Project
Blackmans is located 30km north of Mt Magnet, relatively close to the Company's Checker processing facility on the outskirts of Mt Magnet itself.

Figure 1: Blackmans Project Location
The Company secured 100% ownership of the Blackmans tenement (ML58/222) in late 2014 and subsequently embarked on a programme of RC drilling in December 2014. Drilling was highly encouraging with numerous economic intercepts returned from 18 holes drilled. A further 29 infill RC holes were completed in February 2015, with the aim of infilling the deposit to a nominal 10m by 25m drill spacing and generating a resource estimate (see Figure 2). Prior to these programs, 45 RC holes were completed by Harmony Gold in 2006.
Gold mineralisation at Blackmans extends over at least 350m strike and is associated with a number of subparallel, steeply west dipping quartz-sulphide lodes developed within high Magnesium (Mg) basalt host rocks (see Figure 3). Lodes are generally 2-5m wide, from 10-20m below surface and vary between 60 and 300m in strike length. The lodes are overlain by transported laterite of 8-15m thickness, which contains a flat lying 2-5m thick, supergene enriched, gold blanket near the base of the laterite.
Mineral Resource
The Mineral Resource was initially generated in April 2015 and more recently finalised following independent auditing and is summarised below:
| Table 1: Blackmans Mineral Resource (>1.0g/t) | ||||
|---|---|---|---|---|
| -- | ----------------------------------------------- | -- | -- | -- |
| Resource Category | Tonnes | Grade | Au (oz) |
|---|---|---|---|
| Indicated | 361,000 | 2.6 | 30,000 |
| Inferred | 129,000 | 2.3 | 9,000 |
| Total | 490,000 | 2.5 | 39,000 |
Note: Figures rounded to nearest 10,000 tonnes, 0.1g/t and 1,000 ounces. Rounding errors may occur.
Within the Indicated Resource total tabled above, the shallow laterite gold domain contains 97,900 t @ 1.7g/t for 5,400oz.
Mineral Resource Commentary
The resource was generated from 92 RC holes. Drillhole density is typically 10m x 25m.
Interpretation was carried out on 25m spaced sections utilising the geological interpretation described above and a nominal 0.5g/t lower cut-off. A minimum 2m downhole intercept with was used and sub-grade material was included to maintain lode width & shape continuity. RC sub-samples were assayed by Fire Assay at a Perth commercial laboratory. Appropriate QAQC samples accompanied primary sample batches.
Samples were grouped by domain, composited to 1m intervals, top-cut and gold was estimated using Inverse Distance and anisotropic searches. Resource classification was applied based on drillhole density and interpreted mineralisation continuity. Resources were reported above a 1.0 g/t lower cut-off, which is near the estimated economic cut-off. Resources have been generated for evaluation by open-pit mining methods and have a maximum depth of 130m.
Oxidation extends to 80m below surface and density values are assumed based on Mt Magnet values and experience. No metallurgical test work or environmental surveys have yet been conducted.
Detailed information is given in JORC Table 1 attached below.
The resource model and report was reviewed by an independent external consultant and no major issues were identified.
Deeper Exploration Drilling
Ramelius completed six deeper exploration RC holes (BMRC0048 to BMRC0053) for an aggregate 924m below the shallow resource model. The holes were designed to scope the predicted plunge of the higher grade Eastern Lode below 100m depth but demonstrated strong dip continuity persists below the shallow supergene anomalous Western Lode. The very high grade fresh rock intersection of 10m at 15.76 g/t Au within the Western Lode, is in a position previously believed to have been closed off by shallower drilling (Figures 3 and 4). The intersection highlights good depth continuity may continue within the mineralised system.
The deep oxidation had hampered geological interpretations within the top 80m of the resource but the recent deeper drilling has confirmed a strong geological control constrains the mineralisation within the lodes. The lodes are hosted within a 50m thick package of high Mg basalts, bound by ultramafic rocks on both the footwall and hangingwall sides. Steep west dipping interflow shale/sediment horizons further west provide good, dip continuity to support the lode interpretations. The Eastern Lode persists at depth within the high Mg basalt rocks (with a shallow northerly plunge – analogous to the Western Lode – see Figure 5) but the grade and thickness of the deeper intersections suggest the mineralisation is discontinuous.
Further deeper exploration drilling will focus on targeting the higher grade Western Lode intersections at depth.

Attachment 1: Significant (>0.50 g/t Au) RC drilling results within the Blackmans Gold Project – Mount Magnet WA
Reported significant gold assay intersections (using a 0.50 g/t Au lower cut) are reported over a minimum down hole interval of 1m at plus 0.50 g/t gold. They may contain up to 2m of internal dilution. Gold determination was by Fire Assay, using 50gm charges with AAS finishes and a lower limit of detection of 0.01 g/t Au. NSR denotes no significant results. True widths are estimated to represent 65% of the reported down hole intersections unless noted. Coordinates are MGA94-Z50.
