Exploration expenditure guidance increased $10
million
Hecla Mining Company (NYSE:HL) today released its Q1 2021
exploration results.
Highlights
- Midas exploration at Green Racer Sinter intercepted high-grade
gold and silver mineralization over a 1,000-foot strike length and
a 1,250-foot dip extent in the Sinter Vein, as well as two new
mineralized footwall structures. Significant intercepts include
more than 5 oz/ton gold over 13 feet estimated true width (see
Table A for full results). All are open for expansion.
- Midas’ plan of operations amendment expands to allow greater
access to multiple targets on the Green Racer Sinter and East
Graben Corridor.
- San Sebastian exploration drilling on the El Bronco Vein
expanded mineralization over a strike length of 1,500 feet. While
at the El Tigre Vein, vein textures indicate drilling was high in
the epithermal system, warranting further deeper drilling.
“Our early exploration results, just two miles from the mine
portal, validates our thesis that despite its long high-grade
production history, there remains significant untouched potential
at Midas,” said Phillips S. Baker, Jr., President and CEO. “The
recent high-grade intercept grading 5.52 oz/ton gold and 8.9 oz/ton
silver over 20.3 feet drilled (13.1 feet estimated true width) is
one of the best exploration drillholes in North America in the past
year.”
Baker continued, “But maybe more important than the grade and
width of the discovery are the two additional mineralized
structures in the footwall of the main structure and that
significant mineralization continues over a strike of 1,000 feet
and a dip length of 1,250 feet. All structures are open along
strike and at depth.”
“At the end of April, we received the amended plan of operation
allowing further access to drill not only at this new high-grade
discovery but also to drill test targets on previously unpermitted
ground. While it is very early days in our exploration at Midas,
these successful results warrant expanding the number of drill rigs
from two to possibly four by the end of the year,” Baker
concluded.
Exploration expenditures were $6.0 million for the first
quarter, an increase of $3.4 million compared to the first quarter
of 2020 primarily due to increased activity and focus on the Green
Racer Sinter discovery at Midas and the El Bronco and El Tigre vein
discoveries at San Sebastian.
Exploration expenditures for 2021 are now expected to increase
$10 million to about $40 million to reflect the increased drilling
at Hecla’s properties.
Midas
At Midas, two core rigs focused on offsetting and expanding
high-grade mineralization along strike and up and down dip at the
Green Racer Sinter discovery made in the fourth Quarter of 2020. It
is anticipated that a third core rig will arrive at Midas in July,
and all three core rigs will focus on the Green Racer Sinter and
other East Graben Corridor targets. (Figure 1).
A detailed surface mapping program identified an outcrop of
spicular geyserite sinter, anomalous in gold, at the Green Racer
Sinter target, 2 miles east of the main Midas Mine. Previously
undrilled, Hecla’s drill program began in late 2020 and
successfully hit significant mineralization in multiple intercepts,
including 3.26 oz/ton over 3.9 feet estimated true thickness (see
release dated 2/18/21 and previous drill results included in Table
A below). The 2021 drill program is highlighted to date by 5.52
oz/ton gold and 8.9 oz/ton silver over 20.3 feet drilled (13.1 feet
estimated true width) including 8.89 oz/ton gold and 14.5 oz/ton
silver over 12.3 feet drilled (7.9 feet estimated true width)
(Figure 2). Mineralization is hosted in quartz and carbonate
veining within the Sinter structure which is locally fractured due
to post-mineral fault movement. Although early in the exploration
program, high-grade mineralization is defined over 1,000 feet of
strike length and 1,250 feet of dip extent and is open along strike
and down dip. Two additional mineralized structures (FW1 and FW2)
have also been intersected in the footwall of the Sinter structure
and both are open for expansion (Figure 2). Mineralization in these
footwall structures is like the Sinter structure with results that
include 0.71 oz/ton gold and 1.5 oz/ton silver over 2.0 feet
drilled (1.7 feet estimated true width) in the FW1 structure and
2.93 oz/ton gold and 1.6 oz/ton silver over 2.5 feet drilled (1.8
feet estimated true width) in the FW2 structure.
Also at Midas, the amended exploration plan of operations was
approved by the BLM in late April. This expanded exploration plan
of operations allows exploration of the strike extensions of the
Sinter and footwall structures as well as previously untested
targets (Figure 3).
More complete drill assay highlights from 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

San Sebastian
At San Sebastian, two core rigs focused on exploration drilling
in the El Bronco and El Tigre veins (Figure 4) that were discovered
in 2020 through our Short Vertical Reverse Circulation (SVRC)
drilling program. The 2021 SVRC drilling program was completed in
the first quarter within the Saladillo Valley using one reverse
circulation drill rig. Core drilling in the El Bronco vein defines
a wide zone of veining with 1,500 feet of strike length. Intercepts
during the quarter include 0.12 oz/ton gold and 16.2 oz/ton silver
over 28.7 feet true width and 0.10 oz/ton gold and 10.4 oz/ton
silver over 17.6 feet true width including 0.15 oz/ton gold and
15.5 oz/ton silver over 11.0 feet true width (Figure 5). The El
Bronco vein is a wide vein averaging 9.5 feet in true width with a
maximum width of up to 37.7 feet true width which occurs at depth
and to the west along strike. At the El Tigre vein, the most recent
offset drilling of the high-grade intercepts has been low grade
including 0.01 oz/ton gold and 2.0 oz/ton silver over 16.5 feet
true width, but the drilling appears to be high in the epithermal
system so deeper drilling is planned.
The San Sebastian SVRC drilling program over the last few years
has been instrumental in discovering mineralized veins under cover
of up to 60 feet of alluvial fill within the Saladillo Valley.
Numerous anomalies have been identified with SVRC drilling that are
untested with core drilling.
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
https://ir.hecla-mining.com/files/doc_presentations/2021/Hecla-Q12021-Exploration-Update.pdf.
Greens Creek
At Greens Creek, two underground core rigs focused on definition
drilling at the East Ore, Upper Plate, and 9A zones while
exploration drilling began testing the southern extensions to the
Gallagher Zone (Figure 6). Highlights from the East Ore Zone
drilling include intercepts containing 28.5 oz/ton silver, 0.33
oz/ton gold, 10.5% zinc and 3.7% lead over 19.9 feet and 8.9 oz/ton
silver, 0.18 oz/ton gold, 11.1% zinc and 2.9% lead over 34.5 feet,
both located at the hinge zone between the sub-vertical and
sub-horizontal portions of the East Zone. Highlights from the Upper
Plate Zone include intercepts containing 34.4 oz/ton silver, 0.12
oz/ton gold, 9.5 % zinc and 4.4% lead over 23.1 feet and 37.9
oz/ton silver, 0.13 oz/ton gold, 6.2 % zinc and 3.1% lead over 25.8
feet. Highlights from the 9A results include 24.50 oz/ton silver,
0.17 oz/ton gold, 14.34 % zinc and 9.32% lead over 21.0 feet and
30.37 oz/ton silver, 0.27 oz/ton gold, 8.22 % zinc and 4.01% lead
over 19.8 feet.

Casa Berardi
At Casa Berardi, five underground and two surface core rigs were
focused on definition drilling in the proposed WMCP and Principal
Pit areas as well as in the 118, 119, 123 zones and metallurgical
and in-stope drilling (Figure 7). Drilling in the WMCP Pit targeted
zones for metallurgical sampling and extensions above the current
resource to expand mineralization higher in elevation to the
bedrock-overburden contact. Highlights from this drilling include
0.03 oz/ton gold over 124.6 feet, 0.06 oz/ton gold over 92.2 feet
and 0.05 oz/ton gold over 78.1 feet. Assay results from drilling in
and near the 160 Pit from the 4th Quarter 2020 have been received
confirming continuity of mineralization within the 160 Pit.
Highlights from this drilling include 0.04 oz/ton gold over 38.7
feet, 0.08 oz/ton gold over 28.9 feet and 0.21 oz/ton gold over
16.1 feet including 0.90 oz/ton gold over 3.0 feet.
