Alamos Gold Inc. (Alamos) has reported new results from surface and underground exploration drilling at the Island gold mine. Drilling throughout 2018, including new intercepts from the fourth quarter, continues to extend high-grade gold mineralisation across each of the Main, Western and Eastern Extensions. All reported drill widths are true width of the mineralised zones, unless otherwise stated.
“Island Gold has been a tremendous success story, both in terms of the growth of the operation and its mineral reserve and resource base. With excellent ongoing exploration success including several of the best surface directional holes ever coming in the latter part of 2018, we see strong potential for this growth to continue,” said John A. McCluskey, President and CEO.
2018 Drilling programme – Island gold mine
The focus of the 2018 exploration drilling programme was to expand the down-plunge and lateral extensions of the Island Gold deposit with the objective of adding new near mine Mineral Resources across the 2 km long Island Gold Main Zone.
Drilling completed in 2018 was successful in extending high grade gold mineralisation across all three areas of focus, including the Main, Western and Eastern Extensions. This has already translated into significant growth in both Mineral Reserves and Resources as detailed in the mid-year (30 June 2018) update (see press release dated 5 September 2018). Since the acquisition of Island Gold in November 2017.
Mineral Reserves have increased 28%, or 207 000 oz net of mining depletion, and Mineral Reserve grades have increased 17% to 10.69 g/t Au. Measured and Indicated Mineral Resources have also increased 142%, or 130 000 oz, and Inferred Mineral Resources have increased 18%, or 184 000 oz.
A total of 140 896 m of drilling in 719 holes was completed in 2018, including 75 441 m since the mid-year Mineral Reserve and Resource update. Drilling in 2018 included 48 942 m of surface directional exploration drilling, 8783 m of regional exploration drilling, 25 378 m of underground exploration drilling, 20,752 m of underground definition drilling and 37 041 m of underground delineation drilling.
A significant portion of the surface exploration drilling in the second half of 2018 focused on significant step-out holes and is too broadly spaced to define Inferred Mineral Resources. These areas will be infilled during 2019.
