International Graphite: Exploration drilling intersects additional new graphite mineralisation at the Springdale Graphite Project
HIGHLIGHTS
- Expanded exploration drilling program has commenced on the Springdale exploration and resource targets based on positive results to date
- Initial reverse circulation (RC) drilling of the previously undrilled target SDE_1 has intersected multiple new zones of graphite mineralisation
- Drilling remains shallow to approximately 100m
- The 39 hole RC program for ~3,160 metres, in progress at SDE_1, is approximately 2km east of the existing Springdale Mineral Resource
- SDE_1 was identified through airborne electromagnetic (AEM) survey data, again confirming the efficacy of AEM as an effective exploration tool
- Samples are being submitted for laboratory assaying as drilling progresses and are expected to be available within eight weeks
- At the completion of the SDE_1 program, rigs will be mobilised to the existing Springdale Mineral Resource and also the previously reported new discoveries at Springdale Far West and Springdale Central
Commenting on the progress of the expanded drilling program, International Graphite Limited (ASX: IG6) Executive Chairman Phil Hearse said, “Springdale has generated outstanding exploration results in 2022 and this expanded drilling campaign, based on the positive results to date, continues to highlight the prospectivity of our licenses.
“The latest visual intercepts from this campaign follow similar intercepts from our new discoveries at Far West and Central and indicate the significant upside to the existing Mineral Resource estimate at Springdale.”
Cautionary Statement: Any reference to visual estimates of graphite mineralisation in this report should not be considered a proxy or substitute for laboratory analysis for Total Graphitic Carbon (TGC), which are required to determine the widths and grade of the graphite mineralisation. Samples are being submitted for laboratory processing as drilling progresses and subject to laboratory performance are expected to be available within eight weeks.
Springdale Graphite Project Exploration Program
RC drilling has commenced at an exploration target known as SDE_1 which was identified by a prior AEM survey conducted over the Company’s exploration licenses at Springdale (see Figure 3).
The expanded drilling program consists of an additional 39 planned drill holes for approximately 3,160 metres. SDE_1 is located less than 2km from the existing Springdale Mineral Resource. It is one of seven high priority exploration targets identified by the AEM survey.
Drill collar data from drilling to date is shown below in Table 1 and visual graphite intercepts from drilling completed to date are shown in Table 2 and also Figure 2 for SGRC0088.
