K92 (TSXV – KNT) is pleased to announce the initial results from the ongoing grade control drilling programme at its high grade Kainantu Gold Mine, that is currently in the start-up phase. The results have significantly increased both the predicted grade and contained gold ounces in the first two planned production stopes.
- Grade increase from 5.82 gpt Au in original AMDAD Stope Model to 9.21 gpt Au
- Combined ounces in the two stope designs increase from 1,550 ozs Au to 2,390 oz Au
- Intercepts include 102 gpt Au over 1.1m and 9.21 gpt Au over 0.5m in GCDD 002 and 30.19 gpt Au over 2.5m in GCDD 001
In September 2016, K92 Mining Inc. (“K92”) commenced a campaign of close spaced underground diamond drilling as part of a comprehensive grade control strategy. This grade control drilling is designed to bring a significantly higher degree of confidence to the production planning and scheduling by drilling out all scheduled production areas underground ahead of actual development on a closed space pattern of approximately 15 metres by 15 metres. This compares with resource drilling which has been carried out of a 50 metre by 50 metre or greater pattern.
The initial grade control drilling intercepts included high grade gold intercepts including 102 grams per tonne gold (“gpt”) over 1.1 metres and 9.21 gpt gold over 0.5 metres in diamond drill hole GCDD 002 and 30.19 gpt gold over 2.5 meters in diamond drill hole GCDD001.
The results from this drilling are then used to finalize the various stope and ore development designs and provide updated information on projected production from the areas in terms of tonnage, grade and contained ozs. Table 1 below provides a comparison between the original AMDAD stope design and the new design based on grade control data, using both cut and uncut data. The stopes are situated at the lowest point in the underground which K92 have planned to mine and are also at the southern edge of the known resource that has only been drilled on a 100 metre by 100 metre pattern.
The updated stope designs based on the grade control drilling indicate the projected grade of the combined stopes has increased from 5.82 g/t Au in the original AMDAD stope model to 9.21 g/t (applying a top cut of 70 g/t Au) in the new stope model using the grade control results. The combined ozs in the two stopes has increased from 1,550 ozs Au to 2,390 ozs Au (applying the top cut of 70 g/t Au).

Table 2 and 3 below provides a summary of the results from the first six diamond grade control holes which have been drilled into the first two stope areas it is planned to be mined underground. Table 1 provides a summary of the significant intercepts from the holes, while Table 2 provides details of collar location and hole orientation.

Ian Stalker, K92 Chief Executive Officer and Director, states, “These results are very positive, as the stopes are located at the southern extremity of the resource where data is limited and significantly lower grades were expected. The results, combined with the results from the recently completed Preliminary Economic Assessment (“PEA”) on Kora reinforce our belief that this high grade gold system has significant expansion potential. The key focus of the technical team on site is the successful ramp up in our production from the Irumafimpa ore body and these first grade control results certainly indicate we are on track to achieve our targeted design production in the coming quarter.”
Recently, K92 Mining announced that initial gold production commenced at the Irumafimpa Gold Deposit and also announced results from a Preliminary Economic Assessment (“PEA”) completed at the Kora Gold Deposit, which the company is targeting to bring online in Q1 2018 (key results from the PEA include estimates of 108,000 AuEq ounces per annum of annual production at an all-in sustaining cost of $619/ozAuEq, cash flow of USD $558 million over a 9 year period, an NPV5 of USD $415 million and initial capital costs of USD $13.84 million. See K92 News Release dated October 13, 2016 for the full News Release). The ongoing drill program commenced concurrent with these achievements.
