Hummingbird’s exploration strategy aims to bring as much of the approximately 1.5Moz of Resources, not currently in Reserves, into the Life of Mine plan. The focus is on prioritising those areas that have the greatest impact to mine life, as well as discovering extensional resources within the licence area to ensure a healthy pipeline of ore Reserves.
Komana East Underground
An initial desktop study is being completed by external consultants DRA Global to target high-grades at depth beneath the current Komana East pitshell. The initial feedback of the study looks positive based on the current Indicated and Inferred Resources.
The 2018 exploration strategy will drill deep holes to target and convert currently Inferred Resources to Indicated category, adding mine life and improving the grade profile of operations towards the end of the current mine life.
Komana West has a 2.5+km strike length and is due to start being mined later this year. There is exploration potential to the North and South of the current pit design, with possible underground potential also.
Further work is to be carried out to quantify this upside in more detail.
Gonka is an exciting deposit on strike, 5km south of the Komana East pit, consisting of basalt and mafic dyke-hosted gold deposits with higher grades at depth. All resources for this deposit are Inferred and targeted to be converted into Measured and Indicated categories with the drilling planned for 2018.
This deposit has the potential to improve the operation’s production profile by improving the process plant feed grade in the middle years of the plant scheduled mine life.
Sanioumale East is a basalt and mafic dyke-hosted gold deposit similar to the Komana East and Gonka deposits. It has a 2.0km+ strike length and open mineralisation at depth, with only the weathered zone being historically drilled, leaving the fresh rock beneath open to drilling and additional Reserves.
More complex than Sanioumale East, Sanioumale west is a sediment hosted gold deposit with an ore body deometry favourable for good pit economics. Deposited similarly to Sanioumale East, the mineral resource is open at depth, as only the weathed zone was historically drilled, leaving the fresh rock open to drilling and additional reserves. A notable intersesection showing potential for underground development is 14m @ 4.21g/t from 138m depth.
Given its strategic location, 1.5km to the west of the Komana East open pit, the Life of Mine planning requirements may fast-track this deposit to top priority as a source of high-grade oxide material. Infill drilling is required to convert the current resource into Indicated and Measured reserves, which part of the 2018 exploration plan.
The Company aims to delineate an additional circa. 400kozs of Indicated and Inferred resources into Reserves, equivalent to a targeted circa. $22/reserve ounce.
|Gonka||385Koz @ 3.1g/t|
|Kabaya South||85Koz @ 1.3g/t|
|Malikila Permits (drill section)|
|25m @ 4.38g/t|
|5m @ 5.61g/t|
|8m @ 7.23g/t|
