About Antamina

The Mining Camp is located in YANACANCHA, in the Peruvian Andes, near the town of San Marcos at an altitude of between 4,200 and 4,500 meters above sea level.  In terms of climate, there are two clearly defined seasons; the dry season between April and September where it is primarily sunny and warm during the day but very cold at night; and the rainy season, between October and March.

The Port is located in Punta Lobitos, on the Pacific Coast, close to the city of HUARMEY. The climate is humid.  Similarly, there are two seasons; the summer season, between November and March, and the foggy season, between April and October.  The city of Lima has a similar climate.

Visitors must bring clothing that is suited to the weather conditions described above, including a rain coat, hat and gloves.  When the sun comes up, the intensity of sunrays is strong making the use of sunblock, sunglasses and lip gloss essential.  Steel toe boots are required when visiting both the Mine and the Port.

Because climate conditions can vary drastically from the Mine to the Port, if you intend to visit both locations, we recommend that you wear clothing that you can add on in layers or remove as needed.

About acute mountain sickness
The concentration of oxygen in the air is the same at any altitude. However, at higher altitudes, atmospheric pressure falls which leads to a lower pressure of oxygen entering the lungs and less oxygen passing into the bloodstream.   As a result, the activity of organs such as the heart, brain, lungs, digestive system and muscles become increased or diminished.  This is why pulse and breathing accelerate causing rapid heart rates or ‘agitation’ and digestion, muscular and mental activities become slower usually accompanied by symptoms of indigestion and headaches.   
Ascending to altitudes of over 2,500 meters above sea level (masl) can cause different clinical syndromes, including Acute Mountain Sickness (known as Soroche or Puna in Peru).

  • Head ache
  • Rapid heartbeat (palpitations)
  • Light or altered sleep pattern
  • Pale
  • Dizziness, nausea and/or vomiting
  • Shortness of breath

These symptoms can be alleviated with rest and analgesics such as aspirin and paracetamol (Panadol, Tylenol) or anti-inflammatory products like ibuprofen.

The administration of oxygen is prescribed when the first measures do not help.  In the majority of people these symptoms disappear after two days.  Everyone can be affected by these symptoms, even young and healthy people, regardless of age or physical condition.

About your health status

Compañía Minera ANTAMINA S.A. requires that all individuals who travel to the mine carry the Occupational Health Examination Report (Form 005) and/or the Medical Certificate for Altitude Ascent (Form 001A) as a medical requisite for your entry. The submission of one or both of these documents will depend on the nature of you visit to ANTAMINA’s facilities (workers or visitors). 

People who suffer from high blood pressure, chronic pulmonary, heart, neurological or metabolic disease must see their doctor and obtain written permission to travel. 

Classified as remote areas, our camps have well equipped medical facilities with doctors and emergency evacuation capability.  If you have scheduled a trip to our mine facilities and your clinical health status is unstable, you have a history of poor tolerance to high altitudes, fever or are suffering from some acute digestive or respiratory illness prior to the ascent, it is strongly advisable that you cancel your trip.

If you are taking any medication you must bring your written doctor’s prescription in the event it is requested upon entry.  Consult your doctor as to whether you need to make any adjustment to your dosage during the trip and bring a sufficient amount of medications with you in case you need to stay at the camp for more days than you had originally planned.  Also consult your doctor before you take any medication for altitude, such as Diamox (acetazolamide).

Please bear in mind that all of ANTAMINA’s facilities are considered alcohol and drug-free zones, where both the consumption and possession of these substances are prohibited.  Avoid consuming traditional coca tea or Trimate during the trip to the Mine since this may cause you to test positive in the drug tests which are taken at random in the Camp and are mandatory when so requested.  If you are a habitual consumer of coca tea, you must suspend your consumption one week before traveling to ANTAMINA.

About your trip
In the event that your trip to Peru is long, we advise that you stay in Lima for one day to recover.  If it is the first time you will be ascending to an altitude higher than 4,000 m.a.s.l., if you have had a bad experience with altitude or it has been a long time since your last experience at high altitudes, remain overnight at an intermediate altitude (e.g. Huaraz, a city situated at 3,100 m.a.s.l., 6 hours from Lima and 3 hours from the Mine by land) to become better adapted and where you may be examined by a doctor before traveling to the Mine.  

Eat lightly and sparingly. Avoid consumption of alcoholic beverages and coffee the night before and during the ascent.  Remember to abstain from drinking coca tea; you may drink other herbal teas (anise, lemongrass, and chamomile).

About your stay in the field

  • Eat lightly, reduce fat and avoid meals that produce gas.
  • Increase your intake of carbohydrates (rice, potato, pastas, bread), avoid excessive portions.
  • Avoid strenuous physical activity, smoking, sleeping pills and stimulants.
  • Increase intake of noncarbonated water.
  • Avoid sleeping with too much heat in the bedroom.

About the Tunan checkpoint

It’s located at Km. 12 of Route 14 PATIVILCA – CONOCOCHA, 100m before reaching the Tunan toll booth.  This post is the first checkpoint for those who are traveling from the Northern Pan American Highway toward ANTAMINA and where they will check the minimum safety equipment as required by standards:

  • Medical Forms: Form 005 (Occupational) and/or Form 001A (Ascent to Altitude)
  • First Aid Kit
  • Safety accessories, tire treads.
  • Internal cage (Pickup Trucks).
  • Means of communication with Antamina central communications center.
  • If your vehicle is going to enter the area of mining operations, you need a pole, a strobe light, a unit identification sign and a panic button.

When your vehicle passes the safety standards you will be given a certificate that you must show when passing through the Casablanca checkpoint and upon entering the Mine.  If you fail to meet the standards, you will have the chance to correct any substandard conditions in any nearby town.
IMPORTANT: It is mandatory to stop at checkpoints upon entering and leaving the area.

About the Casablanca checkpoint
Located at Km 9 along the Route Conococha-Mine. All vehicles heading to ANTAMINA are checked here. 

Those vehicles coming from a previous check in Tunán will be checked for administrative requirements prior to entry (Insurance, entry permits, etc.).

Those vehicles coming from Huaraz or other locations along that route will also be put through the same complete safety check as given at the Tunán Checkpoint.

IMPORTANT: It is mandatory for all to stop at checkpoints upon entering and leaving the area.
