Hecla Mining Company (NYSE:HL) today provided an update on its
exploration programs during the third quarter.
Highlights
- Largest quarterly exploration program
in company history
- There were up to 20 drills at 10
properties, 5 operating mines, all in North America
- Reserve price assumptions to determine
this year’s reserves are $14.50 silver, $1200 gold, $1.15 zinc and
$.90 lead, which are all at or below current spot prices and about
the same as last year. New reserves and resources will be provided
in first quarter of 2019
- Nevada:
- Underground drilling at Hollister is
identifying new mineralization in East Clementine and Gloria
areas.
- Surface drilling at Zeus (Fire Creek)
and Hatter Graben (Hollister) are expanding resources.
- Drilling and mine development programs
are revealing more potential than expected.
- Greens Creek:
- Underground drilling continues to
expand high-grade, near-surface resources at Upper Plate and East
Ore zones and add to mineralized trends along Deep 200 South,
Gallagher, and Deep Southwest zones.
- Surface drilling expands Upper Plate
resource and has identified bench mineralization 800 feet west of
200 South Bench resource.
- Casa Berardi:
- Surface drilling is expanding the
proposed Principal and West Mine Crown Pillar (WMCP) open pits and
defining high-grade shoots below and east of the Principal and East
Mine Crown Pillar (EMCP) pits.
- Underground drilling of the 118 and 123
zones continues to extend high-grade mineralization trends along
strike and at depth. Shallower drilling of the 123 and 124 zones
are extending high-grade shoots defined by previous surface
drilling.
- Drilling has begun at the East Mine to
define high-grade extensions of the 148 and 160 zones.
- San Sebastian:
- In-fill drilling has confirmed and
expanded the polymetallic resource on Francine Vein with bulk
sample planned later in the year; mine planning advancing for
2019.
- Additional oxide mineralization
discovered along the West Francine Vein and the newly-discovered
South Vein.
- The Esperanza, South and Andrea veins
define a continuous vein system that extends over 10 miles of
strike length with only limited exploration.
“With the addition of the Nevada assets, Hecla had the largest
quarterly exploration program in its history,” said Phillips S.
Baker, Jr., President and CEO. “While exploration expense will be
less in the fourth quarter, it is not for lack of good results. All
of Hecla’s programs this year had success that will justify
follow-up in the future. But our focus in the fourth quarter will
be at our Nevada operations and San Sebastian as we work towards
the sort of mine life that we have at Greens Creek and Casa
Berardi.”
Nevada
Fire Creek
There were two drill rigs operating underground at Fire Creek in
the third quarter. The first drill rig has recently started to
evaluate the upper portions of Spiral 3 along the Karen and Hui Wu
structures where a number of very high-grade headings suggest the
mineralization extends beyond the current resource (Figure 1). The
second drill rig has completed four of seven holes designed to test
the up-dip extent of Spiral 4 including the Joyce and 06 veins.
Additional definition drilling in the Spiral 2 and Spiral 4 areas
is expected to extend mine life by defining and upgrading new
resources. Other high-grade mineralized areas occur between Haulage
3 and Spiral 2 and will be the focus of future drilling.
Underground drift development is advancing Haulage 9 to provide an
exploration drill platform by early next year. This platform will
enable exploration drilling of the Spiral 9 veins with the goal of
expanding them to the north and south.
Three surface exploration rigs operated at the Fire Creek Mine
in the quarter with the goal of extending current high-grade,
gold-bearing structures. The drills are focused on two targets
including: 1) two drills at the Zeus target northwest of the mine
and 2) one drill at the Far View target southeast of the mine
(Figure 2). The first six surface holes drilled at the Zeus
target have intersected a continuous structure with strong argillic
alteration and mineralization typical of high-grade mineralization
in this area. Recent results, including intersections of 1.67
oz/ton gold over 1.2 feet and 0.46 oz/ton gold over 12.0 feet at
the margins of the basaltic dikes, confirm our positive opinion of
this target (Figure 3). Drilling continues to extend the resource
to the south and at depth. Drilling of the Guard Shack
southeast of the mine encountered structures with strong argillic
alteration typical of the gold-bearing structures in the area and
suggests the mineralization carries further to the south. West of
the Guard Shack target is a geophysical, resistivity-high target
that is believed to be a linking structure between the Joyce and
Titan zones and will be tested later this year.
An Induced Polarization (IP)/resistivity geophysical survey was
completed to the south along the known structural corridor, in the
South Notice area. The survey is designed to help refine
targets scheduled to be drilled later in the year and next year.
The survey identified a target which is interpreted to be either a
silica cap or sinter which is often associated with gold
mineralization. In addition, three north-south striking
chargeability highs were identified in the South Notice target
area. Anomalies like these could correspond to sulfide feeder
structures where gold mineralization may be found.
Hollister
Two rigs were active in the Central Hollister, East
Clementine and Gwenivere areas during the third quarter.
The Central Hollister programs targeted up-dip and lateral
extensions of the 141, 151, and 213 veins from 5190 level (Figure
4) and down-dip extension of the 182 vein from 5050 level. Drilling
intersected wide zones of mineralized breccia and narrower,
high-grade intersections included 1.0 oz/ton gold and 1.8 oz/ton
silver over 5.1 feet (141 Vein) and 1.06 oz/ton gold and 8.09
oz/ton silver over 3 .9 feet (151 Vein), and this mineralization
remains open up-dip. The drill program targeting the down-dip
extension of the 182 Vein included intervals of 4.0 oz/ton gold and
12.1 oz/ton silver over 3.1 feet (including 7.9 oz/ton gold and
23.2 oz/ton silver over 0.9 feet). These drill intercepts
strengthened the resource model in the area and confirm
mineralization is open at depth.
The East Clementine program targeted the 234, 243 and 253
veins at higher elevations near the unconformity where high-grade
concentrations of gold can occur. Multiple intervals of strongly
oxidized breccias and veinlets were intercepted including 0.60
oz/ton gold and 0.10 oz/ton silver over 3.0 feet (243 Vein)
(Figure 5). Additional drillholes are in progress to offset a
historical intercept of 1.78 oz/ton gold and 7.74 oz/ton silver
over 1.6 feet (233 Vein). Assays received from the first up-dip
hole of the three-hole drill program intersected 1.8 oz/ton gold
and 7.5 oz/ton silver over 1.6 feet which is about 90 feet from
current workings. Mineralization remains open along strike.
The Gwenivere program was designed to offset two
historical surface reverse circulation (RC) intercepts including
1.3 oz/ton gold and 0.05 oz/ton silver over 10.0 feet and 1.2
oz/ton gold and 0.13 oz/ton silver over 5.0 feet. Partial assays
from the first drillhole include 1.35 oz/ton gold and 0.29 oz/ton
silver over 3.0 feet. This new zone of mineralization is
approximately 1,500 feet from the portal and represents the
discovery of a new vein that is open in all directions. Initial
assays from recent underground drilling in the Gloria Vein,
at the west end of the mine, returned narrow assays of over an
ounce gold per ton including 1.10 oz/ton gold and 2.7 oz/ton silver
over 0.5 feet. Underground drifting is being extended to the west
to provide a drill platform for the western extension of this
high-grade mineralization. Additional definition drilling in the
Central Hollister, Gwenivere and West Gloria areas is being planned
for the fourth quarter.
Surface drilling of the Rowena Vein, at the south part of
the Hollister vein system (Figure 6), intersected strongly
brecciated and oxidized veining grading 0.19 oz/ton gold over 25.0
feet including 0.30 oz/ton gold over 5.1 feet. This style of gold
is more typical of the high-grade “blanket zone” which extends
along the unconformity upward into the base of the volcanic rocks.
Additional drilling could re-commence after all the assay results
are received. The first surface holes are in progress at Hatter
Graben with the intent to extend the current resource to the
east and west. Drill holes at 300-foot intervals have intersected
swarms with multiple veins and mineralized breccias at the
anticipated distance. Assays are pending.
Midas
Surface and underground exploration drilling on the
Trinity target, which is a small, high-grade deposit south
of the Midas Mine, was completed in August. Intersections including
0.47 oz/ton gold and 0.60 oz/ton silver over 4.5 feet and 0.51
oz/ton gold and 26.4 oz/ton silver over 2.5 feet, are associated
with silicification and banded quartz veins. This drilling suggests
vein mineralization may be strongest along the edges of the Trinity
Corridor and mafic dikes and appears to be open to both to the
south and north. The third quarter drilling extended the strike and
dip of several known high-grade ore shoots and filled in gaps of
the drill spacing, which should provide the confidence necessary
for an inferred resource category. The Trinity mineralization is
being remodeled in the fourth quarter in advance of a new resource
estimate by the end of the year.
More complete drill assay highlights from Nevada (Fire Creek,
Hollister and Midas) can be found in Table A at the end of this
release and a presentation showing drill intersection locations is
available at the following:

Greens Creek – Alaska
At Greens Creek, drilling in the third quarter and strong assay
results from drilling in the previous quarter have upgraded and
expanded the Deep 200 South, NWW, East Ore, Upper Plate and
Southwest Bench zone resources. Exploration drilling focused on the
Deep 200 South Zone, Gallagher Fault Block and Deep Southwest Zone
(Figure 7).
Definition drilling of the Deep 200 South Zone confirmed
three flat-lying, high-grade lenses that are folded to the west and
has enabled portions of bench mineralization to be upgraded to an
indicated resource category (Figure 8). Upper bench mineralization
is observed farther west and at a lower elevation than previously
modeled. Recent intersections include 41.3 oz/ton silver, 0.1
oz/ton gold, 3.2% zinc and 1.7% lead over 9.9 feet and 29.8 oz/ton
silver, 0.04 oz/ton gold, 15.5% zinc and 8.1 lead over 21.9 feet.
Definition drilling continued to target the southern portion of the
zone, and results include 63.0 oz/ton silver, 0.02 oz/ton gold,
4.7% zinc and 2.5% lead over 33.3 feet at the upper bench and 74.1
oz/ton silver, 0.13 oz/ton gold, 4.4% zinc and 2.1% lead over 23.0
feet at the lower bench.
Near the mine portal elevation, drilling of the Upper Plate
Zone suggests that there are two, flat-lying ore zones that are
folded to the west (Figure 9). The upper band of mineralization is
thicker than the resource model predicted, including 19.7 oz/ton
silver, 0.04 oz/ton gold, 6.1% zinc and 3.4% lead over 7.6 feet and
13.5 oz/ton silver, 0.02 oz/ton gold, 7.8% zinc and 3.4% lead over
20.2 feet. The lower band of mineralization occurs beyond the
current wireframe to the west and south and includes an
intersection of 41.1 oz/ton silver, 0.05 oz/ton gold, 1.9%
zinc and 1.0% lead over 3.5 feet.
The first surface drillholes southwest of the Upper Plate
Zone resource are also defining two mineralized limbs of a fold
that are present over 200 feet from the current resource and remain
open to the south, north, and west. Much of the mineralization is
proximal to the mine contact, but mineralized zones are also
present within the argillites. The mineralized zones vary from 4 to
11 feet in thickness and transition from white carbonate ore to
massive base metal ore and mineralized argillite. Assays for these
intervals include 6.7 oz/ton silver, 0.1 oz/ton gold,
7.6% zinc and 1.8% lead over 9.9 feet and higher-grade
intervals of 15.7 oz/ton silver, 0.2 oz/ton gold, 12.4% zinc and
3.9% lead over 7.6 feet and 8.4 oz/ton silver, 0.2 oz/ton gold,
13.4% zinc and 3.7% lead over 3.4 feet. The surface drill program
is complete for the year as final assay results should be received
in the next few weeks. Drilling from surface in the third quarter
could expand this resource further to the west and north creating a
substantial resource that may be in-fill drilled from underground
and incorporated into future Life of Mines (LOMs).
In the East Ore Zone intersections from drilling at the
north end, including 29.9 oz/ton silver, 0.28 oz/ton gold,
19.7% zinc and 10.3% lead over 3.5 feet and 39.7 oz/ton
silver, 0.39 oz/ton gold, 7.2% zinc and 3.0% lead over 5.0
feet, confirm previously modeled resource estimates, and are
particularly strong at lower and higher elevations. Drilling has
also expanded this northern portion of the zone at depth by over
100 feet. Drilling of targeted gaps between modeled ore zones
intersected mineralization that compares well in thickness and
location to existing trends. Assay results of the Southwest
Zone, including 29.1 oz/ton, 0.01 oz/ton gold, 9.0% zinc and
3.6% lead over 10.8 feet, confirmed and expanded the resource to
the west and north. Definition drilling of the NWW and
9A zones upgraded the resource model and extended
mineralization of the NWW further east to increase the resource.
Exploration drilling targeting the Deep Southwest
intersected mineralization 150 feet south of previous drill
intercepts including 34.9 oz/ton, 0.1 oz/ton gold, 8.0% zinc
and 3.7% lead over 13.9 feet.
The focus of the fourth quarter underground drilling is on the
Deep 200 South, East Ore and Upper Plate zones throughout 2018 with
additional drilling targeting the Northwest West and 9A zones.
Surface drilling has identified the western extension of the
200 South Bench mineralization from 700 to 900 feet west of
the current resource. Assays from the first five holes defined 3-
to 10-foot intervals of semi-massive sulfide that grade up to 12%
zinc and 3% lead with silver grades up to 1.5 ounces. This zone
includes intersections of 0.2 oz/ton silver, 12.1% zinc and 0.5%
lead over 3.2 feet and 0.4 oz/ton silver, 7.1% zinc and 1.0% lead
over 13.1 feet. This may represent part of a bench syncline
that is over 1,000 feet by 750 feet in area and could add
considerably to future resources.
Higher up in these surface holes, mineralization was intersected
at the mine contact and west of the Gallagher Fault. Drill
intersections of this mineralization include 1.1 oz/ton silver,
17.2% zinc and 3.5% lead over 3.4 feet. This is the first-time
mineralization has been intersected west of the Gallagher Fault
this far north (1,800 feet north of the Gallagher Zone
mineralization), potentially opening up a large area for
prospective exploration.

found in Table A at the end of this release and a presentation
showing drill intersection locations is available at the following:

Casa Berardi – Quebec
During the third quarter, up to six underground drills were used
to refine stope designs, expand reserves and resources in the 118,
121, 123, 124 and 125 zones, and confirm further potential at depth
and to the east and west (Figure 10). Up to four drills on surface
completed in-fill and exploration drilling at the West Mine Crown
Pillar (WMCP), Principal, 134 and 160 zones to potentially expand
the proposed Principal Pit, and provide the basis for an initial
pit design of the WMCP. Resource modeling and pit optimization
studies are completed and confirm the extension of the current East
Mine Crown Pillar (EMCP) pit to the west. Deeper drilling has also
identified high-grade zones that extend from the proposed 134, 160
and Principal pits into the underground.
At the Lower 118 Zone, drilling confirmed the continuity
of multiple mineralized lenses to the west and at depth outside the
current resource boundary. Recent intersections continue to expand
this resource, including 0.24 oz/ton gold over 25.8 feet and
0.20 oz/ton gold over 25.3 feet. An additional drill is
planned to move to the west end of the 990-drift to evaluate the
down-plunge to the west of the 118 Zone. Drilling of the Lower 118
Zone, at the bottom of the mine, has confirmed continuity of
resources and shown mineralization is open at depth.
Drilling of stacked, high-grade lenses of the 123 Zone is
defining the connection of multiple mineralized lenses for over
1,900 feet of strike length and over 3,600 feet down-dip below the
1070 level (Figure 11). Near the top of the 123 Zone, step-out
drilling to the east on the 430 level intersected 0.70 oz/ton gold
over 15.3 feet and 0.50 oz/ton gold over 4.9 feet and has shown
continuity with high-grade mineralization intersected with drilling
from surface. Drilling from the 970 level confirmed multiple lenses
that are expected to add to current mining reserves to the east.
Recent drill results from this area include 0.37 oz/ton gold over
11.0 feet and 0.30 oz/ton gold over 8.2 feet. Drilling below the
western extension of the current 123 Zone resource intersected in
this area include 0.40 oz/ton gold over 63.7 feet and 0.25 oz/ton
gold over 37.3 feet, and suggest these mineralized lenses plunge
west at depth and remain open for exploration.
High in the mine, drilling has targeted the east extension of
the 124 Zone that is down-plunge of the Principal pit
mineralization (Figure 12). Recent intersections just north of the
Casa Berardi Fault include 0.16 oz/ton gold over 41.6 feet and 0.22
oz/ton gold over 9.2 feet. Future drilling below the 290 level
should define this trend further to depth. The exploration of the
125 Zone from the 810 level focus drilling towards the north
and targeting splays of the Casa Berardi Fault to extend the 118
Zone to the east. Initial results are favorable, and recent
intersections include 0.34 oz/ton gold over 6.2 feet and 0.10
oz/ton gold over 10.5 feet, which confirm the model of
multi-stacked lenses along the Casa strike and open the exploration
east of the Principal Mine.
Definition drilling has commenced at the 300 level of the
East Mine to refine the depth extensions from surface of the
160 Zone. In the last quarter, a second drill is planned for the
485 level to define the high-grade plunge of the 148 Zone of the
East Mine.
During the third quarter exploration drilling on surface
targeted the west extension of the East Mine to investigate
the underground potential of the 146 and 148 lenses and East Mine
Crown Pillar (EMCP) open pit. Drills intersections in this area
including 0.16 oz/ton over 14.4 feet suggest that the 146 to 160
zone area is open over 1,600 feet west and 900 feet down dip of the
known resources. Drilling of the West Mine Crown Pillar
(WMCP) to evaluate open pit potential west of the West Shaft
continues to intercept strong mineralized structures near surface
(Figure 12). A recent intersection of 0.10 oz/ton gold over 90.0
feet includes an interval of 0.13 oz/ton gold over 34.4 feet. The
WMCP resource modeling is in progress and drilling results should
be included in the end of year 2018 reserves.
For the remainder of 2018, underground drilling is expected to
expand and refine the 118 and 123 zones lower in the mine and the
124-128 zones closer to surface. Drilling of the 160 Zone from
underground has begun with the goal of refining and expanding a
series of broad, high-grade veins in the newly-accessible East
Mine. Surface drilling programs are planned at the
128-129 zones (Principal area), to define and expand
underground mining potential east of the Principal area along the
Casa Berardi Fault.
More complete drill assay highlights from Casa Berardi can be
found in Table A at the end of the release and a presentation
showing drill intersection locations is available at the following:

San Sebastian - Mexico
During the quarter, three core drill rigs and one reverse
circulation (RC) drill operated at San Sebastian. Two drills
completed in-fill drilling in the central portion of the
polymetallic zone along the Francine Vein. Exploration core
drilling was directed toward shallower oxide mineralization along
the West and East Francine vein areas, the recently discovered
South Vein, and drilling re-started at the Esperanza Vein target
area (Figure 13).
At the Francine Vein, in-fill drilling within the
polymetallic zone intercepted intervals of semi-massive sulfide
with similar grade and width to the previous exploration drilling
results in this area (Figure 14). Strong drill results include 19.0
oz/ton silver, 4.8% copper, 16.0% lead, and 13.5% zinc over 4.5
feet and 7.3 oz/ton silver, 1.8% copper, 3.5% lead, and 5.7% zinc
over 7.4 feet. An updated Mineral Resource model has been completed
for the polymetallic zone of the Francine Vein and the in-fill
drilling program significantly increased the quantity of indicated
resource material. The model will be used to determine reserves,
mine design and scheduling. A ramp is now being driven toward this
area and a bulk sample is scheduled to be taken beginning in the
fourth quarter of 2018. The material from the bulk sample will be
used for metallurgical studies and a viability test of the nearby
Excellon Mill, where the processing of sulfide ores from San
Sebastian is planned.
Further to the east beyond the San Ricardo Fault, new zones of
vein-hosted, oxide mineralization have been defined by drilling
along the East Francine Vein (EFV) (Figure 14). Drilling
continues to intersect narrow, but high-grade mineralization
including intersections of 15.6 oz/ton silver and 0.01 oz/ton
gold over 4.8 feet and 9.6 oz/ton silver and 0.07 oz/ton gold
over 9.3 feet. Mineralization in this area is defined over 1,200
feet along strike and 800 feet down-dip and this new zone could
represent an important new source of oxide mineralization. When
incorporating the newly-defined mineralization in East Francine,
the total strike length of continuous mineralization along the
Francine Vein exceeds 8,000 feet and can be traced to a depth of
over 2,000 feet.
At the West Francine Vein, in an area located about 1,000
feet west of any past drilling on the Francine Vein, core drilling
followed up on a high-grade Reverse Circulation (RC) intersection
of 23.7 oz/ton silver and 0.02 oz/ton gold over 6.6 feet. The first
few drill core intercepts at the West Francine are narrow, but
high-grade including 57.6 oz/ton silver and 0.02 oz/ton gold
over 2.1 feet. Mineralization in this area is open laterally and at
depth. Follow-up, offset drilling is in progress.
Exploration drilling began at the Esperanza Vein area,
located approximately one and a half miles west of the mine area,
that is highly prospective but has not been core drilled since 2003
(Figure 16). The Esperanza Vein was cut two times in the third
quarter and both intercepts are wide (10.0 to 15.0 feet), contain
strong oxide material and appear to be moderately mineralized and
gold-dominant. Assays are pending for these intercepts and
additional drilling is currently in progress in this area.
Reconnaissance RC drilling recently discovered a new blind vein
under soil cover in the Saladillo Valley. This structure, referred
to as the South Vein is located approximately 1.2 miles southwest
of the San Sebastian mine area. The first three RC intercepts from
this vein returned 12.6 oz/ton silver and 0.08 oz/ton gold over 9.3
feet, 6.0 oz/ton silver and 0.03 oz/ton gold over 9.4 feet, and 5.6
oz/ton silver, 0.04 oz/ton gold over 9.4 feet. This vein is located
directly below a geochemical anomaly defined by Rotary Air Blast
(“RAB”) drilling. Other similar untested RAB anomalies occur in the
area.
The South Vein is located approximately halfway between the
Andrea Vein resource area to the southeast and the Esperanza Vein
to the northwest. Based on its location and orientation, this vein
may represent the link between these two known veins with a
prospective strike length of over four miles (Figure 15).
Mineralization in this area is open laterally and follow-up core
drilling program in this area is programmed for the fourth
quarter.
Drilling for the remainder of the year will continue to focus on
expanding resources and evaluate near-surface oxide mineralization
at the West Francine Vein, South Vein, and Esperanza Vein
areas.

Other
Drilling at Little Baldy in northern Idaho was completed
in August. The holes intersected narrow 0.5 to 3.0 feet wide, but
strongly mineralized veins with sulfides and trace visible gold.
Significant drill assays include 0.39 oz/ton gold over 0.8 feet,
0.21 oz/ton gold over 1.2 feet and 0.30 oz/ton gold over 1.1 feet.
At Republic, Washington the 4-hole Lone Pine/Blacktail
drilling program was completed and significant thicknesses of
low-grade, bulk-tonnage gold mineralization with several high-grade
intersections include 0.57 oz/ton gold over 6.1 feet,
0.21 oz/ton gold over 4.2 feet, and 2.1 oz/ton gold over 0.7
feet. Modeling is underway to assess whether the high-grade
intervals are extensions of veins mined historically or whether
they represent previously unidentified veins.

At the Kinskuch project in northern B.C. the drilling
program has just completed and defined silver-enriched, base metal
mineralization in the Illiance Valley for over a strike-length of
3.0 miles. High-grade zones appear to have continuity and may
represent two parallel mineralized structures or two limbs of a
folded body. The last of the assays are coming in and geologic
modeling in the Leapfrog program will feed into a preliminary
resource model.

Mineral Reserve Estimate for the Casa Berardi Mine, Northwestern
Quebec, Canada" effective date March 31, 2014 (the "Casa Berardi
Technical Report"), and for the San Sebastian Mine are contained in
a technical report prepared for Hecla titled "Technical Report for
the San Sebastian Ag-Au Property, Durango, Mexico" effective date
September 8, 2015. Also included in these four technical reports is
a description of the key assumptions, parameters and methods used
to estimate mineral reserves and resources and a general discussion
of the extent to which the estimates may be affected by any known
environmental, permitting, legal, title, taxation, socio-political,
marketing or other relevant factors. Information regarding data
verification, surveys and investigations, quality assurance program
and quality control measures and a summary of sample, analytical or
testing procedures for the Fire Creek Mine are contained in a
technical report prepared for Klondex Mines, dated November 30,
2017, amended March 2, 2018; the Hollister Mine dated May 31, 2017,
amended August 9, 2017; and the Midas Mine dated August 31, 2014,
amended April 2, 2015. Copies of these technical reports are
available under Hecla's and Klondex’s profiles on SEDAR at
www.sedar.com.
Dr. McDonald reviewed and verified information regarding drill
sampling, data verification of all digitally-collected data, drill
surveys and specific gravity determinations relating to the Casa
Berardi mine. The review encompassed quality assurance programs and
quality control measures including analytical or testing practice,
chain-of-custody procedures, sample storage procedures and included
independent sample collection and analysis. This review found the
information and procedures meet industry standards and are adequate
for Mineral Resource and Mineral Reserve estimation and mine
planning purposes.
