TORONTO and NEW YORK, May 28, 2019 /PRNewswire/ --
TSX and NASDAQ: MPVD
The updated Mineral Resource Estimate for the Faraday 2 kimberlite contains:
- 5.45 million carats of diamonds
- 2.07 million tonnes of kimberlite
- Average value of US$140 per carat
Mountain Province Diamonds Inc. ("Mountain Province", the "Company") (TSX and NASDAQ: MPVD) announces the filing on SEDAR of its National Instrument ("NI") 43-101 technical report titled "Project Exploration and Faraday Inferred Mineral Resource Estimate Update, Kennady North Project, Northwest Territories, Canada" dated effective April 24, 2019 (the "Technical Report"). The Technical Report describes the updated Inferred Mineral Resource of 5.45 million carats for the Faraday 2 kimberlite as previously announced on April 11, 2019. Also included is an update of exploration work conducted on the Kennady North Project to the end of 2018, and summaries for the Inferred Mineral resource of 1.90 million carats at the adjacent Faraday 1-3 kimberlite complex and the Indicated Mineral Resource of 13.62 million carats at the nearby Kelvin kimberlite.
The updated Inferred Mineral Resource for Faraday 2 includes 5.45 million carats of diamonds contained in 2.07 million tonnes of kimberlite, with an overall grade of 2.63 carats per tonne and an average value of US$140 per carat. This represents a 49% increase in total tonnes and a 74% increase in total carats for the Faraday 2 kimberlite. The Inferred Mineral Resource at Faraday 2 has been updated to include the northwest extension, which was discovered in 2017 and extended the kimberlite by 150 meters. The average value of US$140 per carat is a 25% increase from the 2017 average values of US$112 per carat, using a recoverable (+1 mm) diamond size frequency distribution for each geological domain.
The updated resource was determined by Aurora Geosciences Ltd. ('Aurora') and SRK Consulting Inc. ('SRK'), who were engaged by the Company to conduct the exercise.
President and CEO of Mountain Province Stuart Brown commented: "We are very pleased with the diligent efforts of our technical team in bringing to fruition the updated technical report for the Faraday 2 kimberlite. I thank the authors of the report, Mr. Gary Vivian of Aurora Geosciences, and Mr. Cliff Revering and Mr. Casey Hetman of SRK Consulting for delivering a professional product that enhances our value portfolio for the Kennady North Project."
Faraday 2 Updated Inferred Resource
The Faraday 2, Faraday 1-3, and Kelvin kimberlites are located approximately 10 kilometers northeast of the Gahcho Kué Mine. The Faraday 2 kimberlite is an irregularly shaped, inclined pipe-like body that has been drill delineated for over 600 meters and remains open to the northwest. The body varies in width between 30-50 meters and the vertical thickness ranges between 10-100 meters in subcrop at the southeast end beneath Faraday Lake, to about 50 meters thick at the furthest end of the northwest extension.
The full scope of the 2019 mineral resource update for Faraday 2 has incorporated the following components:
- An updated geology model that includes drill-delineation of the approximately 150-meter northwest extension;
- Additional microdiamond sampling of drill core and analysis of results from the northwest extension;
- Revision of the diamond size frequency distributions and revised estimates of average diamond grade for the four major kimberlite domains within Faraday 2, based either on commercial-sized (>1mm) diamonds recovered from large diameter drilling, or on grade projections derived from corresponding microdiamond data; and,
- Estimation of the average diamond value (US$ per carat) for each domain, based on the revised diamond size frequency distribution and a February 2019 re-pricing of the diamond parcels collected during 2016 and 2017 bulk sampling of Faraday 2 using large diameter reverse circulation drilling.
The geological model for Faraday 2 is based on drilling and bulk density data acquired to the end of 2018 that includes the northwest extension. The database is comprised of 22,183 meters of core drilling from 102 drill holes and 3,688 meters of large diameter drilling from 31 RC drill holes. A total of 811 bulk density measurements were derived from drill core within Faraday 2, of which 250 are located within northwest extension. A total of 6.42 tonnes of core was processed for microdiamonds, and 726.47 carats of +1 DTC sieve diamonds contained in 275.38 tonnes of kimberlite recovered by large diameter drilling were used for grade and value determinations. The 2017 valuation of the +1DTC diamonds was updated by WWW International according to their February 2019 price book. SRK then used the updated valuation to determine an adjusted value distribution model which was applied against the modeled size frequency distribution curves for each geological domain to derive a weighted average US$ per carat estimate for the Faraday 2 kimberlite. Due to the small quantity of carats available for grade and valuation estimates there is a high degree of uncertainty in these estimates; additional bulk sampling of Faraday 2 would increase the confidence in the diamond grade and value estimates.
SRK Consulting Inc. (Vancouver, B.C.) provided guidance on the evaluation program at Faraday 2 and recently completed a comprehensive review of geological, microdiamond, bulk sampling, and valuation results in order to estimate an Inferred Mineral Resource for the Faraday 2 kimberlite, as provided in the table below.
Inferred Mineral Resource Estimate for the Faraday 2 Kimberlite1 (effective date of February 28, 2019)
Kimberlite Tonnes Grade2 Carats Value (million tonnes) (carats per tonne) (million carats) (US$ per carat) Faraday 2 (2019) 2.071 2.63 5.45 $1403 1) The estimate includes the entire Faraday 2 kimberlite as defined by the current geological model, extending from the base of overburden (~390 masl) in the southeast to depths of approximately 160 masl 2) Grade is expressed as recoverable diamonds above 1 mm bottom cut-off 3) Average value is derived by applying a base case value distribution model to models of recoverable (+1 mm) diamond size frequency distribution for each geological domain. Some rounding error may occur in the values reported.
The NI 43-101 Standards and Canadian Institute of Mining and Metallurgy guidelines for Mineral Resources and Mineral Reserves stipulate that a Mineral Resource needs to have a "reasonable prospect of economic extraction of the specified ore". SRK concluded that the Faraday 2 kimberlite has reasonable prospects for eventual economic extraction. Inferred Mineral Resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
