Drilling Commences at Calibre
Antipa Minerals Ltd (“Antipa” or the “Company”) is pleased to announce
the commencement of the Calibre follow-up Phase 2 Reverse Circulation
(RC) drilling programme, being carried out as part of the initial $3 million
expenditure commitment under the Company’s recently announced Farmin
Agreement with Rio Tinto.
Anticipated Duration
The RC programme is estimated to take up to six weeks, dependent upon
a decision to proceed with the contingent Stage 3 portion of the
programme. Assay results are expected to follow completion of drilling.
Details of RC Programme
The RC programme will involve the completion of up to 30 RC drillholes
and up to 5,000m to be divided into three stages (refer to Figure 1)
extending up to 3.5km along strike from the northern most Calibre North
drilling as follows:
- Stage 1: East-west extensional RC drilling, approximately 1,000m,
across the 400m strike zone of broad high-grade gold-copper
mineralisation known as North Calibre defined by the 2015 Phase
1 RC programme (Figure 1);
- Stage 2: Extensional RC drilling, approximately 2,200m, of the high
priority magnetic target trend which extends for 1.2km to the north
of the Calibre North mineralisation (Figure 1); and
- Stage 3: Stage 3 reconnaissance RC drilling, up to 1,800m
contingent on the results from Stages 1 and 2, continuing north
along the same magnetic trend for up to a further 2.3km from the
high priority magnetic target being tested by the Stage 2 RC drilling
(Figure 1).
The main objectives of this three stage of RC drilling programme are to
extend the limits of the North Calibre high grade gold-copper
mineralisation to a total strike length of between 1.6 to 3.9km and
potentially identify regions of increased gold grade.
The Calibre high grade gold-copper mineralisation may extend over a total
strike length of up to 4.5km, including the Calibre South area and
depending on the success of the Phase 2 RC Calibre North programme,
with the mineralisation also remaining open to the south as supported by
the magnetic trends (refer to Figure 1).
