RE:2019 Denver Gold Forum Presentationganndolp - Thank you for posting the Denver Gold Forum presentation.
I was wondering if you could publish some Bjorkdal 2020 Au production numbers using various underground grades of 1.5, 2.34, 3.37 and 4 g/t, and 0.7 g/t stockpile. Duffy indicated in the video that 2020 mill feeds would be 1M tonnes of underground ore and 300K low grade stockpile ore from above ground operations. I would use a spot price of $1500 USD per oz. I think the readers can extrapoliate revenue at higher Au prices.
I did a quick 2020 calculation using just 1M tons of underground ore at 4 g/t - I ignored the stockpile. The 2020 mill production would be 137,931 Au ozs or $206,896,551 USD. At 3 g/t, mill production would be 103,448 Au ozs or $155,172,413 USD.
What is the effect on the mining costs when more mill feed is coming from underground? Extra $25 USD/oz?
In the June investor forum video, Duffy mentioned concentrating on debt repayment is 2020. I remember calculating Gold Bond repayment to be approx. 419 Au oz /month over the remaining three years. Its about 5% of Bjorkdal annual production using 103,448 Au ozs/yr (estimate from above).
To conclude, Bjorkdal has an amazing story with a 10+ year LOM.
