Helio Increases Gold Grade of and Confidence in Mineral Resources at its SMP Gold Project, Tanzania

March 26, 2015
Specific Focus on Higher-Grade Opportunities

Vancouver, March 26, 2015

Helio Resource Corp (TSX-V: HRC), (“Helio” or the “Company”) is pleased to report that it has received an updated NI43-101 compliant Mineral Resource Estimate for its SMP Gold Project, Tanzania, from Snowden Mining Industry Consultants (“Snowden”).


  • The total Indicated Resource is 7.5 million tonnes (“Mt”) grading 2.4 grams per tonne (“g/t”) gold (Au) for 590,000 ounces (oz) Au contained.
  • This can be broken down into 5.9 Mt grading 1.8 g/t Au for 332,000 oz inside a pit constrained shell at US$1,400/oz gold price and 1.6 Mt grading 4.9 g/t for 258,000 ounces of potentially underground mineable material (see Table 2 below).
  • The total Inferred Resource is 0.56 Mt at 2.5 g/t Au containing 45,000 oz Au in the same pit constrained shell and underground configurations.
  • The higher-grade underground resource bodies are all open at depth.
  • The new high-grade zones at Gap encourage further follow-up, especially the western shoot, which returned an intercept of 4m grading 30 g/t Au (see news release dated January 29, 2015).

Mr. Richard Williams, CEO of the Company, commented: “The SMP Mineral Resource is now classified almost entirely as Indicated, which gives us much greater confidence in the quality of the resource estimation and puts us in the position to advance the project to a production decision through a feasibility study. It is our belief that current market conditions favour projects that can supply high-grade process feed material, resulting in low unit costs, with modest up-front capital requirement. We believe that SMP presents such an opportunity.”

The purpose of the work reported here is to estimate new Mineral Resources at the Konokono and Gap deposits and update previous estimates for the Kenge, Mbenge, Porcupine and Snakebite deposits, where additional drilling and / or updated resource estimation methodologies have been applied.

Pit envelope constrained resources are reported at a 0.5 g/t Au cut-off within a pit shell using a $1,400/oz gold price. Underground potential was constrained within wireframes at a minimum mining width of 2.5 m and at a cut-off of 2.5 g/t Au.

The results are summarised in Table 1 below.

Classification  (g/t Au) (kt) (koz)
Indicated 2.4 7,539 590
Inferred 2.5 561 45

Resource Modelling

The new models are constrained by wireframes interpreted from geological evidence of mineralisation (shearing and alteration) and by using low grade (0.3 g/t Au) and high grade (2.5 g/t Au) cut-offs. For this estimate, Snowden created a single, domained model (using high-grade and low-grade kriging zones) for Kenge, Mbenge and Porcupine.

The drill hole database cut-off date for the resource estimate database was January 31, 2015. The drill hole database for the resource estimate contains a total of 375 diamond drill holes (DDH) for 68,592.45 m and 565 reverse circulation holes totalling 51,771.70 m.

The drill hole assay database consists of 64,677 samples, comprising 39,484 DDH samples and 25,193 RC samples.

Helio geologists logged the drill core and RC drill chips in detail on site, supervising sawing and bagging and sampling of half the core or RC chips from mineralized intervals. Remaining core is stored in a secured on-site location.

Continuous samples were taken from all RC drill holes. RC drilling conducted pre-2014 used 2m composite samples, whereas the 2014 onwards drilling uses individual 1m samples. For diamond drilling, pre-2010 sample lengths were determined by geology, but since then samples within the mineralised zones have been taken at a 1m length. Reference samples are retained on site. All samples were submitted to the laboratory with internal QA/QC checks including the use of blanks, standards and duplicates (at an average rate of 1 every 20 samples each.) Samples were assayed at the SGS Laboratory in Mwanza, Tanzania by 50g gold fire assay with an AA finish. As well as the Company’s internal QA/QC programme, SGS also applied their own internal QA/QC programme, consisting of insertion of standards and duplicates.

Block models were constructed in CAE DatamineTM software.

Snowden classified the Mineral Resource Estimate as Indicated or Inferred based on drill hole spacing, grade continuity, and reliability of data consistent with Canadian Institute of Mining (“CIM”) guidelines.

The accompanying NI 43-101 report will be made available on the Company’s website and under its profile at within 45 days of this news release.
