ESG — environmental, social, and governance performance — has moved from a reporting requirement to a core factor in how mining and exploration companies are evaluated by investors, regulators, and the communities they operate near. For an industry that inherently changes the landscape it works in, ESG criteria have become the framework for proving that growth and responsibility aren’t mutually exclusive.
Most conversations about ESG in mining focus on the biggest environmental line items: water use, tailings management, emissions, land rehabilitation. But sustainability performance is also built from smaller, more operational decisions — including something as ordinary as the material an exploration company chooses for its core trays.
Why ESG Has Become Central to Mineral Exploration
Mining and exploration activity has a direct and visible impact on ecosystems, air and water quality, biodiversity, and the communities located near operations — often in remote or economically vulnerable areas. That impact is exactly why ESG criteria carry so much weight in this sector specifically, more than in industries where the environmental footprint is less immediate.
For exploration companies, ESG performance breaks down into three practical questions:
- Environmental — How is the company managing its physical footprint, from waste and material use to water and energy consumption?
- Social — How does the company engage with the communities near its projects, and does it protect workers and local stakeholders?
- Governance — Is the company transparent about its practices, and accountable to the standards it claims to follow?
Many companies now use gap analysis to measure how their current practices compare to ESG benchmarks, identifying where operational choices — including procurement decisions — fall short of sustainability targets.
Why Investors and Communities Are Paying Attention
ESG is no longer a reputational nice-to-have. Investors and stakeholders increasingly use ESG performance to evaluate how a mining or exploration company manages its environmental impact, its social commitments, and its governance practices — and companies with weak ESG performance can face reduced access to capital as a direct result.
This shift has pushed sustainability considerations into parts of exploration operations that used to be treated as purely logistical. Material sourcing, waste generation, and supply chain choices are now part of the same conversation as tailings management and emissions reporting, because auditors and investors are increasingly looking at the full operational picture, not just headline environmental metrics.
Where Core Trays Fit Into the ESG Picture
Every exploration program generates a steady stream of consumable equipment needs, and core trays are one of the most consistent examples. Multiplied across hundreds of drill holes and years of programs, the material behind that equipment has a real cumulative environmental footprint — one that’s often overlooked next to bigger-ticket sustainability initiatives, but one that gap analysis frameworks are increasingly designed to catch.
Comparing the common tray materials through an ESG lens tells a fairly clear story:
| Material | ESG Performance |
| Wood | Consumes timber resources; typically discarded after a single field season due to rot and pest damage — generating recurring waste with no recovery value |
| Cardboard | Cheap but disposable by design; adds to landfill volume with each replacement cycle |
| Metal | Lasts longer structurally, but production carries a heavier environmental footprint; corrosion over time shortens usable life |
| Plastic | Long service life; no recurring waste stream from rot or rust; manufactured from recycled material and designed to be recyclable again — a genuinely circular footprint |
Coreplast’s Role in a Circular Approach to Core Storage
At Coreplast, we manufacture core trays to be part of that circular story on both ends: made from recycled plastic, and fully recyclable at the end of their working life. That combination directly addresses the environmental pillar of ESG in a way that’s measurable and easy for exploration companies to document in their own sustainability reporting.
How recycled plastic trays translate into ESG-relevant outcomes:
- Reduced waste generation — Trays that last through multiple drilling seasons instead of one reduce the volume of discarded equipment a project generates.
- Lower material footprint — Building trays from recycled plastic reduces dependence on virgin raw materials, including the wood sourcing that wood trays require.
- End-of-life recyclability — Trays that can be recycled again at the end of their service life close the loop instead of adding to landfill volume.
- Supply chain accountability — Choosing a supplier that can clearly document recycled content and end-of-life recyclability makes it easier for exploration companies to substantiate ESG claims in their own reporting, supporting the governance and transparency expectations investors are increasingly asking for.
None of this replaces the larger sustainability commitments a mining company has to make around tailings, water, or community relations. But ESG performance is cumulative, and equipment choices that seem minor — like the material behind a core tray — are part of the documented trail that increasingly matters to investors and regulators evaluating a company’s full environmental commitment.
The Bigger Picture: Small Decisions, Measurable Impact
The shift toward ESG-focused evaluation means that exploration companies can no longer afford to treat core trays as a purely logistical procurement item. Every material choice carries an environmental cost — and every choice to move toward recycled, durable, and circular alternatives contributes to a stronger ESG profile.
For companies looking to improve their sustainability performance, the path forward includes reviewing every consumable used in the field, from fuel and water to the trays that carry drill core from the rig to the warehouse. When that review identifies core trays as an area for improvement, recycled plastic trays offer a practical, measurable upgrade that aligns with environmental commitments without compromising performance.
At Coreplast, we design our products to support exploration teams in meeting both operational and sustainability goals. Our core trays are built to withstand the rigors of field work while reducing the environmental footprint of your program — from the material they’re made of to their end-of-life recyclability.

FAQs
How does ESG in mineral exploration relate to something as small as a core tray?
ESG performance is evaluated across a company’s full operational footprint, not just its largest environmental line items. Equipment choices made repeatedly across an exploration program — like the material used for core trays — contribute to the cumulative environmental impact that ESG frameworks and gap analyses are designed to measure.
Are recycled plastic core trays actually more sustainable than wood or metal alternatives?
Yes. Recycled plastic trays typically last longer than wood or cardboard, don’t generate the recurring waste associated with rot or pest damage, and can be recycled again at the end of their service life. That combination — recycled input, long service life, and end-of-life recyclability — gives them a more circular footprint than single-use or short-lifespan alternatives.
Why are investors increasingly interested in ESG performance in mineral exploration specifically?
Mining and exploration have a direct, visible impact on ecosystems and nearby communities, which makes ESG performance especially material to this sector. Investors use ESG criteria to evaluate environmental management, social responsibility, and governance transparency — and companies with weaker ESG performance can face reduced access to capital as a result.
What is gap analysis in the context of ESG?
Gap analysis is a tool companies use to measure how their current practices compare to ESG benchmarks or industry standards. It helps identify where operational choices — including procurement decisions like material selection for core trays — fall short of sustainability targets, and what changes are needed to close those gaps.
Can switching to recycled plastic core trays improve a company’s ESG rating?
Yes. While core trays alone won’t transform a company’s ESG rating, they contribute to the cumulative environmental performance that rating agencies and investors evaluate. Documenting the switch to recycled, durable, and recyclable trays provides verifiable evidence of improved procurement practices, which strengthens the environmental and governance pillars of ESG performance.
