Balmoral Releases Initial Resource Estimate for Martiniere Gold System, Detour Gold Trend Project, Quebec

 

 

 

 

 

Balmoral Resources Ltd. (TSX:BAR) (OTCQX:BALMF) today reported the initial resource estimate for the near surface portion of the Martiniere gold system on the Company’s wholly owned Martiniere Property in Quebec.  The initial resource estimate confirms the continuity of the gold mineralization within the Bug and Martiniere West Deposits and indicates potential for a significant portion of the currently outlined deposits (73%) to be extracted via open pit.

 

 

Over 93% of the estimated initial resource is contained within the upper 350 metres of the system. Expansion drilling below this level has begun and is currently anticipated to continue through the balance of 2018.  Balmoral’s drilling has confirmed that the Bug Gold Deposit continues to over 650 metres vertical depth, and is open below that, providing a clear path for near-term resource expansion. The present estimate does not include the recently discovered Bug NW Extension or several other promising recent gold discoveries on the property which all provide additional avenues for further expansion of one of the Abitibi’s newest gold systems.

 

 

INITIAL RESOURCE ESTIMATE

 

 

The initial resource estimate for the Martiniere Gold System has been prepared by Mr. Marc Jutras (P.Eng., M.A.Sc.) of Ginto Consulting Inc. and is summarized below. Mr. Jutras is an Independent Qualified Persons pursuant to NI 43-101.

 

  • At a 0.5 g/t cut-off grade the Martiniere Gold System is currently estimated to host an open pit-constrained Indicated gold resource of 431,000 ounces at an average grade of 2.0 g/t and an Inferred gold resource of 11,000 ounces at an average grade of 2.5 g/t
  • At a 2.5 g/t cut-off grade the System is currently estimated to host an additional underground Indicated resource of 159,000 ounces at an average gold grade of 4.5 g/t and an Inferred resource of 43,000 ounces at an average gold grade of 5.8 g/t 
  • 92% of the estimated resource is contained within Indicated Category

 

 

“The initial resource estimate for the Martiniere gold system, which outlines those resources occurring principally over the upper 350 vertical metres of the system, provides a strong base from which to continue to expand” said Darin Wagner, President and CEO of Balmoral. “The 2016 discovery of the Bug South deposit, and the multiple near surface discoveries since then, have provided the opportunity to outline a significant open pit resource at Martiniere, which could then potentially give way to underground development several years into any envisaged future operation. Our near-term focus at Martiniere will remain on the expansion of the gold system on multiple fronts.”

Resource Estimate Assumptions and Notes:

 

  1. The Independent and Qualified Person for the Mineral Resource Estimate, as defined by NI 43‑101, is Mr. Marc Jutras, P.Eng., M.A..Sc., Principal of Ginto Consulting Inc. The effective date of the Estimate is March 27, 2018
  2. These mineral resources are not mineral reserves as they do not have demonstrated economic viability.
  3. While the results are presented undiluted, the reported mineral resources are considered to have reasonable prospects for eventual economic extraction. The near surface mineral resource is constrained within an optimized open pit shell, while the below pit portion of the mineral resource is reported at an elevated gold grade cut-off
  4. The estimate includes several discrete zones/sub-zones of mineralization.
  5. Resources were compiled at gold cut-off grades of 0.5, 0.7 and 1.0 g/t gold for the evaluation of open pit estimates and at 2.0, 2.5 and 3.0 g/t gold for evaluation of underground estimates (see table below). The base case resource estimate is reported at a cut-off grade of 0.5g/t gold for resources constrained within the optimized pit shell and 2.5 g/t gold for resources outside the pit shell.
  6. Cut-off calculations for calculating the base case resource used: (all USD figures) $1.80/t for overburden removal, $2.00/t for open pit mining, $50.00/t for underground mining, $17.00/t for Processing (for both open pit and underground scenario’s), $2.50/t for G&A costs and mill recovery rates of 91%.
  7. Gold recovery rates of up to 91% have been achieved in limited testing for the Bug deposit. The Bug deposit comprises the majority of the estimated resource. Gold recoveries of.up to 97% to concentrate, and 72% overall, have been achieved in preliminary testing of the   Martiniere West Deposit.  
  8. For the open pit scenario pit slopes of 50 degrees were assumed in bedrock and 25 degrees in overburden.
  9. Calculations used a USD/CAD exchange rate of 1.22 and a gold price of US$1,300 in keeping with current long-term consensus estimates.
  10. Cut-off grade calculations would have to be re-evaluated in light of future prevailing market conditions (metal prices, exchange rate, and mining costs).
  11. Density values were estimated for all lithological units from measured samples. Density values for the mineralized zones were calculated from a measured density database.
  12. The resource was estimated using Vulcan software. The estimate is based on results from 490 diamond drill holes (91,988 m).The cut-off date for the drill hole database is January 30, 2018.
  13. High grade capping was done on composited assay data and established on a per zone basis.
  14. Compositing was done on drill hole intercepts falling within the mineralized zones (composite length of 1.0 m).
  15. Resources were evaluated from composited and capped drill hole assays using  3-pass ordinary kriging and inverse distance squared interpolation methods in a block model (block size = 2.5 x 2.5 x 2.5 m).
  16. The Mineral Resources presented herein are categorized as Indicated and Inferred based on drill spacing and geological and grade continuity. Based on the nature of the mineralization, a maximum average distance of composites of 40 m was used for Indicated resources in the Bug Deposit and 35 m in the Martiniere West Deposit. 
  17. Ounce (troy) = metric tonnes x grade / 31.10348. Calculations used metric units (metres, tonnes and g/t). Metal contents are presented in ounces.
  18. The number of metric tonnes and contained ounces were rounded to the nearest thousand. Any discrepancies in the totals are due to rounding effects
  19. The quantity and grade of reported Inferred resources in this Mineral Resource Estimate are uncertain in nature and there has been insufficient exploration to define these Inferred resources as Indicated or Measured, and it is uncertain if further exploration will result in upgrading them to these categories.
  20. CIM definitions and guidelines for mineral resources have been followed.
  21. The Qualified Persons are not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issue, that could materially affect the Mineral Resource Estimate.

 

 

The initial resource estimate for the Martiniere Gold System is based on results from 93,294 assays collected from 490 diamond drill holes representing in total 91,988 metres of drilling.

 

 

As indicated above, the base case initial resource includes both an open pit and an underground component reported at cut-off grades of 0.5 g/t and 2.5 g/t respectively after incorporation of estimates for operating costs based on those associated with mines currently operating in the local region, mill recoveries and overburden removal at an estimated long-term gold price of US$1,300. 

 

 

Figure 1 provides a plan view of the block models and optimized pit shells. Figure 2 and Figure 3 provide longitudinal sections through the block models for the Bug and Martiniere West gold deposits, both within the optimized pit shell and below. Both figures clearly demonstrate that the deposits are open for expansion down-plunge to depth. The majority of the initial indicated resource (76%) is contained within the Bug Gold Deposit.  Additional maps and sections are available at www.balmoralresources.com
