CALIBRE, DISCOVERING THE POTENTIAL
We embrace change and innovation to help create an aligned team in order to outperform not only our peers but various financial products available in the marketplace today. We are fully invested and aligned with our shareholders – we have over $10 million invested in Calibre. Calibre Mining is a multi-asset gold producer focused on execution and building sustainable value for our shareholders, communities we operate in, and all stakeholders.
The Pavon property, located in central Nicaragua, is a low sulphidation system. Seventy one historical diamond drill holes totalling approximately 10,700 metres tested veins occurring over a strike length of six kilometres, with results that include 10.3 g/t gold over 16.8 metres in hole PADH-005B in the north zone and up to 6.7 g/t gold over 11 metres in hole PADH-01 in the south zone. During 2009 and 2010, we further explored the Pavon North and South Zones with 56 trenches totalling 1,608 metres. No exploration was carried out on the Pavon properties in 2012. Work was focussed on permitting for the drilling and small scale mining of Pavon.(1)
The Pavon property is located within the Natividad and Las Brisas exploration concessions totaling 31.5km2
After initial site visits and further review Calibre believes there is excellent potential to quickly advance the Pavon Gold Project. Pavon is located approximately 227 km from the El Limon Mine and 300 km from the La Libertad mine. B2Gold had historically and internally studied the potential to open pit mine at Pavon and truck the high-grade material to one of the processing facilities in country. Calibre is in the process of reviewing this potential opportunity and there are no certainties this can be done. Calibre is working on various permits to begin work again on the Pavon project and will be updating the market and progress and milestones are met. Calibre recently updated the NI 43-101 Resource Estimate at Pavon see details below.
July 28, 2020 Calibre Mining announced that the key environmental permit (Environmental Impact Assessment) had been approved for the development and production of Pavon Norte from the Ministry of the Environment and Natural Resources in Nicaragua
During the fourth quarter of 2019, Calibre initiated an Environmental Impact Assessment on the Pavon Gold Project. In addition, Calibre announced an updated resource estimate, which defined indicated resources totaling 1.39 million tonnes at 5.16 g/t Au containing 230,000 ounces of gold, and inferred resources totaling 0.57 million tonnes at 3.38 g/t Au containing 62,000 ounces of gold. The independent Technical Report on the Pavon Gold Project (written in accordance with National Instrument 43-101 standards), titled “Pavon Gold Project, Resource Estimation, Nicaragua” dated January 9, 2020 and effective November 12, 2019, prepared by WSP Canada Inc. is available at www.sedar.com under Calibre’s profile or on the Company’s website at www.calibremining.com.
Since the beginning of 2020, Calibre has continued to progress development at Pavon Norte, working closely with SLR Consulting (Canada) Ltd. (formerly Roscoe Postle Associates Inc.), WSP Canada Inc. and the Centre for an Understanding with Nature in Nicaragua, to ensure quality engineering designs with minimal impacts to the environment. Calibre has advanced engineering studies, mine plans, road construction designs, and socio-environmental initiatives focusing on water conservation and sustainable forestry and ranching. With road construction to the project currently underway, Calibre is well-positioned to commence open-pit ore production from Pavon Norte in the first quarter of 2021.
Calibre has also received the required permits to commence drilling on the Natividad mineral concession, the 1,300-hectare land parcel on which the Pavon Norte Gold Project is located. During the third quarter of 2020, a resource infill, geotechnical and waste dump condemnation drilling program will commence in support of the Pre-Feasibility Study, which is scheduled to be completed during the fourth quarter of 2020.
Calibre has identified the potential for resource expansion along strike and at depth and expects exploration drilling to commence during the fourth quarter of 2020.
(1) Mineral Resource estimates were compiled as of November 14, 2014.
(2) Mineral Resources are constrained within a pit shell and reported above a cut-off grade of 2.0 g/t gold, which was calculated using estimated project costs and a gold price of US$1,500 per ounce.
(3) Mineral Resources are constrained within a pit shell and reported above a cut-off grade of 1.15 g/t gold, which was calculated using estimated project costs and a gold price of US$1,400 per ounce.
El Limon Mine is located in northwestern Nicaragua, approximately 100 km northwest of the country’s capital, Managua. Click here for mine/project location map.
On October 15, 2019, Calibre completed the acquisition from B2Gold Corp. (“B2Gold”) of the producing El Limόn and La Libertad gold mines as well as the Pavon gold project and other mineral concessions in Nicaragua held by B2Gold for an aggregate consideration of $100 million, to be paid with a combination of cash, common shares and a convertible debenture. Following completion of the transaction, B2Gold will own an approximate 30% direct equity interest in Calibre. (Click here for the October 15, 2019 news release).
The El Limόn mining exploitation permit covers an area of 12,000 ha and was granted by Ministerial Decree for a 25-year term in 2002. The project also comprises the Bonete-Limόn, Guanacastal III, San Antonio, and Guanacastal II exploration permits, which are contiguous with the exploitation permit and cover a total area of 8,147 ha, and Villanueva 2 exploration permit, which is located 12 km north of the exploitation permit and covers an area of 1,200 ha.
Mining operations use conventional open pit mining methods at the Limón Central open pit and a combination of top-down and bottom-up sequenced longitudinal open stoping (LOS) at the Santa Pancha underground mines. The El Limón processing plant consists of agitated cyanide leaching and carbon adsorption, followed by carbon elution, electrowinning, and doré production. The annual throughput is approximately 500,000 tonnes per annum (tpa) and the historical recovery is 94% to 95%.
Calibre’s asset base includes multiple ore sources, 2.7 million tpa of installed mill capacity from two processing facilities (El Limon and La Libertad), reliable in-country infrastructure, and favourable transportation costs. The Company will continue to optimize its consolidated mine and process plans as the Company progresses our “hub-and-spoke” approach to maximizing value from our integrated asset base. This philosophy was demonstrated during Q1, 2020 at Libertad which delivered 21,449 ounces, despite the ongoing suspension at the Jabali underground mine, with approximately 20% of Libertad’s production sourced from Limon and Pavon.
