Hecla Mining Company (NYSE:HL) today provided an update on its
exploration programs during the second quarter.
Exploration Highlights
- Casa Berardi:
- Drilling is expanding potential size of
the East Mine Crown Pillar (EMCP) pit and the proposed 160,
Principal and West Mine Crown Pillar (WMCP) open pits.
- Underground drilling of the 118 and 123
zones continues to discover high-grade mineralization along trends.
Surface drilling has defined high-grade extensions of the 124, 134
and south perimeter of the Principal Crown Pillar (123 Zone).
- At Lac Germain, 4.5 miles east of Casa
Berardi, drilling resulted in intersections of high-grade,
gold-bearing mineralized zones in at least five subparallel lenses.
Most of the gold-bearing lenses go to surface and the combination
of mineralized lenses extend approximately 2,200 feet along
strike and to a depth of 1,300 feet.
- San Sebastian: Continues to refine and
expand high-grade, polymetallic zones on the Middle and Francine
veins. Additional oxide mineralization being defined along the
Professor and East Francine veins.
- Greens Creek: Exploration drilling
continues to expand the Deep 200 South, Gallagher, East Ore, Upper
Plate and Southwest Bench zone mineralized trends.
- Nevada: Integration of the Klondex
exploration group is underway and drill programs are ramping
up.
“The exploration success we have seen across the portfolio in
recent quarters continues,” said Phillips S. Baker, Jr., President
and CEO. “The teams at Casa Berardi, Greens Creek and San Sebastian
are discovering high-grade material, both at surface and at depth.
A new focus is our 110-square-mile land package in Nevada where we
are integrating the existing exploration team and ramping-up
drilling.”
Casa Berardi – Quebec
During the second quarter, up to six underground drills were
used to refine stope designs, expand reserves and resources in the
118, 121, 123 and 124 zones and confirm further potential at depth
and to the east and west. Up to five drills on surface completed
infill and exploration drilling at the EMCP, WMCP, Principal, 134
and 160 zones. It is anticipated that once the resource is updated
and pit optimization studies are completed, these results will
extend the current EMCP pit to the west, potentially expand the
proposed Principal Pit, and provide the basis for a new pit design
of the WMCP. Deeper drilling has also identified high-grade zones
that extend from the proposed 134, 160 and Principal pits into the
underground where follow-up drilling has refined the geometry of
these higher-grade resources.
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 include
0.55 oz/ton gold over 3.3 feet and 1.49 oz/ton gold over 1.6
feet and drilling continues to expand this mineralized trend.
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. Near the top of the 123 Zone resource, step-out
drilling to the east has intersected 0.70 oz/ton gold over 15.3
feet and 0.50 oz/ton gold over 4.9 feet. Drilling from lower in the
mine has defined a new mineralized area north of the Casa Berardi
Fault. This new 125 Zone is a broad mineralized area that includes
higher-grade intervals such as 0.20 oz/ton gold over 9.8 feet.
Drilling below the current 123 Zone resource intersected 0.22
oz/ton gold over 21.2 feet and drilling further below the bottom of
the mine returned 0.45 oz/ton gold over 12.0 feet and 0.44
oz/ton gold over 9.1 feet suggesting these mineralized lenses
plunge west at depth and mineralization remains open. High in the
mine, drilling has targeted the east extension of the 124
Zone that is down-plunge of the Principal pit mineralization.
Exploration drilling is planned from underground to define this
trend.
Surface and shallow underground drilling have identified
extensions of potential pits that are being evaluated for
production. Drilling on the west extension of the current
EMCP Pit has returned 0.11 oz/ton gold over
40.3 feet, defining an extension of over 800 feet to the west
of the current pit outline. Shallow drilling is completed. Updated
block modeling and a final pit design shows the pit extending to
the west and slightly to the east. Surface exploration drilling
will follow up on the high-grade mineralization that was defined
along the 146 and 148 zones and will be evaluated for the
underground potential.
Surface drilling of the 134 and 160 zones below
the limits of the proposed pits intersected high-grade veins that
show continuity down-plunge to the east. Recent deeper drill
intersections of the 160 Zone include 0.16 oz/ton gold over 57.4
feet and 0.16 oz/ton gold over 41.7 feet and the high-grade shoots
within these intervals may have the potential for underground
mining. Significantly, the re-establishment of the underground
drill platforms in the East Mine below the 160 Zone could allow for
the evaluation of these high-grade shoots later this year and
possibly revive mining in this area.
Drilling of the WMCP to the west of the West Shaft
continues to intercept strong mineralized structures near surface
and shows the continuity of mineralization within 800 feet of
surface. This drilling is designed to evaluate the open pit
potential west of the West Shaft, and a significant number of
assays are pending. The WMCP resource modeling is in progress and
drilling results should be included in the end of year 2018
reserves. Drilling to the south of the proposed crown pillar in the
Principal Pit area confirmed continuity and includes
intersections of 0.04 oz/ton gold over 84.0 feet and 0.11 oz/ton
gold over 8.9 feet.
For the remainder of 2018, surface drilling programs are planned
at the 123-124 zones (Principal area), 146 Zone/EMCP, and WMCP
to define and expand these potential open pits along the Casa
Berardi Fault. Underground drilling is expected to continue to
expand and refine the 118 and 123 zones lower in the mine and the
123, 124, 134 and 160 zones closer to surface. Drilling of the 160
Zone from underground is planned to start in the third quarter with
the goal of increasing reserves and resources in the
newly-accessible East Mine.
Surface drilling at the Lac Germain prospect, 4.5 miles
to the northeast of the Casa Berardi mining lease and along a splay
of the Casa Berardi Deformation Zone, succeeded in defining five
gold-bearing mineralized lenses that extend approximately
2,200 feet along strike and to a depth of 1,300 feet from
surface. In the LG-1 lens, a drill hole returned 0.32 oz/ton
gold over 10.4 feet including 0.67 oz/ton gold over 3.5
feet. Along the LG-2 lens near-surface, drilling intersected an
exceptional value of 14.8 oz/ton gold over 1.7 feet
and a separate intersection of 0.20 oz/ton gold over
11.4 feet. At the LG-3 lens, drilling returned
0.18 oz/ton gold over 9.6 feet and
0.13 oz/ton gold over 7.5 feet. Finally, in Zone
LG-4, intersections of 0.17 oz/ton gold over
19.7 feet, 0.12 oz/ton gold over 24.7 feet and
0.19 oz/ton gold over 12.9 feet were reported.
In combination, the lenses are interpreted to form a 300-foot
wide structural and alteration corridor in a sequence of
sedimentary rocks including banded iron formation. Gold-bearing
mineralization is related to quartz and quartz-carbonate veins up
to 5 feet thick and is present close to surface and has
steep-to-sub-vertical plunges that are similar to the plunges of
gold mineralization at the Casa Berardi Mine. A number of these
lenses are open along strike and at depth and are expected to be
the focus of exploration in 2019. Surface drilling to the west of
the Casa Berardi Mining Lease has also extended mineralization
along the Casa Berardi Deformation Zone where one recently defined
lens has a similar style of mineralization to the 123 Zone at Casa
Berardi. The prospective Casa Berardi Deformation Zone and related
structural splays have a strike length of over 20 miles on the
property and should be the focus of exploration for many years.
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, four core drill rigs and one reverse
circulation (RC) drill operated, with two drills concentrated on
infill drilling of the polymetallic zone along the Francine
Vein. The other drills were active in exploration core
drilling which was directed toward the expansion of high-grade
polymetallic mineralization along the Middle Vein and shallower
exploration drilling of oxide mineralization along the Professor
and East Francine veins.
On the Francine Vein, infill holes within the
polymetallic zone intercepted intervals of semi-massive sulfide
that are generally consistent with the previous exploration
drilling results. Recent assays include 0.11 oz/ton gold, 13.2
oz/ton silver, 2.2% copper, 2.9% lead, and 4.6% zinc over 5.6
feet, and 0.01 g/ton gold, 10.2 oz/ton silver, 2.1% copper, 2.6%
lead, and 2.7% zinc over 10.0 feet. This drilling is
continuing to the east and at depth and is intended to refine the
resources prior to developing a mine plan. A bulk sample of the
polymetallic Francine Vein should occur in the fourth quarter and
provide material 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. Drilling continues to
intersect narrow, but high-grade mineralization including
intersections of 0.05 oz/ton gold and 18.8 oz/ton silver over 6.1
feet and 0.07 oz/ton gold and 21.2 oz/ton silver over 4.2
feet. The mineralized area is currently defined over 1,200 feet
along strike and 800 feet down-dip and drilling is now concentrated
on the 1,000 feet of open area located between these new intercepts
and the previously defined mineralization in the shallower portion
of the East Francine Vein resource area. 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.
Recent RC drilling intersected 0.02 oz/ton gold and 23.7 oz/ton
silver over 6.6 feet of oxidized quartz vein about 100 feet from
surface. This intercept is interpreted to be the projection of
West Francine Vein in an area located about 1,000 feet west
of any past drilling on the Francine Vein. Follow-up core drilling
of this target is planned in the third quarter. The Professor
Vein is located approximately 300 feet south of the Francine
Vein and some high-grade mineralization is located near a
programmed Francine Vein crosscut and could be accessed by
extending the current ramp from surface. Recent drilling of this
vein includes intersections of 1.03 oz/ton gold and 31.0 oz/ton
silver over 6.3 feet and 0.19 oz/ton gold and 47.6 oz/ton silver
over 4.9 feet. There appear to be three main pods of high-grade
mineralization along the Professor Vein; one that extends
vertically to surface and two pods that are located about 250 feet
from surface.
Exploration drilling of the West Middle Vein was
directed toward a new zone of high-grade mineralization with
similar mineral characteristics as the previously discovered
polymetallic mineralization on the Francine Vein. This zone extends
1,600 feet along strike and 1,400 feet down-dip and is open to the
east and at depth. The upper extent of this mineralization is
located about 100 to 300 feet below the new Middle Vein underground
mine ramp and work on a development drift has begun to facilitate
the collection of a bulk sample of the polymetallic mineralization
later this year. Recent intersections include 47.6 oz/ton silver,
0.19 oz/ton gold, 0.1% copper, 0.3% lead, and 0.5% zinc over 4.9
feet and 29.7 oz/ton silver, 0.07 oz/ton gold, 0.1% copper, 0.3%
lead, and 0.3% zinc over 2.3 feet. Drilling of this mineralization
along the Middle Vein is expected to continue to depth and to the
east.
Drilling continues to expand resources and evaluate polymetallic
targets along the Middle and Francine veins and will also evaluate
near-surface, oxide mineralization at the East and West Francine,
Professor and Esperanza veins.
More complete drill assay highlights from San Sebastian 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 second quarter and strong assay
results received from previous drilling in the first quarter have
upgraded and expanded the Deep 200 South, Gallagher, East Ore,
Upper Plate and Southwest Bench zone resources.
Drilling of the southern portion of the Deep 200 South
Zone, include intersections of 101.4 oz/ton silver, 0.09
oz/ton gold, 4.2% zinc and 2.1% lead over 8.0 feet. Confirmed bench
mineralization is present as two flat-lying, high-grade lenses and
upgraded it to an indicated resource. Exploration drilling south of
the current resource has extended 200 South Bench mineralization
another 250 feet with an intersection of 31.8 oz/ton silver,
0.01 oz/ton gold, 2.2% zinc and 1.0% lead over 23.6 feet. Deeper
drilling has defined a third, lower mineralized horizon along the
mine contact that has been folded to depth relative to the bench
mineralization. Recent exploration drilling to the south also
identified thin bench mineralization outside the modeled ore zone
to the west. Recent intersections in this area include 22.8 oz/ton
silver, 0.38 oz/ton gold, 2.7% zinc and 1.3% lead over 3.0 feet.
Shallow, east-dipping mineralization more than 250 feet west of the
modeled ore zone includes 39.9 oz/ton silver, 0.02 oz/ton gold,
1.3% zinc and 0.7% lead over 9.2 feet. Current exploration drilling
further south suggests the bench mineralization remains robust.
Drilling of the Gallagher Zone confirmed modeled
thicknesses and may have increased the resource and mineralization
further to the west. Intersections from this program include
10.6 oz/ton silver, 0.04 oz/ton gold, 2.0% zinc and 1.0% lead
over 23.9 feet. Exploration drilling also intersected ore
lithologies along and west of the Gallagher Fault. Future drilling
is planned to see if the current precious metal-rich mineralization
transitions into broader and higher-grade precious and base
metal-rich mineralization.
Drilling of the Upper Plate Zone suggests that there are
two, flat-lying ore zones near the mine portal elevation. Drill
results show the lower band of mineralization is similar in
thickness to the resource model, although it occurs beyond the
current wireframe to the west and south. South of the current lower
band, step-out drilling has intersected 42.9 oz/ton silver, 0.04
oz/ton gold, 3.1% zinc and 1.5% lead over 24.1 feet. The upper band
is thicker than the resource model, including 21.0 oz/ton silver,
0.02 oz/ton gold, 9.7% zinc and 5.8% lead over 20.8 feet, and
recent drilling has also extended this mineralization to the west
and south. Drilling from surface in the third quarter could expand
this resource further to the west and north.
Drilling of the Lower Southwest Zone indicates that the
newly-defined lower ore band extends farther to the north and
higher in elevation than modeled. Thick intercepts of white ores
and massive sulfide lithologies continue to be found beyond the
northern extent of the current resource. Recent drilling of the
upper remnant limb of the lower Southwest Zone shows the
mineralization in this section is much thicker than anticipated. In
the East Ore Zone intersections from definition drilling,
including 18.8 oz/ton silver, 0.24 oz/ton gold, 12.4% zinc and 4.7%
lead over 24.1 feet, confirm previously modeled resource estimates,
particularly at higher elevations. The focus of underground
drilling is planned to be on the Deep 200 South, Gallagher, East
Ore and Southwest Bench zones throughout 2018 with additional
drilling targeting the Northwest West and 9A zones.
Surface drilling commenced in June and the first three drill
holes have intersected broad zones of stockwork veining and 3 to
5-foot wide bands of semi-massive sulfide containing significant
sphalerite, galena and silver sulfosalts. This semi-massive sulfide
zone is about 800 feet west of the current 200 South Bench
resource and may represent part of a bench syncline that extends
appreciably along strike to the north and south.

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

Nevada
Fire Creek
Definition drilling at the Fire Creek Mine performed by Klondex
Mines was focused on upgrading and expanding resources in the
central Spiral 2 area and filling the gap to the Spiral
4 area in the southern part of the mine. Recent intersections
in Spiral 2 include 1.08 oz/ton gold over 4.1 feet and 0.65 oz/ton
gold over 3.0 feet and show the upside potential of resources in
close proximity to mine workings. Drilling has also extended Spiral
2 mineralization up-dip and to the north in the Joyce Splay with
intersections including 1.73 oz/ton gold over 1.8 feet.
Intersections including 0.46 oz/ton gold over 6.8 feet along the
Karen Vein indicate the structure continues south toward Spiral 4.
Additional drilling has in-filled and extended mineralization along
strike and up-dip in the Spiral 4 area. Underground development is
advancing on the Haulage 9 drift to provide an exploration drill
platform that is expected near year-end with the goal of extending
Spiral 9 veins to the south.
There are two surface exploration rigs operating at the Fire
Creek Mine to find extensions of current high-grade, gold-bearing
structures. Drilling at the Guard Shack, which is southeast
of the mine infrastructure, encountered structures with strong clay
alteration, which typically are gold-bearing, and suggest the
mineralization carries further south. Additional targets within the
Guard Shack area that will be evaluated with drilling include a
resistivity high to the west corresponding to a link structure
between Joyce and the Titan zones. Further south along known
structural corridors in the South Notice area, an Induced
Polarization (IP)/resistivity geophysical survey is in progress to
refine drilling targets for later in the year. The first surface
hole at the Zeus target, which is northwest of the mine
infrastructure, encountered a structure with strong alteration and
mineralization at the projected target depth. This is the first of
a projected eight holes that are designed to build upon strong
drill results from last year to the north and south along
strike.
Hollister
Two drill rigs concentrated on definition drilling in the
Central Hollister to refine resources next to and above the
mine infrastructure and evaluate the Gwenevere Vein and
Upper Gloria areas that are the eastern and western extents
of the mine, respectively. The Gwenevere program targeted
the 58, 59 and 60 veins and intersections include 1.58 oz/ton gold
and 13.5 oz/ton silver over 0.8 feet, 0.47 oz/ton gold and
0.60 oz/ton silver over 10.4 feet and 3.01 oz/ton gold and
13.6 oz/to silver over 0.4 feet and show the veins have good
continuity and remain open to the east. The Upper Gloria
intersections include 1.05 oz/ton gold and 67.2 oz/ton silver over
1.0 feet, 1.60 oz/ton gold and 11.2 oz/ton silver over 0.9 feet and
0.52 oz/ton gold and 10.8 oz/ton silver over 1.23 feet and
indicates these high-grade veins are open further to the west and
in the higher mining elevations. The Central Hollister
program was designed to follow up on historical reverse circulation
(RC) intercepts of the 213 Vein and to extend mineralization on the
151, 161 and 181 veins. Intersections include 1.65 oz/ton gold over
0.3 feet and 0.51 oz/ton gold over 2.2 feet and indicates
significant mineralization exists above the central mine area.
Surface drilling of the Rowena target is designed to
offset historic, high-grade intersections and extend the resource
east and west in the northern part of the mine. Two drills on the
Hatter Graben will start operating in August to test the
current Hatter resource east and west.
Midas
Exploration drilling is concentrated on the Trinity
target, which is a small, high-grade deposit south of the 3 Haulage
Extension at the south end of the Midas Mine. Although assays are
pending, surface drilling to the north and south suggests vein
mineralization may be strongest along the edges of the Trinity
Corridor and mafic dikes and appears to be open to both the south
and north.
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:

Other
Drilling in the quarter advanced the exploration of the Kinskuch
silver-base metals project in northern British Columbia, the Little
Baldy gold project in northern Idaho, and the Republic gold project
in Washington.
Updated Reserves and Resources (Incorporating Three Nevada
Mines)
A breakdown of the Company’s reserves and resources
incorporating the new reserves and resources from acquisition of
the Klondex Mines assets (Fire Creek, Hollister and Midas mines) is
set out in Tables B and C at the end of this news release. The new
table is a combination of Hecla Reserve and Resources (reported in
Hecla Mining Company press release February 7, 2018) and the
reserves and resources of the Fire Creek, Hollister and Midas
mines. The Fire Creek reserves and resources are those reported by
Klondex Mines on February 5, 2018 with mining depletion to April 1,
2018. Reserves and Resources for Hollister are those reported by
Klondex on July 13, 2017 with mining depletion to April 1, 2018.
The Midas Reserves and Resources have an effective date of June 30,
2017 and are also depleted to April 1, 2018.

Cautionary Statements to Investors on Reserves and
Resources
Reporting requirements in the United States for disclosure of
mineral properties are governed by the SEC and included in the
SEC's Securities Act Industry Guide 7, entitled “Description of
Property by Issuers Engaged or to be Engaged in Significant Mining
Operations” (Guide 7). However, the Company is also a “reporting
issuer” under Canadian securities laws, which require estimates of
mineral resources and reserves to be prepared in accordance with
Canadian National Instrument 43-101 (NI 43-101). NI 43-101 requires
all disclosure of estimates of potential mineral resources and
reserves to be disclosed in accordance with its requirements. Such
Canadian information is being included here to satisfy the
Company's “public disclosure” obligations under Regulation FD of
the SEC and to provide U.S. holders with ready access to
information publicly available in Canada.
Reporting requirements in the United States for disclosure of
mineral properties under Guide 7 and the requirements in Canada
under NI 43-101 standards are substantially different. This
document contains a summary of certain estimates of the Company,
not only of proven and probable reserves within the meaning of
Guide 7, but also of mineral resource and mineral reserve estimates
estimated in accordance with the definitional standards of the
Canadian Institute of Mining, Metallurgy and Petroleum referred to
in NI 43-101. Under Guide 7, the term “reserve” means that part of
a mineral deposit that can be economically and legally extracted or
produced at the time of the reserve determination. The term
“economically,” as used in the definition of reserve, means that
profitable extraction or production has been established or
analytically demonstrated to be viable and justifiable under
reasonable investment and market assumptions. The term “legally,”
as used in the definition of reserve, does not imply that all
permits needed for mining and processing have been obtained or that
other legal issues have been completely resolved. However, for a
reserve to exist, Hecla must have a justifiable expectation, based
on applicable laws and regulations, that issuance of permits or
resolution of legal issues necessary for mining and processing at a
particular deposit will be accomplished in the ordinary course and
in a timeframe consistent with Hecla’s current mine plans. The
terms “measured resources”, “indicated resources,” and “inferred
resources” are Canadian mining terms as defined in accordance with
NI 43-101. These terms are not defined under Guide 7 and are
not normally permitted to be used in reports and registration
statements filed with the SEC in the United States, except where
required to be disclosed by foreign law. The term “resource” does
not equate to the term “reserve”. Under Guide 7, the material
described herein as “indicated resources” and “measured resources”
would be characterized as “mineralized material” and is permitted
to be disclosed in tonnage and grade only, not ounces. The category
of “inferred resources” is not recognized by Guide 7. Investors are
cautioned not to assume that any part or all of the mineral
deposits in such categories will ever be converted into proven or
probable reserves. “Resources” have a great amount of uncertainty
as to their existence, and great uncertainty as to their economic
and legal feasibility. It cannot be assumed that all or any part of
such a “resource” will ever be upgraded to a higher category or
will ever be economically extracted. Investors are cautioned not to
assume that all or any part of a “resource” exists or is
economically or legally mineable. Investors are also especially
cautioned that the mere fact that such resources may be referred to

mineralization and grades of silver and/or gold estimated per ton,
is not an indication that such material will ever result in mined
ore which is processed into commercial silver or gold.

(a) Mineral reserves are based on $1200
gold, $14.50 silver, $0.90 lead, $1.05 zinc, unless otherwise
stated. (b) Mineral reserves are based on $1200 gold and $17.00
silver. (1) The term “reserve” means that part of a mineral deposit
that can be economically and legally extracted or produced at the
time of the reserve determination. The term “economically,” as used
in the definition of reserve, means that profitable extraction or
production has been established or analytically demonstrated to be
viable and justifiable under reasonable investment and market
assumptions. The term “legally,” as used in the definition of
reserve, does not imply that all permits needed for mining and
processing have been obtained or that other legal issues have been
completely resolved. However, for a reserve to exist, Hecla must
have a justifiable expectation, based on applicable laws and
regulations, that issuance of permits or resolution of legal issues
necessary for mining and processing at a particular deposit will be
accomplished in the ordinary course and in a timeframe consistent
with Hecla’s current mine plans. (2) Mineral reserves are based on
$1200 gold and a US$/CAN$ exchange rate of 1:1.4 Reserve diluted to
an average of 34.7% to minimum width of 9.8 feet (3 m). Open pit
mineral reserves of the Principal Mine were estimated in February
2011 by BBA Inc. based on $950 gold and a US$/CAN$ exchange rate of
1:1. Reserve diluted to 10% Technical Report on the Pre-Feasibility
