TORONTO, ON--(Marketwired - October 26, 2015) - Primero Mining Corp. ("Primero" or the "Company") (TSX:
P) (NYSE:
PPP)
today announces further extensions to the Deep Central Zone at the
Company's Black Fox mine, located near Timmins, Ontario, Canada. Primero
additionally reports the expansion of the Froome zone, located
approximately 1 kilometre west of the open-pit at its Black Fox Complex.
Highlights:
- Black Fox Continues to Grow at Depth: Wide intercepts demonstrate the continuation of high-grade mineralization at depth and include highlights of 16.0 grams per tonne ("g/t") gold over 11.9 metres (520-EX482-76) and 15.4 g/t gold over 10.9 metres (520-EX482-64) located over 800 metres below surface.
- Delineation Drilling Continues to Grow the High-Grade Deep Central Zone: Results from the Deep Central Zone including 10.9 g/t gold over 10.5 metres (580-F392-38A), 8.7 g/t gold over 9.1 metres (580-F392-37) and 9.2 g/t gold over 8.4 metres (580-F392-41) have given Primero increased confidence in the wide, high-grade mineralization characteristics of this zone.
- New Gold Zone Materializing at Black Fox:
Recent drilling from the Froome zone, located 1 kilometre west of the
Black Fox open-pit, include long mineralized intercepts of 5.1 g/t gold over 56.7 metres (15PR-G015),4.8 g/t gold over 52.4 metres (15PR-G007) and 5.1 g/t gold over30.9 metres (15PR-G013), demonstrating considerable continuity over long mineralized intervals.
- Gibson South Zone Shows Promise: Highlights include 5.2 g/t gold over 34.0 metres (GF15-1043), and 6.4 g/t gold over 7.0 metres (GF15-1045) at the Gibson South deposit, located 300 metres to the southwest of the Grey Fox Contact zone.
"Our
2015 exploration program at Black Fox continues to exceed expectations,
reaffirming our original investment thesis that the high-grade gold
mineralization is much more extensive than previously identified,"
commented Joseph F. Conway, Chief Executive Officer. "Exploration
drilling is already expected to have replaced our estimated full-year
underground production at Black Fox, encouraging us that with continued
success we'll be able to grow our resources beyond depletion this year.
The extension of the Froome zone into a wide, continuous mineralized
zone, located near the Black Fox mine confirms our belief that there
remains significant exploration upside outside of the identified
deposits at the Black Fox Complex."
Black Fox Continues to Grow at Depth
Today
Primero announces additional drilling from the Black Fox mine,
targeting the high-grade mineralization in the Deep Central Zone,
located between the mine's 600 metre level and the 820 metre level. Two
exploration holes have encountered the deeper extensions of this
mineralized zone, returning long intercepts including
16.0 grams per tonne ("g/t") gold over
11.9 metres (520-EX482-76) and
15.4 g/t goldover
10.9 metres (520-EX482-64). Both intersections are located over 800 metres below surface.
Delineation
drilling also targeting the Deep Central Zone continues to demonstrate
wide intervals of high-grade mineralization. Specific highlights include
10.9 g/t gold over
10.5 metres (580-F392-38A),
8.7 g/t gold over
9.1 metres (580-F392-37) and
9.2 g/t goldover
8.4 metres
(580-F392-41). The area remains open along strike and down dip and is
expected to continue to expand with the results of additional
exploration drilling.
Underground exploration drilling results are included in Table 1 with locations identified in Figure 1.

*All assays are capped at 30 g/t gold, average gold grades over core length widths.
Froome Zone Demonstrates Black Fox's Continued Prospectiveness
The
Company's surface drilling program at Black Fox has also been
successful in expanding the Froome zone discovery. The Froome zone,
located approximately 1 kilometre west of the Black Fox open-pit, was
initially encountered in late-2014 and intersected by the discovery hole
14BF-591 which targeted a strong Induced Polarization ("IP")
chargeability anomaly. Results from this initial hole were reported in
the Company's February 23, 2015 news release and highlighted a long
intercept of continuous mineralization grading
1.7 g/t gold over
66.0 metres. The Froome zone became a priority for 2015 surface exploration, and to-date 39 holes have targeted this new mineralized area.
Highlighted recent drill results from the Froome zone include
5.1 g/t gold over
56.7 metres (15PR-G015) and
4.8 g/t gold over
52.4 metres (15PR-G007)
both less than 200 metres below surface, and provide the Company with
confidence that this area could continue to expand. The Froome zone
continues to be a priority for surface exploration through the remainder
of 2015 and 2016.
The Froome zone demonstrates considerable
continuity of mineralization and extends laterally over 500 metres
dipping 70 to 75 degrees and is located along the highly prospective
Gibson-Kelore Fault Zone ("GKFZ"). The GKFZ has been interpreted to be a
southeast trending 2
nd order splay of the Destor Porcupine
Fault Zone ("DPFZ"), which is the major fault structure controlling much
of the gold mineralization in the Timmins Gold Camp. The GKFZ is
projected to originate from the DPFZ a few kilometres west-northwest of
the Black Fox deposit, trending southeast and gradually splitting near
the Grey Fox 147 zone at the south boundary of the Black Fox Complex
properties.
The GKFZ is an economically important regional
structure hosting a series of significant gold deposits including the
147, Contact, Gibson, and Gibson South zones at Grey Fox. It also hosts
the two Hislop open-pit deposits, and the Ross Gold Mine. These deposits
are all hosted along a 4 to 5 kilometre stretch of this fault.
Additional
drilling is still required to fully define the extension of the Froome
zone, which is open to the east, west, and at depth. The zone has been
traced to the bedrock surface, located 30 metres below the ground
surface level. Primero expects to complete approximately 9,000 metres
(30 holes) of additional drilling in 2015 at the Froome zone.
Highlighted
exploration drilling results from the Froome zone are included in Table
2 with locations identified in Figure 2. The true depth of the Froome
intercepts listed below is approximately 100 metres below surface.
Table 2: Froome Zone - Highlighted Surface Exploration Drilling Results
*All assays are capped at 100 g/t gold, average gold grades over core length widths.
**90 assay intervals (less than 1.0 metre each) are still pending for hole 15PR-G015.
Gibson South Zone Continues to Show Promise
Primero
also announces recent drilling results from its Grey Fox project,
located approximately 4 kilometres south-east of the Black Fox mine. The
Grey Fox project currently includes two potential open-pits at the
Contact and 147 zones, but the Grey Fox property also contains a number
of other mineralized zones (Grey Fox South, Whisky Jack, Gibson, and
Gibson South zones), all within close proximity to each other. These
zones also have the potential to become additional sources of ore as
part of the Black Fox Complex and are within trucking distance of the
Black Fox mill facility.
Similar to the Froome zone, as described
above, the Gibson South zone is also located along the GKFZ. The Gibson
South zone is located approximately 300 metres southwest of the Contact
Zone and south of the historic Gibson Decline, which was used in 1989 to
extract an 8,000 tonne bulk sample with an average grade of 27.4 g/t.
Recent drilling at the Gibson South zone has returned results including
5.2 g/t gold over
34.0 metres (GF15-1043).
Highlights of Gibson South zone exploration drill results are included in Table 3 with locations identified in Figure 3.
Table 3: Gibson South Zone - Highlighted Surface Exploration Drilling Results
*All assays are capped at 100 g/t gold, average gold grades over core length widths.
The
majority of 2015 drilling has been focused on infilling the Contact
zone. This drilling continues to confirm the continuity mineralization
within that zone. The two main Grey Fox area deposits, Contact zone and
147 zone have now been drilled off at 15 metre centres.
Highlights of Contact zone infill drill results are included in Table 4 with locations identified in Figure 3.
