Emissions described in Scope 1 include use of light vehicles, drilling rigs, water pumps and heavy machinery by the Company and contractors. Decrease is observed in GHG emissions in comparisson to last year.
The percentage of its gross global Scope 1 GHG emissions that are covered under an emissions-limiting regulation or program that is intended to directly limit or reduce emissions, such as cap-and-trade schemes, carbon tax/fee systems, and other emissions control (e.g., command-and-control approach) and permit-based mechanisms 0.0000%
No regulation or program applies to the Company at this stage due to small volume of Scope 1 GHG emissions.
Discuss any change in its Scope 1 emissions from the previous reporting period, including whether the change was due to emissions reductions, divestment, acquisition, mergers, changes in output, and/or changes in calculation methodology (i.e. any changes the entity made to the measurement approach, inputs and assumptions during the reporting period and the reasons for those changes, if any) A small decrease is observed between past and current reporting year in emissions (gasoline, diesel, and LPG).
In the case that current reporting of GHG emissions to the CDP or other entity (e.g., a national regulatory disclosure program) differs in terms of the scope and consolidation approach used, describe the differences and provide those reported emissions. Not reporting at this stage due to small carbon footprint.
The entity may discuss the calculation methodology for its emissions disclosure, such as if data are from continuous emissions monitoring systems (CEMS), engineering calculations, or mass balance calculations Calculations are based on total annual fuel consumption.
Discuss short-term, medium-term and long-term  strategy or plan to manage its Scope 1 greenhouse gas (GHG) emissions Prime is an exploration company, as such, emissions are restricted to light vehicles and portable drill rigs. As a result, emissions are kept to a minimum and the Company's carbon footprint is small.

Prior to the transition to a development stage company, Prime will evaluate a long-term strategy to minimize or neutralize emissions when the Los Reyes Project enters development and is operational.
Please discuss reduction emissions target(s) (if any) for Scope 1 in your company, how they are set and analyse the performance against the target(s) Not applicable at this stage. The Company´s carbon footprint is quite small since operation only includes drilling rigs and light vehicles.

Targets will be defined when the Company reaches operational stage.

The Company’s relationships with the communities in which it operates, and other stakeholders are critical to ensuring the future success of the construction and development of its projects. In contrast to the many benefits that mining provides to communities including good paying long-term jobs, taxes paid to local and federal governments, infrastructure and other investments in local communities, improved roads, and access to remote areas, improved power and water access, and financial support of rural and low income communities nearby, there is an increasing level of public concern relating to the perceived effect of mining activities on the environment and on communities impacted by such activities. Publicity adverse to the Company, its operations, or extractive industries generally, could have an adverse effect on the Company and may impact relationships with the communities in which the Company operates and other stakeholders.

External opposition

Certain non-governmental organizations (“NGOs”), some of which oppose globalization and resource development, are often vocal critics of the mining industry and its practices. Adverse publicity generated by such NGOs could have an adverse effect on the Company’s reputation or financial condition and may impact its relationship with the communities in which it operates.
