Monarca Minerals Inc. to announce that it has received final assays for the last eight drill holes from its Phase 1 San Jose exploration drilling program. All of the last eight drill holes were drilled at angles ranging from 45° to 60°, to cross contacts between
limestone and intrusives, where skarn mineralization occurs. Downhole surveys were completed for all of
the drill holes. The drill holes ranged from 152.4 m to 408.4 m of total depth.
Mineralization has been intersected in exoskarn and endoskarn and silicified intrusives, which are locally
potassically altered with shreddy biotite and potassium feldspar. The area to the west of the completed
drilling, where there is potential for skarn mineralization at the contact between mineralized intrusives
and overlying dolomitized limestone, is the site of the largest IP anomaly in the project area,
which remains un-drilled from above where the dolomitized limestone outcrops. The
mineralized intrusives have long intercepts of anomalous Au and Cu assays, indicating potential for
metalliferous skarn mineralization along the limestone/intrusive contact. Locally associated with Cu
mineralization are Mo grades up to 0.22% and 0.17%, as in drill holes SJ07 and SJ02, respectively. Drill Hole Summaries From Recent Assay Results: SJ02 - Drill hole SJ02 is located at the same location as SJ11 and was angled westerly. It intersected
1.5 m at 1.02 % Cu, with 0.20 grams/tonne (g/t) Au and 0.17 % Mo, hosted in potassically altered biotite
porphyry. The drill hole intersected long anomalous mineralized intervals in silicified biotite porphyry,
endoskarn and exoskarn, with 265.2 m at 0.02 g/t Au (at 0.005 g/t) and 50.3 m at 0.21 % Cu (at 0.1
%). Strongly dolomitized limestone outcrops above the intrusive, which provides potential for skarn
Mineralization; SJ04 - Drill hole SJ04 was drilled at the same location as drill hole SJ01, which as reported earlier had
an intercept of 3.0 m at 4.07 ppm Au, with 0.23 % Pb and 0.49 % Zn. Drill hole SJ04 was angled north-
easterly, to intersect the same mineralization, without success. SJ04 intersected 38.1 m of anomalous
Au mineralization, at 0.01 g/t. The current geological analysis underway will provide data to resolve the potential geometry of the mineralization discovered in SJ01; SJ05 - Drill hole SJ05 was angled north-westerly into the east side of a large IP anomaly, near the Buho
mine. It intersected 4.6 m at 0.94 % Cu with 0.3 g/t Au and 1.5 m at 0.42 g/t Au with 0.21% Cu. Long
intercepts of anomalous Au mineralization, 246.9 m at 0.05 g/t, were intersected, along with 68.6 m at
0.3 % Cu of anomalous Cu mineralization. Much of the anomalous mineralization is in intrusive rocks,
with silicification and endoskarn, which are overlain by strongly dolomitized limestone, providing a target
for skarn mineralization at the contact; SJ06 - Drill hole SJ06 was collared from the same location as SJ05, but angled westerly into a large IP
anomaly. It intersected 1.5 m at 0.94 % Cu and 0.30 g/t Au. It also intersected long intervals of
anomalous Au and Cu mineralization in exoskarn and altered intrusives, with 300.2 m at 0.03 g/t Au and
41.1 m at 0.16% Cu. The intrusive/limestone contact to the west and above the mineralized intrusive
provides a target for skarn mineralization; SJ07 - Drill hole SJ07 was angled westerly to target a mineralized shear zone and IP anomaly. It
intersected 1.5 m at 0.28 g/t Au. It also intersected 1.5 m at 0.22 % Mo, hosted in endoskarn with
potassic alteration in biotite porphyry, along with trace amounts of Cu and Au. It also intersected a long
interval of anomalous Au mineralization in altered intrusives, with 243.8 m at 0.02 g/t Au; SJ09 - Drill hole SJ09 was angled westerly to target an IP anomaly, in an area of altered intrusives and
limestone, with IP anomalies. It intersected 266.7 m at 0.01 g/t Au and 24.4 m at 0.20 % Zn. The
anomalous mineralization occurs in silicified intrusive rocks with localized endoskarn and exoskarn.
Dolomitized limestone outcrops to the west, in the area of a strong IP anomaly, which has not been
drilled from above, where skarn might occur at limestone/intrusive contacts; SJ13 - Drill hole SJ13 was drilled at the same location as drill hole SJ01, which as reported earlier had
an intercept of 3.0 m at 4.07 ppm Au, with 0.23 % Pb and 0.49 % Zn. Drill hole SJ013 was angled south-
easterly, to intersect the same mineralization at a higher elevation, without success. SJ13 intersected
106.7 m of anomalous Au mineralization, at 0.01 g/t. The current geological analysis underway will
provide data to resolve the potential geometry of the mineralization discovered in SJ01; SJ14 - Drill hole SJ14 was angled south-westerly to intersect a strong IP anomaly, at the contact
between altered intrusive rocks and limestone. It intersected intervals of anomalous Au mineralization,
with 56.4 m at 0.01 g/t. The mineralization is hosted in altered intrusives and limestone, with localized
skarn.
