Toronto, Ontario--(Newsfile Corp. - December 14, 2021) - Monarca Minerals, Inc. (TSXV: MMN) ("Monarca" or the "Company") is pleased to announce that it has received final assays for the last eight drill holes from its Phase 1 San Jose exploration drilling program. The assay results are summarized below in Table 1 and indicate significant Au, Ag, Cu, Pb, Zn and Mo mineralization. Significant Cu and Mo mineralization occurs in some drill holes, hosted in potassically and endoskarn altered intrusives.

Michael R. Smith, Monarca's Senior VP of Exploration commented, "We are pleased with the results of the Phase 1 drilling program at the San Jose project. The drilling indicates that the property has significant exploration potential, especially to the west of the areas drilled to date. The area to the west has mineralized intrusives at depth, which have long anomalous Au and Cu intercepts, overlain by strongly altered limestone, which has not yet been drilled from above. There is potential for skarn development at the un-drilled intrusive/limestone contact and Cu and Mo mineralization in altered intrusive rocks".

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 (Figure 1), is the site of the largest IP anomaly in the project area, which remains un-drilled from above where the dolomitized limestone outcrops (Figures 2 and 3). 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.

Quality Assurance and Quality Control Statement

Procedures have been implemented by Monarca to assure Quality Assurance Quality Control (QAQC) of all assaying that was done at an ISO Accredited laboratory. Drill hole samples are collected at the drill rig and are riffle or rotary split, disposing of 1/4 or 1/2 of the sample, resulting in the collection of two samples; one for the assay laboratory and one as a duplicate. The samples are then stored securely prior to shipment by the assay lab from site to the laboratory in Chihuahua city. A sterile blank sample (un-mineralized basalt) and a mineralized reference standard (used by Monarca since 2009) are alternately placed in the sample sequence every 20th sample. The assays received for the QAQC samples have been reviewed for acceptable values by Monarca's Qualified Person. Drillhole collar locations were measured with a Handheld GPS instrument, using the UTM DATUM WGS84 Coordinate System, which provides location within about 2m (Table 2: Drill Hole Collar Locations w/ Handheld GPS Instrument).
