Hecla Mining Company (NYSE:HL) today provided an update on its
exploration programs during the fourth quarter.
Exploration Highlights
- San Sebastian continues to expand
high-grade, polymetallic zones similar to the Hugh Zone on the
Middle and Francine veins.
- Casa Berardi has expanded and refined
resources that could increase the size of the proposed Principal
and current East Mine Crown Pillar (EMCP) open pits and discovered
mineralization that could lead to new pits in the west part of the
mine at the West Mine Pillar and NW-SW zones.
- Drilling of the 118 and 123 zones at
Casa Berardi has discovered high-grade mineralization at depth and
to the west.
- Greens Creek exploration continues to
expand the resource by drilling on known mineralized trends.
“Our strategy of investing in exploration continues to add
value, with considerable exploration success this year, including
the record silver, gold and lead reserves announced last week,”
said Phillips S. Baker, Jr., President and CEO. “This past quarter
was no different than the full year. We continue to expand the
polymetallic mineralization at San Sebastian, so much so that we
expect to take a bulk sample this year. At Casa Berardi, our
exploration continues to confirm the high expectations we had when
we acquired it, with expansions of planned pits and discovery of
new open pitable material as well as new high-grade lenses
underground. Finally, drilling at Greens Creek discovered
high-grade mineralization in the central part of the mine that
could enhance Greens Creek’s already exceptional mine economics and
mine life.”
San Sebastian - Mexico
During the quarter, exploration with three core drills that were
directed towards polymetallic mineralization successfully
discovered new high-grade zones along the Middle and
Francine veins.
Drilling of the 97 Zone along the West Middle Vein
was directed toward a new zone of high-grade, polymetallic
mineralization with similar mineral characteristics as the
previously discovered Hugh Zone on the Francine Vein. The 97 Zone
extends 1,000 feet along strike and 750 feet down-dip and is open
to the east and at depth. This mineralization is located about 100
to 300 feet below the new Middle Vein underground mine ramp and a
development drift has begun that will facilitate the collection of
a bulk sample of the polymetallic mineralization this year. Recent
assay results from step-out drilling include 10.2 oz/ton silver, 3%
copper, 10% lead, and 18% zinc over 4.4 feet and 12.0 oz/ton
silver, 4% copper, 6% lead, and 9% zinc over 5.4 feet. Drilling is
planned to the east and at 1,000 feet of depth to evaluate the
potential of polymetallic mineralization to extend below the 3,000
feet of strike length of the oxide reserves.
On the Francine Vein, drilling continues to intersect
high-grade, polymetallic mineralization extending 600 feet to the
west and 800 feet east of the current Hugh Zone resource for
a total of over 5,000 feet of strike length. Recent vein intercepts
suggest this polymetallic mineralization is closer to surface to
the west. Recent assay results from drilling on the Francine Vein
include 9.2 oz/ton silver, 2% copper, 5% lead, and 5% zinc
over 6.3 feet to the east and 12.8 oz/ton silver, 2% copper,
4% lead and 6% zinc over 3.6 feet to the west.
As noted in the last quarter, a drill hole located 2,500 feet to
the west of the Hugh Zone resource intersected a polymetallic vein
with over six feet of true thickness. Results of step-out drilling
in this area include 9.1 oz/ton silver, 3% copper, 3% lead,
and 4% zinc over 2.6 feet. The vein is one of the most western
intersections along the Francine Vein and is largely open between
the most recent drilling west of the Hugh Zone.
Drilling continues to expand resources and evaluate polymetallic
targets along the Middle and Francine veins and the plan is to also
evaluate near-surface, oxide mineralization at the Provessor, North
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:

Casa Berardi – Quebec
During the fourth quarter, six underground drills were used to
refine stope designs, expand reserves and resources in the 118,
123, and 124 zones and confirm further potential at depth, to the
west and in some cases to the east. Up to four drills on surface
completed in-fill and exploration drilling that could expand the
proposed Principal Pit and the current EMCP pit and discover new
mineralization that could lead to pits in the west part of the
mine.
At the Lower 118 Zone, drilling has confirmed the
continuity of multiple mineralized lenses that extend over 1,600
feet down-plunge and remain open to depth and to the east and west
of the current resources. Drilling near the bottom of the mine
returned 0.90 oz/ton gold over 21.9 feet and 0.38 oz/ton gold
over 37.8 feet and suggests there is good potential to extent
high-grade resources to the west and to depth near the Casa Berardi
Fault and below the current mine infrastructure.
Drilling of stacked, high-grade lenses of the 123 Zone is
defining the connection of multiple mineralized lenses for over
1,600 feet of strike length and over 3,000 feet down-dip below the
1010 level. Drilling on the western extreme of the lower 123 Zone
intersected 0.32 oz/ton gold over 37.1 feet, confirming the
continuation of multiple lenses. Also, to the east there was an
intersection grading 0.22 oz/ton gold over 24.0 feet. Drilling
below the mine infrastructure intersected 0.41 oz/ton gold over
10.7 feet and 0.35 oz/ton gold over 11.5 feet. Drilling of the
lower 123 Zone at the bottom of the mine confirmed vein continuity
and shows that it is open at depth and to the east and west of the
current resources.
Intersections from drilling on the upper part of the 124
Zone include 0.91 oz/ton gold over 4.6 feet and 0.42 oz/ton
gold over 17.7 feet, suggesting mineralization continues down from
surface and is open at depth and to the west. Drilling in this area
has also confirmed the high-grade nature of the crown pillar below
the proposed Principal Pit.
Surface and shallow underground drilling have identified
extensions of potential pits that are being evaluated for
production. Drilling along the northeast extension of the proposed
Principal Pit area confirmed 1,200 feet of continuity to the
northeast and includes an intersection of 0.11 oz/ton gold over 7.2
feet. Drilling targeting the shallow eastern extension of the 124
Zone intersected strong mineralization including 0.14 oz/ton gold
over 9.7 feet. Underground drilling of this target is planned to
evaluate deeper extensions of the high-grade shoots. Drilling on
the west extension of the current EMCP pit has returned 0.09
oz/ton gold over 27.8 feet and 0.07 oz/ton gold over 50.7 feet
to define an extension over 700 feet to the west of the current pit
outline.
Drilling of the West Mine Surface Pillar within 800 feet
of surface to the west of the west shaft intersected a broad
mineralized zone of 0.04 oz/ton gold over 78.7 feet that contains
an interval of 0.12 oz/ton gold over 13.8 feet. In-fill drilling in
2018 may convert a large portion of those resources to indicated
category with the eventual incorporation into the life of mine
plan.
Aggressive surface drilling programs are planned through 2018 at
the 124 Zone (Principal area), 146/EMCP, West Mine Surface
Pillar and South West zones to define a possible series of open
pits along the Casa Berardi Fault. Underground drilling is expected
to continue to expand and refine the lower 118, 121 and 123 zones
lower in the mine.
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:

Greens Creek – Alaska
At Greens Creek, drilling in the fourth quarter, targeting the
East Ore, Deep 200 South, Gallagher, Deep Southwest and West zones,
upgraded and expanded the known resources. Strong assay results
were also received from previous drilling on the East Ore,
Gallagher and Deep 200 South zones.
In the East Ore Zone intersections from definition
drilling, including 32.3 oz/ton silver, 0.18 oz/ton gold,
9.0% zinc and 4.8% lead over 19.8 feet, compare favorably to
previously modeled resource estimates, particularly at higher
elevations. Step-out drilling, including an intersection of 54.2
oz/ton silver, 0.43 oz/ton gold, 4.25% zinc and 1.34% lead over
19.0 feet, suggest strong mineralization continues beyond the
resource to the south and at depth. Aggressive drilling of the East
Ore Zone is planned to continue well into 2018 with the goal of
confirming reserves and expanding the known resource.
Definition drilling of the southern portion of the Deep 200
South Zone, including 40.1 oz/ton silver, 0.03 oz/ton
gold, 6.0% zinc and 4.2% lead over 18.9 feet, improved the
high-grades and upgraded it to indicated resource. Exploration
drilling south of the current resource has extended 200 South Bench
mineralization another 300 feet with an intersection of
23.6 oz/ton silver, 0.06 oz/ton gold, 2.5% zinc and 1.3% lead
over 19.5 feet. Recent exploration drilling further south suggests
the bench mineralization remains robust.
Drilling of the Gallagher Zone confirmed modeled
thicknesses and may have increased the resource by defining
mineralization further to the west and east beyond the current
resource. Intersections from this program include 25.3 oz/ton
silver, 0.01 oz/ton gold, 0.7% zinc and 0.3% lead over 9.4 feet and
8.4 oz/ton silver, 0.03 oz/ton gold, 11.8% zinc and 6.4% lead over
11.2 feet.
Underground drilling for the remainder of the year is planned to
focus on the East Ore, Upper Plate, Deep 200 South, and Gallagher
zones.

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
in ounces of silver and/or gold, rather than in tons of
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.
